Saint Theodora came from pious parents, Antonios and Chrysanthos, who lived on the island of Aegina. Her lifetime coincided with the reign of Emperor Michael, when the holy Church was experiencing turmoil due to the iconoclastic heresy. Theodora entered into marriage and bore a daughter, after which the family relocated to Thessalonica due to the invasion of enemies.
When her daughter reached the age of maturity, Theodora dedicated her to the service of God in a monastery, and after the death of her husband, she took monastic vows in the same monastery. Leading a strict ascetic life, she pleased the Lord with her labors, fasting, and prayer, performing miracles both during her life and after her death.
After her passing, when the abbess of the monastery died, a miracle occurred: the body of Theodora moved, making way for the abbess, which astonished all present. From the holy relics of Theodora, fragrant myrrh flowed, healing the sick and casting out demons to the glory of Christ our God.
On that same day, the memory of the holy fathers Theonas, Simeon, and Forvin is celebrated.
