August 18 (August 5 old calendar)

The mother of St. Gregory the Theologian, she was a Christian and a mighty wonderworker through prayer. By her prayers, she brought her husband back from the folly of idolatry to the Christian faith, and he later became bishop of the city of Nazianzus. By her prayers, St. Nonna also saved her son, Gregory the Theologian, from a storm. She entered peacefully into rest as a deaconess in 374.
