The brother of St Basil the Great, he was at first a married priest, but when his wife, the blessed Theosevia, died, he was chosen and consecrated as Bishop of Nyssa. He was distinguished by great secular learning and spiritual experience, and was a great preacher, a translator of the Scriptures and a theologian. As a result of his opposition to the Arians, they did everything in their power to crush him, regarding him as their chief enemy. They were so successful in this that, in the reign of the Emperor Valens, their confederate, they managed to depose him from his episcopal seat and drive him into exile. This was in 376. The holy Father spent several years in patient exile, enduring poverty and humiliation. In 381, he took part in the Second Ecumenical Council, and it is thought that he formulated the final part of the Creed concerning the Holy Spirit. Finally, finishing his life at a great age in about the year 395, he entered into the Kingdom of God and has been commemorated through all succeeding ages as a great light in the Church.
