Cappadocian Fathers

The Cappadocian Fathers, also traditionally known as the Three Cappadocians, are Basil the Great (330–379), who was bishop of Caesarea; Basil's younger brother Gregory of Nyssa (c. 335 – c. 395), who was bishop of Nyssa; and a close friend, Gregory of Nazianzus (329–389), who became Patriarch of Constantinople. The Cappadocia region, in modern-day Turkey, was an early site of Christian activity, with several missions by Paul in this region.

The Cappadocians advanced the development of early Christian theology, for example the doctrine of the Trinity,^: 22 and are highly respected as saints in both Western and Eastern churches.
