Sabina Catharina was the eldest child of Count Enno III of East Frisia and his first wife, Countess Walburgis of Rietberg. In the Treaty of Berum of 28 January, the lands her father had inherited from her mother were divided between Sabina Catherine and her sister Agnes, because their father wanted to marry again. Sabina Catherine was awarded the County of Rietberg.
On 3 March 1601, Sabina married her uncle, John III, in a ceremony officiated by Abbot Leonard Ruben of Abdinghof Abbey. The necessary papal dispensation was issued on 13 April 1600. Before the wedding the couple converted to the Catholic faith. In 1618, the couple laid the foundation for the Franciscan monastery in Rietberg. The founding document of the monastery was issued in 1629.
