The Three Cappadocians are three important theologians in the 4th Century AD. They were Basil of Caesarea, Gregory of Nyssa and Gregory of Nazianzus. Their biggest contributions were on the doctrine of the Trinity.

Gregory of Nazianzus wrote that man "has been ordered to become God." This article explores the meaning of these words. This idea of theosis or deification is a distinctive feature of Orthodox theology in the east.
