He lived for many years as a hermit in the wilderness of the Jordan, and after long and hard ascetic struggle was granted the gift of wonderworking. Once he travelled by ship to Constantinople, and the ship went off course in a storm. The drinking water ran out, and the crew and passengers were near death from thirst. Theodore prayed to God, made the sign of the cross over the sea, and told the crew to drink the seawater. When they did so, they found to their astonishment that it was fresh and sweet. When the people began to honor him, he begged them only to thank God, who had worked the wonder. He reposed in peace.
