The Nun Pelagia was converted to Christianity by Saint Nonnos, Bishop of Edessa.
Before her acceptance of saving Baptism, Pelagia was head of a dance troupe in Palestinian Antioch, living life in frivolity and profligacy.
But one time Pelagia, elegantly dressed, was making her way past a church, at the doors of which Saint Nonnos was preaching a sermon. Believers turned their faces away from the sinner, but the bishop long glanced after her. Struck by the outer beauty of Pelagia and having foreseen the spiritual greatness in her, the saint in his cell prayed long to the Lord for the sinner, grieving that the poverty attiring his soul could not compare with the splendid garb and beauty of the profligate.
On the following day, when Saint Nonnos was teaching in the church about the Dread Last Judgement and its consequences, Pelagia came. The teaching made such an impression upon her, that betaken with the fear of God and bursting out in tears of repentance, she besought the saint for Baptism. Seeing the sincere and full repentance of Pelagia, Bishop Nonnos baptised her.
By night the devil appeared to Pelagia, urging her to return to her former life. In answer to this the saint made prayer, signed herself with the Sign of the Cross, and the devil vanished. Having gathered up her valuables, Saint Pelagia took them to Bishop Nonnos. The bishop gave orders to distribute it amidst the poor with the words: “Let be wisely dispersed what is miraculously gathered.”
After this Saint Pelagia in hair-shirt journeyed to Jerusalem to the Mount of Olives. There, until her end (457), she asceticised in seclusion under the masculine name Pelagios, and attained to great spiritual gifts.
