Early contributions to biology were made by Catholic scientists such as Jean-Baptiste Lamarck and the Augustinian friar Gregor Mendel. Since the publication of Charles Darwin's On the Origin of Species in 1859, the attitude of the Catholic Church on the theory of evolution has slowly been refined. For nearly a century, the papacy offered no authoritative pronouncement on Darwin's theories. In the 1950 encyclical Humani generis, Pope Pius XII confirmed that there is no intrinsic conflict between Christianity and the theory of evolution, provided that Christians believe that God created all things and that the individual soul is a direct creation by God and not the product of purely material forces. Today, the Church supports theistic evolution(ism), also known as evolutionary creation, although Catholics are free not to believe in any part of evolutionary theory.
The Catholic Church holds no official position on the theory of creation or evolution, leaving the specifics of either theistic evolution or literal creationism to the individual within certain parameters established by the Church. According to the Catechism of the Catholic Church, any believer may accept either literal or special creation within the period of an actual six-day, twenty-four-hour period, or they may accept the belief that the earth evolved over time under the guidance of God. Catholicism holds that God initiated and continued the process of his evolutionary creation and that all humans, whether specially created or evolved, have and have always had specially created souls for each individual.
Catholic schools in the United States and other countries teach evolution as part of their science curriculum. They teach the fact that evolution occurs and the modern evolutionary synthesis, which is the scientific theory that explains how evolution proceeds.
Catholics' contributions to the development of evolutionary theory included those of the Jesuit-educated French scientist Jean-Baptiste Lamarck (1744-1829) and of the Augustinian monk Gregor Mendel (1822-1884). Lamarck developed Lamarckism, the first coherent theory of evolution, proposing in Philosophie Zoologique (1809) and other works his theory of the transmutation of species. He constructed a genealogical tree to show the genetic connection of organisms.
Mendel entered the Brno Augustinian monastery in 1843, but also trained as a scientist at the Olmutz Philosophical Institute and at the University of Vienna. The Brno monastery was a centre of scholarship, with an extensive library and tradition of scientific research. At the monastery, Mendel discovered the basis of genetics following long study of the inherited characteristics of pea plants, although his paper Experiments on Plant Hybridization, published in 1866, remained largely overlooked until the start of the next century. He developed mathematical formulae to explain the occurrence, and confirmed the results in other plants. Where Darwin's theories suggested a mechanism for improvement of species over generations, Mendel's observations provided explanation for how a new species itself could emerge. Though Darwin and Mendel never collaborated, they were aware of each other's work (Darwin read a paper by Wilhelm Olbers Focke which extensively referenced Mendel). Bill Bryson writes that "without realizing it, Darwin and Mendel laid the groundwork for all of life sciences in the twentieth century. Darwin saw that all living things are connected, that ultimately they trace their ancestry to a single, common source; Mendel's work provided the mechanism to explain how that could happen". Biologist J. B. S. Haldane and others brought together the principles of Mendelian inheritance with Darwinian principles of evolution to form the field of genetics known as the modern evolutionary synthesis.
Changing awareness of the age of the Earth and fossil records helped in the development of evolutionary theory. The work of the Danish scientist Nicolas Steno (1638-1686), who converted to Catholicism and became a bishop, helped establish the science of geology, leading to modern scientific measurements of the age of the earth.
Catholic concern about evolution has always been very largely concerned with the implications of evolutionary theory for the origin of the human species; even by 1859, a literal reading of the Book of Genesis had long been undermined by developments in geology and other fields. No high-level Church pronouncement has ever attacked head-on the theory of evolution as applied to non-human species.
Even before the development of modern scientific method, Catholic theology had allowed for biblical text to be read as allegorical, rather than literal, where it appeared to contradict that which could be established by science or reason. Thus Catholicism has been able to refine its understanding of scripture in light of scientific discovery. Among the early Church Fathers there was debate over whether God created the world in six days, as Clement of Alexandria taught, or in a single moment as held by Augustine, and a literal interpretation of Genesis was normally taken for granted in the Middle Ages and later, until it was rejected in favour of uniformitarianism (entailing far greater timeframes) by a majority of geologists in the 19th century. However, modern literal creationism has had little support among the higher levels of the Church.
The Catholic Church delayed official pronouncements on Darwin's Origin of Species for many decades. While many hostile comments were made by local clergy, Origin of Species was never placed on the Index Librorum Prohibitorum; in contrast, Henri Bergson's non-Darwinian Creative Evolution (1907) was on the Index from 1948 until the Index was abolished in 1966. However, a number of Catholic writers who published works specifying how evolutionary theory and Catholic theology might be reconciled ran into trouble of some sort with the Vatican authorities. According to the historian of science and theologian Barry Brundell: "Theologians and historians of science have always been struck by the seemingly enigmatic response of Rome when it did come; the authorities were obviously unhappy with the propagation of 'Christianized evolution', but it seems they were not willing or able to say so straight out and in public". H.L. Mencken observed that:
[The advantage of Catholics] lies in the simple fact that they do not have to decide either for Evolution or against it. Authority has not spoken on the subject; hence it puts no burden upon conscience, and may be discussed realistically and without prejudice. A certain wariness, of course, is necessary. I say that authority has not spoken; it may, however, speak tomorrow, and so the prudent man remembers his step. But in the meanwhile there is nothing to prevent him examining all available facts, and even offering arguments in support of them or against them—so long as those arguments are not presented as dogma.
The first notable statement after Darwin published his theory in 1859 appeared in 1860 from a council of the German bishops, who pronounced:
Our first parents were formed immediately by God. Therefore we declare that the opinion of those who do not fear to assert that this human being, man as regards his body, emerged finally from the spontaneous continuous change of imperfect nature to the more perfect, is clearly opposed to Sacred Scripture and to the Faith.
The concentration of concern on the implications of evolutionary theory for the human species was to remain typical of Catholic reactions. No Vatican response was made to this, which some have taken to imply agreement. No mention of evolution was made in the pronouncements of the First Vatican Council in 1868. In the following decades, a consistently and aggressively anti-evolution position was taken by the influential Jesuit periodical La Civiltà Cattolica, which, though unofficial, was generally believed to have accurate information about the views and actions of the Vatican authorities. The opening in 1998 of the Archive of the Congregation for the Doctrine of the Faith (in the 19th century called the Holy Office and the Congregation of the Index) has revealed that on many crucial points this belief was mistaken, and the periodical's accounts of specific cases, often the only ones made public, were not accurate. The original documents show the Vatican's attitude was much less fixed than appeared to be the case at the time.
As to the Divine Design, is it not an instance of incomprehensibly and infinitely marvellous Wisdom and Design to have given certain laws to matter millions of ages ago, which have surely and precisely worked out, in the long course of those ages, those effects which He from the first proposed. Mr. Darwin's theory need not then to be atheistical, be it true or not; it may simply be suggesting a larger idea of Divine Prescience and Skill. Perhaps your friend has got a surer clue to guide him than I have, who have never studied the question, and I do not [see] that 'the accidental evolution of organic beings' is inconsistent with divine design—It is accidental to us, not to God.
In 1894 a letter was received by the Holy Office, asking for confirmation of the Church's position on a theological book of generally Darwinist cast by a French Dominican theologian, L'évolution restreinte aux espèces organiques, par le père Léroy dominicain. The records of the Holy Office reveal lengthy debates, with a number of experts consulted, whose views varied considerably. In 1895 the Congregation decided against the book, and Fr. Léroy was summoned to Rome, where it was explained that his views were unacceptable, and he agreed to withdraw the book. No decree was issued against Léroy's book, and consequently the book was never placed on the Index. Again, the concerns of the experts had concentrated entirely on human evolution.
To reconcile general evolutionary theory with the origin of the human species, with a soul, the concept of "special transformism" was developed, according to which the first humans had evolved by Darwinist processes, up to the point where a soul was added by God to "pre-existent and living matter" (in the words of Pius XII's Humani generis) to form the first fully human individuals; this would normally be considered to be at the point of conception. Léroy's book endorsed this concept; what led to its rejection by the Congregation appears to have been his view that the human species was able to evolve without divine intervention to a fully human state, but lacking only a soul. The theologians felt that some immediate and particular divine intervention was also required to form the physical nature of humans, before the addition of a soul, even if this was worked on near-human hominids produced by evolutionary processes.
The following year, 1896, John Augustine Zahm, a well-known American Holy Cross priest who had been a professor of physics and chemistry at the Catholic University of Notre Dame, Indiana, and was then Procurator General of his Order in Rome, published Evolution and Dogma, arguing that Church teaching, the Bible, and evolution did not conflict. The book was denounced to the Congregation of the Index, who decided to condemn the book but did not publish the corresponding decree, and consequently, the book was never included on the Index. Zahm, who had returned to the United States as Provincial superior of his Order, wrote to his French and Italian editors in 1899, asking them to withdraw the book from the market; however, he never recanted his views. In the meantime his book (in an Italian translation with the imprimatur of Siena) had had a great impact on Geremia Bonomelli, the Bishop of Cremona in Italy, who added an appendix to a book of his own, summarizing and recommending Zahm's views. Bonomelli too was pressured, and retracted his views in a public letter, also in 1898.
Zahm, like St. George Jackson Mivart and his followers, accepted evolution, but not the key Darwinist principle of natural selection, which was still a common position among biologists in general at the time. Another American Catholic author William Seton accepted natural selection also, and was a prolific advocate in the Catholic and general press.
On the Origin of Species was published in 1859, during the papacy of Pope Pius IX, who defined dogmatically papal infallibility during the First Vatican Council in 1869–70. The council has a section on "Faith and Reason" that includes the following on science and faith:
9. Hence all faithful Christians are forbidden to defend as the legitimate conclusions of science those opinions which are known to be contrary to the doctrine of faith, particularly if they have been condemned by the Church; and furthermore they are absolutely bound to hold them to be errors which wear the deceptive appearance of truth. ... 10. Not only can faith and reason never be at odds with one another but they mutually support each other, for on the one hand right reason established the foundations of the faith and, illuminated by its light, develops the science of divine things; on the other hand, faith delivers reason from errors and protects it and furnishes it with knowledge of many kinds.— Vatican Council I
On God the Creator, the First Vatican Council was very clear. The definitions preceding the "anathema" (as a technical term of Catholic theology, let him be "cut off" or excommunicated, cf. Galatians 1:6–9; Titus 3:10–11; Matthew 18:15–17) signify an infallible doctrine of the Catholic Faith (De Fide):
- On God the creator of all things
- If anyone denies the one true God, creator and lord of things visible and invisible: let him be anathema.
- If anyone is so bold as to assert that there exists nothing besides matter: let him be anathema.
- If anyone says that the substance or essence of God and that of all things are one and the same: let him be anathema.
- If anyone says that finite things, both corporal and spiritual, or at any rate, spiritual, emanated from the divine substance; or that the divine essence, by the manifestation and evolution of itself becomes all things or, finally, that God is a universal or indefinite being which by self-determination establishes the totality of things distinct in genera, species and individuals: let him be anathema.
- If anyone does not confess that the world and all things which are contained in it, both spiritual and material, were produced, according to their whole substance, out of nothing by God; or holds that God did not create by his will free from all necessity, but as necessarily as he necessarily loves himself; or denies that the world was created for the glory of God: let him be anathema.
According to Catholic theologian Dr. Ludwig Ott in his 1952 treatise Fundamentals of Catholic Dogma, it is to be understood that these condemnations are of the errors of modern materialism (that matter is all there is), pantheism (that God and the universe are identical), and ancient pagan and gnostic-manichean dualism (where God is not responsible for the entire created world, since mere "matter" is evil not good, see Ott, page 79).
The First Vatican Council also upholds the ability of reason to know God from his creation:
1. The same Holy mother Church holds and teaches that God, the source and end of all things, can be known with certainty from the consideration of created things, by the natural power of human reason: ever since the creation of the world, his invisible nature has been clearly perceived in the things that have been made.— Chapter 2, On Revelation; cf. Romans 1:19–20; and Wisdom chapter 13
Pope Leo XIII, who succeeded in 1878, was known to advocate a more open approach to science, but also to be frustrated by opposition to this within the Vatican and leading church circles, "lamenting on a number of occasions, and not in a particularly private way, the repressive attitudes to scholars exhibited by people around him, and among those he clearly included members of the Civiltà Cattolica college of writers". On one occasion there was "quite a scene when the Pope energetically refused to have the writings of Mons. D'Hulst of Paris put on the Index of Forbidden Books".
Providentissimus Deus, "On the Study of Holy Scripture", was an encyclical issued by Leo XIII on 18 November 1893 on the interpretation of Scripture. It was intended to address the issues arising from both the "higher criticism" and new scientific theories, and their relation with Scripture. Nothing specific concerning evolution was said, and initially both those in favour and against evolution found things to encourage them in the text; however a more conservative interpretation came to be dominant, and the influence of the conservative Jesuit Cardinal Camillo Mazzella (with whom Leo had argued over Mons. D'Hulst) detected. Leo stressed the unstable and changing nature of scientific theory, and criticised the "thirst for novelty and the unrestrained freedom of thought" of the age, but accepted that the apparent literal sense of the Bible might not always be correct. In biblical interpretation, Catholic scholars should not "depart from the literal and obvious sense, except only where reason makes it untenable or necessity requires". Leo stressed that both theologians and scientists should confine themselves to their own disciplines as much as possible.
An earlier encyclical of Leo's on marriage, Arcanum Divinae Sapientiae (1880), had described in passing the Genesis account of the creation of Eve from Adam's side as "what is to all known, and cannot be doubted by any."
The Pontifical Biblical Commission issued a decree ratified by Pope Pius X on June 30, 1909, that stated that the literal historical meaning of the first chapters of Genesis could not be doubted in regard to "the creation of all things by God at the beginning of time; the special creation of man; the formation of the first woman from the first man; the unity of the human race". As in 1860, "special creation" was only referred to in respect of the human species.
The Church does not forbid that ... research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter.
Pope Pius XII's teaching can be summarized as follows:
Some theologians believe Pius XII explicitly excludes belief in polygenism as licit. Another interpretation might be this: As we have nowadays in fact models of thinking of how to reconcile polygenism with the original sin, it need not be condemned. The relevant sentence is this:
Now it is in no way apparent how such an opinion (polygenism) can be reconciled with that which the sources of revealed truth and the documents of the Teaching Authority of the Church propose with regard to original sin, which proceeds from a sin actually committed by an individual Adam and which, through generation, is passed on to all and is in everyone as his own.— Pius XII, Humani generis, 37 and footnote refers to Romans 5:12–19; Council of Trent, Session V, Canons 1–4
In his encyclical Humani generis (1950), my predecessor Pius XII has already affirmed that there is no conflict between evolution and the doctrine of the faith regarding man and his vocation, provided that we do not lose sight of certain fixed points. ... Today, more than a half-century after the appearance of that encyclical, some new findings lead us toward the recognition of evolution as more than a hypothesis. In fact it is remarkable that this theory has had progressively greater influence on the spirit of researchers, following a series of discoveries in different scholarly disciplines. The convergence in the results of these independent studies—which was neither planned nor sought—constitutes in itself a significant argument in favor of the theory.
In the same address, Pope John Paul II rejected any theory of evolution that provides a materialistic explanation for the human soul:
Theories of evolution which, because of the philosophies which inspire them, regard the spirit either as emerging from the forces of living matter, or as a simple epiphenomenon of that matter, are incompatible with the truth about man.
Statements by Cardinal Christoph Schönborn, a close colleague of Benedict XVI, especially a piece in The New York Times on July 7, 2005, appeared to support Intelligent Design, giving rise to speculation about a new direction in the Church's stance on the compatibility between evolution and Catholic doctrine; many of Schönborn's complaints about Darwinian evolution echoed pronouncements originating from the Discovery Institute, an interdenominational Christian think tank. However, Cardinal Schönborn's book Chance or Purpose (2007, originally in German) accepted with certain qualifications the "scientific theory of evolution", but attacked "evolutionism as an ideology", which he said sought to displace religious teaching over a wide range of issues. Nonetheless, in the mid-1980s, Pope Benedict XVI, while serving as Prefect of the Sacred Congregation of the Doctrine of the Faith, wrote a defense of the doctrine of creation against Catholics who stressed the sufficiency of "selection and mutation." Humans, Benedict XVI insisted, are "not the products of chance and error," and "the universe is not the product of darkness and unreason; it comes from intelligence, freedom, and from the beauty that is identical with love."
The Church has deferred to scientists on matters such as the age of the earth and the authenticity of the fossil record. Papal pronouncements, along with commentaries by cardinals, have accepted the findings of scientists on the gradual appearance of life. In fact, the International Theological Commission in a July 2004 statement endorsed by Cardinal Ratzinger, then president of the Commission and head of the Congregation for the Doctrine of the Faith, later Pope Benedict XVI, now Pope Emeritus Benedict XVI, includes this paragraph:
According to the widely accepted scientific account, the universe erupted 15 billion years ago in an explosion called the 'Big Bang' and has been expanding and cooling ever since. Later there gradually emerged the conditions necessary for the formation of atoms, still later the condensation of galaxies and stars, and about 10 billion years later the formation of planets. In our own solar system and on earth (formed about 4.5 billion years ago), the conditions have been favorable to the emergence of life. While there is little consensus among scientists about how the origin of this first microscopic life is to be explained, there is general agreement among them that the first organism dwelt on this planet about 3.5–4 billion years ago. Since it has been demonstrated that all living organisms on earth are genetically related, it is virtually certain that all living organisms have descended from this first organism. Converging evidence from many studies in the physical and biological sciences furnishes mounting support for some theory of evolution to account for the development and diversification of life on earth, while controversy continues over the pace and mechanisms of evolution.
The Church's stance is that any such gradual appearance must have been guided in some way by God, but the Church has thus far declined to define in what way that may be. Commentators tend to interpret the Church's position in the way most favorable to their own arguments. The ITC statement includes these paragraphs on evolution, the providence of God, and "intelligent design":
In freely willing to create and conserve the universe, God wills to activate and to sustain in act all those secondary causes whose activity contributes to the unfolding of the natural order which he intends to produce. Through the activity of natural causes, God causes to arise those conditions required for the emergence and support of living organisms, and, furthermore, for their reproduction and differentiation. Although there is scientific debate about the degree of purposiveness or design operative and empirically observable in these developments, they have de facto favored the emergence and flourishing of life. Catholic theologians can see in such reasoning support for the affirmation entailed by faith in divine creation and divine providence. In the providential design of creation, the triune God intended not only to make a place for human beings in the universe but also, and ultimately, to make room for them in his own trinitarian life. Furthermore, operating as real, though secondary causes, human beings contribute to the reshaping and transformation of the universe.
A growing body of scientific critics of neo-Darwinism point to evidence of design (e.g., biological structures that exhibit specified complexity) that, in their view, cannot be explained in terms of a purely contingent process and that neo-Darwinians have ignored or misinterpreted. The nub of this currently lively disagreement involves scientific observation and generalization concerning whether the available data support inferences of design or chance, and cannot be settled by theology. But it is important to note that, according to the Catholic understanding of divine causality, true contingency in the created order is not incompatible with a purposeful divine providence. Divine causality and created causality radically differ in kind and not only in degree. Thus, even the outcome of a truly contingent natural process can nonetheless fall within God's providential plan for creation.
In addition, while he was the Vatican's chief astronomer, Fr. George Coyne issued a statement on 18 November 2005 saying that "Intelligent design isn't science even though it pretends to be. If you want to teach it in schools, intelligent design should be taught when religion or cultural history is taught, not science." Cardinal Paul Poupard added that "the faithful have the obligation to listen to that which secular modern science has to offer, just as we ask that knowledge of the faith be taken in consideration as an expert voice in humanity." He also warned of the permanent lesson we have learned from the Galileo affair, and that "we also know the dangers of a religion that severs its links with reason and becomes prey to fundamentalism." Fiorenzo Facchini, professor of evolutionary biology at the University of Bologna, called intelligent design unscientific, and wrote in the January 16–17, 2006 edition L'Osservatore Romano: "But it is not correct from a methodological point of view to stray from the field of science while pretending to do science. ...It only creates confusion between the scientific plane and those that are philosophical or religious." Kenneth R. Miller is another prominent Catholic scientist widely known for opposing Young Earth Creationism and Intelligent Design. He writes, concerning Emeritus pope Benedict XVI, that "The Holy Father's concerns are not with evolution per se, but with how evolution is to be understood in our modern world. Biological evolution fits neatly into a traditional Catholic understanding of how contingent natural processes can be seen as part of God's plan ...a careful reading suggests that the new pope will give quarter neither to the enemies of spirituality nor the enemies of evolutionary science. And that's exactly as it should be."
In a commentary on Genesis authored as Cardinal Ratzinger titled In the Beginning... Benedict XVI spoke of "the inner unity of creation and evolution and of faith and reason" and that these two realms of knowledge are complementary, not contradictory:
We cannot say: creation or evolution, inasmuch as these two things respond to two different realities. The story of the dust of the earth and the breath of God, which we just heard, does not in fact explain how human persons come to be but rather what they are. It explains their inmost origin and casts light on the project that they are. And, vice versa, the theory of evolution seeks to understand and describe biological developments. But in so doing it cannot explain where the 'project' of human persons comes from, nor their inner origin, nor their particular nature. To that extent we are faced here with two complementary—rather than mutually exclusive—realities.— Cardinal Ratzinger, In the Beginning: A Catholic Understanding of the Story of Creation and the Fall (Eerdmans, 1995), p. 50.
In a book released in 2008, his comments prior to becoming Pope were recorded as:
The clay became man at the moment in which a being for the first time was capable of forming, however dimly, the thought of "God". The first Thou that—however stammeringly—was said by human lips to God marks the moment in which the spirit arose in the world. Here the Rubicon of anthropogenesis was crossed. For it is not the use of weapons or fire, not new methods of cruelty or of useful activity, that constitute man, but rather his ability to be immediately in relation to God. This holds fast to the doctrine of the special creation of man ... herein ... lies the reason why the moment of anthropogenesis cannot possibly be determined by paleontology: anthropogenesis is the rise of the spirit, which cannot be excavated with a shovel. The theory of evolution does not invalidate the faith, nor does it corroborate it. But it does challenge the faith to understand itself more profoundly and thus to help man to understand himself and to become increasingly what he is: the being who is supposed to say Thou to God in eternity.— Joseph Ratzinger
On September 2–3, 2006 at Castel Gandolfo, Pope Benedict XVI conducted a seminar examining the theory of evolution and its impact on Catholicism's teaching of Creation. The seminar is the latest edition of the annual "Schülerkreis" or student circle, a meeting Benedict has held with his former Ph.D. students since the 1970s. The essays presented by his former students, including natural scientists and theologians, were published in 2007 under the title Creation and Evolution (in German, Schöpfung und Evolution). In Pope Benedict's own contribution he states that "the question is not to either make a decision for a creationism that fundamentally excludes science, or for an evolutionary theory that covers over its own gaps and does not want to see the questions that reach beyond the methodological possibilities of natural science", and that "I find it important to underline that the theory of evolution implies questions that must be assigned to philosophy and which themselves lead beyond the realms of science."
In July 2007 at a meeting with clergy Pope Benedict XVI noted that the conflict between "creationism" and evolution (as a finding of science) is "absurd:" 
Currently, I see in Germany, but also in the United States, a somewhat fierce debate raging between so-called "creationism" and evolutionism, presented as though they were mutually exclusive alternatives: those who believe in the Creator would not be able to conceive of evolution, and those who instead support evolution would have to exclude God. This antithesis is absurd because, on the one hand, there are so many scientific proofs in favour of evolution which appears to be a reality we can see and which enriches our knowledge of life and being as such. But on the other, the doctrine of evolution does not answer every query, especially the great philosophical question: where does everything come from? And how did everything start which ultimately led to man? I believe this is of the utmost importance.
In commenting on statements by his predecessor, he writes "it is also true that the theory of evolution is not a complete, scientifically proven theory." Though commenting that experiments in a controlled environment were limited as "we cannot haul 10,000 generations into the laboratory", he does not endorse Young Earth Creationism or intelligent design. He defends theistic evolution, the reconciliation between science and religion already held by Catholics. In discussing evolution, he writes that "The process itself is rational despite the mistakes and confusion as it goes through a narrow corridor choosing a few positive mutations and using low probability.... This ... inevitably leads to a question that goes beyond science.... Where did this rationality come from?" to which he answers that it comes from the "creative reason" of God.
The 150th anniversary of the publication of the Origin of Species saw two major conferences on evolution in Rome: a five-day plenary session of the Pontifical Academy of Sciences in October/November 2008 on Scientific Insights Into the Evolution of the Universe and of Life and another five-day conference on Biological Evolution: Facts and Theories, held in March 2009 at the Pontifical Gregorian University. These meetings generally confirmed the lack of conflict between evolutionary theory and Catholic theology, and the rejection of Intelligent Design by Catholic scholars.
On October 27, 2014, Pope Francis issued a statement at the Pontifical Academy of Sciences that "Evolution in nature is not inconsistent with the notion of creation," warning against thinking of God's act of creation as "God [being] a magician, with a magic wand able to do everything."
The Pope also expressed in the same statement the view that scientific explanations such as the Big Bang and evolution in fact require God's creation:
[God] created beings and allowed them to develop according to the internal laws that he gave to each one, so that they were able to develop and to arrive at their fullness of being. He gave autonomy to the beings of the universe at the same time at which he assured them of his continuous presence, giving being to every reality. And so creation continued for centuries and centuries, millennia and millennia, until it became what we know today, precisely because God is not a demiurge or a magician, but the creator who gives being to all things. ...The Big Bang, which nowadays is posited as the origin of the world, does not contradict the divine act of creating, but rather requires it. The evolution of nature does not contrast with the notion of creation, as evolution presupposes the creation of beings that evolve.
The Catechism of the Catholic Church (1994, revised 1997) on faith, evolution and science states:
159. Faith and science: "... methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are." (Vatican II GS 36:1)
283. The question about the origins of the world and of man has been the object of many scientific studies which have splendidly enriched our knowledge of the age and dimensions of the cosmos, the development of life-forms and the appearance of man. These discoveries invite us to even greater admiration for the greatness of the Creator, prompting us to give him thanks for all his works and for the understanding and wisdom he gives to scholars and researchers....
284. The great interest accorded to these studies is strongly stimulated by a question of another order, which goes beyond the proper domain of the natural sciences. It is not only a question of knowing when and how the universe arose physically, or when man appeared, but rather of discovering the meaning of such an origin....
Despite these general sections on scientific discussion of the origins of the world and of man, the Catechism does not explicitly discuss the theory of evolution in its treatment of human origins. Paragraph 283 has been noted as making a positive comment regarding the theory of evolution, with the clarification that "many scientific studies" that have enriched knowledge of "the development of life-forms and the appearance of man" refers to mainstream science and not to "creation science".
Concerning the doctrine on creation, Ludwig Ott in his Fundamentals of Catholic Dogma identifies the following points as essential beliefs of the Catholic faith ("De Fide"):
Some Catholic theologians, among them Pierre Teilhard de Chardin, Piet Schoonenberg, and Karl Rahner, have discussed the problem of how evolutionary theory relates to the doctrine of original sin. They generally question the idea of a human fall from an original state of perfection and a common theme among them, most explicitly stated by Rahner, is to see Adam's sin as the sin of the entire human community, which provides a resolution of the problem of polygenism.
Catholic schools in the United States and other countries teach evolution as part of their science curriculum. They teach that evolution occurs and the modern evolutionary synthesis, which is the scientific theory that explains how evolution proceeds. This is the same evolution curriculum that secular schools teach. Bishop Francis X. DiLorenzo of Richmond, chair of the Committee on Science and Human Values, wrote in a letter sent to all U.S. bishops in December 2004: "Catholic schools should continue teaching evolution as a scientific theory backed by convincing evidence. At the same time, Catholic parents whose children are in public schools should ensure that their children are also receiving appropriate catechesis at home and in the parish on God as Creator. Students should be able to leave their biology classes, and their courses in religious instruction, with an integrated understanding of the means God chose to make us who we are."
A survey of principals and teachers of science and of religion at Catholic high schools in the United States indicates some attitudes toward the teaching of evolution and the results of that teaching. 86% of principals reported their schools took an integrated approach to science and religion, in which "evolution, the Big Bang, and the Book of Genesis" were addressed together in classes. On specific topics, 95% of science teachers and 79% of religion teachers agreed that "evolution by natural selection" explains "the diversity of life on earth". Only 21% of science teachers and 32% of religion teachers believed that "Adam and Eve were real historical people". A companion survey of Catholic adults found that 65% of those who had attended a Catholic high school believed in evolution compared to 53% of those who did not attend.
There have been several organizations composed of Catholic laity and clergy which have advocated positions both supporting evolution and opposed to evolution, as well as individual figures such as Bruce Chapman. For example:
Fr. Pierre Teilhard de Chardin, S.J., offers Catholics insight into the relation between Catholic faith and evolution theory. Despite occasional objections to aspects of his thought, Teilhard was never condemned by the magisterial church.
The website "catholic.net", successor to the "Catholic Information Center on the Internet", sometimes features polemics against evolution. Many "traditionalist" organizations are also opposed to evolution, see e.g. the theological journal Living Tradition.
Evolutionary creation best describes the official position of the Roman Catholic Church, though it is often referred to in this tradition as 'theistic evolution.'
From this most primitive form of life, the divinely-guided process of evolution by natural selection brought about higher life forms.
Uniformitarianism has dominated geological thinking since Lyell's time
An influential Roman Catholic cardinal, Cristoph Schonborn, the archbishop of Vienna, appeared to retreat from John Paul II's support for evolution and wrote in The New York Times that descent with modification is a fact, but evolution in the sense of "an unguided, unplanned process of random variation and natural selection" is false. Many of Schonborn's complaints about Darwinian evolution echoed pronouncements originating from the Discovery Institute, the right-wing American think tank that plays a central role in the ID movement (and whose public relations firm submitted Schonborn's article to the Times).
Christoph Schonborn, the Archbishop of Vienna, published an article in The New York Times stating that the declarations made by Pope John Paul II could not be interpreted as recognising evolution. At the same time, he repeated arguments put forward by the supporters of the intelligent design ideas.
Miffed by Krauss's comments, officers at the Discovery Institute arranged for the cardinal archbishop of Vienna, Cristoph Sconborn (b. 1945), to write an op-ed piece for the Times dismissing the late pope's statement as 'rather vague and unimportant' and denying the truth of 'evolution in the neo-Darwinian sense—an unguided, unplanned process of random variation and natural selection.' The cardinal, it seems, had received the backing of the new pope, Benedict XVI, the former Joseph Ratzinger (b. 1927), who in the mid-1980s, while serving as prefect of the Sacred Congregation of the Doctrine of the Faith, successor to the notorious Inquisition, had written a defense of the doctrine of creation against Catholics who stressed the sufficiency of 'selection and mutation.' Humans, he insisted, are 'not the products of chance and error,' and 'the universe is not the product of darkness and unreason. It comes from intelligence, freedom, and from the beauty that is identical with love.' Recent discoveries in microbiology and biochemistry, he was happy to say, had revealed 'reasonable design.'

Most sources of knowledge available to early Christians were connected to pagan world-views. There were various opinions on how Christianity should regard pagan learning, which included its ideas about nature. For instance, among early Christian teachers, Tertullian (c. 160–220) held a generally negative opinion of Greek philosophy, while Origen (c. 185–254) regarded it much more favorably and required his students to read nearly every work available to them.Historically, Christianity has often been a patron of sciences. It has been prolific in the foundation of schools, universities and hospitals, and many clergy have been active in the sciences. Historians of science such as Pierre Duhem credit medieval Catholic mathematicians and philosophers such as John Buridan, Nicole Oresme and Roger Bacon as the founders of modern science. Duhem concluded that "the mechanics and physics of which modern times are justifiably proud to proceed, by an uninterrupted series of scarcely perceptible improvements, from doctrines professed in the heart of the medieval schools".Creationism
Creationism is the religious belief that the universe and life originated "from specific acts of divine creation", as opposed to through natural processes, such as evolution.Creationism covers a spectrum of views including evolutionary creationism, but the term is commonly used for literal creationists who reject various aspects of science, and instead promote pseudoscientific beliefs. Literal creationists base their beliefs on a fundamentalist reading of religious texts, including the creation myths found in Genesis and the Quran. For young Earth creationists, these beliefs are based on a literalist interpretation of the Genesis creation narrative and rejection of the scientific theory of evolution. Literalist creationists believe that evolution cannot adequately account for the history, diversity, and complexity of life on Earth.The first use of the term "creationist" to describe a proponent of creationism is found in an 1856 letter of Charles Darwin describing those who objected on religious grounds to the then-emerging science of evolution.Creation–evolution controversy
The creation–evolution controversy (also termed the creation vs. evolution debate or the origins debate) involves an ongoing, recurring cultural, political, and theological dispute about the origins of the Earth, of humanity, and of other life. Creationism was once widely believed to be true, but since the mid-19th century evolution by natural selection has been established as an empirical scientific fact.
The debate is religious, not scientific: in the scientific community, evolution is accepted as fact and efforts to sustain the traditional view are almost universally regarded as pseudoscience. While the controversy has a long history, today it has retreated to be mainly over what constitutes good science education, with the politics of creationism primarily focusing on the teaching of creationism in public education. Among majority-Christian countries, the debate is most prominent in the United States, where it may be portrayed as part of a culture war. Parallel controversies also exist in some other religious communities, such as the more fundamentalist branches of Judaism and Islam. In Europe and elsewhere, creationism is less widespread (notably, the Catholic Church and Anglican Communion both accept evolution), and there is much less pressure to teach it as fact.Christian fundamentalists repudiate the evidence of common descent of humans and other animals as demonstrated in modern paleontology, genetics, histology and cladistics and those other sub-disciplines which are based upon the conclusions of modern evolutionary biology, geology, cosmology, and other related fields. They argue for the Abrahamic accounts of creation, and, in order to attempt to gain a place alongside evolutionary biology in the science classroom, have developed a rhetorical framework of "creation science". In the landmark Kitzmiller v. Dover, the purported basis of scientific creationism was exposed as a wholly religious construct without formal scientific merit.
The Catholic Church now recognizes the existence of evolution (see Catholic Church and evolution). Pope Francis has stated: "God is not a demiurge or a magician, but the Creator who brought everything to life...Evolution in nature is not inconsistent with the notion of creation, because evolution requires the creation of beings that evolve." The rules of genetic evolutionary inheritance were first discovered by a Catholic priest, the Augustinian monk Gregor Mendel, who is known today as the founder of modern genetics.
According to a 2014 Gallup survey, "More than four in 10 Americans continue to believe that God created humans in their present form 10,000 years ago, a view that has changed little over the past three decades. Half of Americans believe humans evolved, with the majority of these saying God guided the evolutionary process. However, the percentage who say God was not involved is rising." A 2015 Pew Research Center survey found "that while 37% of those older than 65 thought that God created humans in their present form within the last 10,000 years, only 21% of respondents between the ages of 18 and 29 agreed."The debate is sometimes portrayed as being between science and religion, and the United States National Academy of Sciences states:
Today, many religious denominations accept that biological evolution has produced the diversity of living things over billions of years of Earth's history. Many have issued statements observing that evolution and the tenets of their faiths are compatible. Scientists and theologians have written eloquently about their awe and wonder at the history of the universe and of life on this planet, explaining that they see no conflict between their faith in God and the evidence for evolution. Religious denominations that do not accept the occurrence of evolution tend to be those that believe in strictly literal interpretations of religious texts.History of the creation–evolution controversy
The creation–evolution controversy has a long history. In response to theories developed by scientists, some religious individuals and organizations questioned the legitimacy of scientific ideas that contradicted the literal interpretation of the creation account in Genesis. Interpretation of the Judeo-Christian Bible had long been the prerogative of an orthodox priesthood able to understand Latin who traditionally held that Genesis was not meant to be read literally and taught it as an allegory. With the advent of the printing press, the translation of the Bible into other languages, and wider literacy, sundry and more literal understandings of scripture flourished. This allowed some religious persons and groups to challenge scientists who supported evolution, such as biologists Thomas Henry Huxley and Ernst Haeckel.Index of Catholic Church articles

Evolution – change in heritable traits of biological organisms over generations due to natural selection, mutation, gene flow, and genetic drift. Also known as descent with modification. Over time these evolutionary processes lead to formation of new species speciation changes within lineages (anagenesis), and loss of species (extinction). "Evolution" is also another name for evolutionary biology, the subfield of biology concerned with studying evolutionary processes that produced the diversity of life on Earth.Relationship between religion and science
Various aspects of the relationship between religion and science have been cited by modern historians of science and religion, philosophers, theologians, scientists, and others from various geographical regions and cultures. Even though the ancient and medieval worlds did not have conceptions resembling the modern understandings of "science" and "religion", certain elements of these modern ideas are found throughout history. It was in the 19th century when the phrases "religion and science" or "science and religion" first emerged in literature. This coincided with the refining of "science", from the studies of "natural philosophy", and "religion" as distinct concepts in the last few centuries partly due to professionalization of the sciences, the Protestant Reformation, colonization, and globalization. Since then, many have characterized the relationship as either conflict, harmony, complexity, or mutual independence.
Both science and religion are complex social and cultural endeavors that vary across cultures and have changed over time. Most scientific and technical innovations prior to the scientific revolution were achieved by societies organized by religious traditions. Elements of the scientific method were pioneered by ancient pagan, Islamic, and Christian scholars. Roger Bacon, who is often credited with formalizing the scientific method, was a Franciscan friar. Hinduism has historically embraced reason and empiricism, holding that science brings legitimate, but incomplete knowledge of the world and universe. Confucian thought has held different views of science over time. Most Buddhists today view science as complementary to their beliefs. While the classification of the material world by the ancient Indians and Greeks into air, earth, fire and water was more philosophical, medieval Middle Easterns used practical and experimental observation to classify materials.Events in Europe such as the Galileo affair, associated with the scientific revolution and the Age of Enlightenment, led scholars such as John William Draper to postulate a conflict thesis, holding that religion and science have been in conflict methodologically, factually and politically throughout history. This thesis is held by some contemporary scientists such as Richard Dawkins, Lawrence Krauss, Peter Atkins, and Donald Prothero. The conflict thesis has lost favor among most contemporary historians of science.Many scientists, philosophers, and theologians throughout history, such as Francisco Ayala, Kenneth R. Miller and Francis Collins, have seen compatibility or independence between religion and science. Biologist Stephen Jay Gould, other scientists, and some contemporary theologians hold that religion and science are non-overlapping magisteria, addressing fundamentally separate forms of knowledge and aspects of life. Some theologians or historians of science, including John Lennox, Thomas Berry, Brian Swimme and Ken Wilber propose an interconnection between science and religion, while others such as Ian Barbour believe there are even parallels.
Public acceptance of scientific facts may be influenced by religion; many in the United States reject evolution by natural selection, especially regarding human beings. Nevertheless, the American National Academy of Sciences has written that "the evidence for evolution can be fully compatible with religious faith", a view officially endorsed by many religious denominations globally.
