Gregory of Nyssa, also known as Gregory Nyssen (; c. 335 – c. 395), was Bishop of Nyssa in Cappadocia from 372 to 376 and from 378 until his death in 395. He is venerated as a saint in Catholicism, Eastern Orthodoxy, Oriental Orthodoxy, Anglicanism, and Lutheranism. Gregory, his elder brother Basil of Caesarea, and their friend 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 Christian theologian who made significant contributions to the doctrine of the Trinity and the Nicene Creed. Gregory's philosophical writings were influenced by Origen. Since the mid-twentieth century, there has been a significant increase in interest in Gregory's works from the academic community, particularly involving universal salvation, which has resulted in challenges to many traditional interpretations of his theology. Background The Book of Acts depicts that on the Day of Pentecost there were visiting Jews who were "residents of ...Cappadocia" in attendance. In the First Epistle of Peter, written after AD 65, the author greets Christians who are "exiles scattered throughout…Cappadocia". There is no further reference to Cappadocia in the rest of the New Testament. Early Christianity arose in Cappadocia relatively late, with no evidence of a Christian community before the late second century AD. Alexander of Jerusalem was the first bishop of the province in the early to mid third century, a period in which Christians suffered persecution from the local Roman authorities. The community remained very small throughout the third century: when Gregory Thaumaturgus acceded to the bishopric in c. 250, according to his namesake, the Nyssen, there were only seventeen members of the Church in Caesarea. Cappadocian bishops were among those at the First Council of Nicaea. Because of the broad distribution of the population, rural bishops [χωρεπισκοποι] were appointed to support the Bishop of Caesarea. During the late fourth century there were around 50 of them. In Gregory's lifetime, the Christians of Cappadocia were devout, with the veneration of the Forty Martyrs of Sebaste and Saint George being particularly significant and represented by a considerable monastic presence. There were some adherents of heretical branches of Christianity, most notably Arians, Encratites and Messalians. Biography Early life and education Gregory was born around 335, probably in or near the city of Neocaesarea, Pontus. His family was aristocratic and Christian—according to
