St. Gregory is the brother of St. Basil the Great and St. Macrina. He served as a priest while married to his wife, Theosebia. The Prologue says that he was consecrated Bishop of Nyssa after being widowed. Some accounts say that they each voluntarily became monastics. Some accounts know of a definite close relationship between the two of them and assume that she was his sister. Gregory was a gifted scholar and translator of the Scriptures. He was a chief opponent to the Arian heresy. The Arians had Emperor Valens depose Gregory in 376, so he spent several years in exile. In 381, he took part in the 2nd Ecumenical Council. Many credit him with formulating the final part of the Creed concerning the Holy Spirit. He reposed in 395.<\/p>\n
