Gregory of Nyssa, also known as Gregory Nyssen (c. 335 – c. 395), was bishop of Nyssa from 372 to 376 and from 378 until his death. He is venerated as a saint in Roman Catholicism, Eastern Orthodoxy, Oriental Orthodoxy, Lutheranism, and Anglicanism. Gregory, his brother, Basil of Caesarea, and Gregory of Nazianzus are collectively known as the Cappadocian Fathers Gregory lacked the administrative ability of his brother Basil or the contemporary influence of Gregory of Nazianzus, but he was an erudite theologian who made significant contributions to the doctrine of the Trinity and the Nicene creed. Gregory's philosophical writings were influenced by Origen, and he is generally considered to have believed in universal salvation. Since the mid-twentieth century, there has been a significant increase in interest in Gregory's works from the academic community, which has resulted in challenges to many traditional interpretations of his theology.
