Some sources say that he became a monk in an isolated monastery in Thrace and slept on a rock to reduce his sleep. He often went bareheaded and covered himself with a hair shirt. It is also said that God bestowed upon him the gift of working miracles during his life and after his death and that he died around the year 400 AD.
The church celebrates his feast on April 20.
Troparion for the Bar in Tone 8
For the barren wilderness, with the streams of your tears you watered, and with the sighs from the depths you bore fruit, with your labors a hundredfold, so you became a star for the inhabited world, shining with wonders, O our righteous father Theodore, so intercede with Christ God to save our souls.
