Saint Peter lived during the reign of the iconoclast Emperor Theophilos (in 829). He was from the province of Galatia in Asia Minor. He was the son of Theophilos and Eudokia and at first he was named Leo.
Because he was handsome, physically strong, and wise, the Emperor made him a count. After many years of war and being in charge of many things, he gave it all up to become a monk in the monastery of Daphne, with the new name Petros.
He went to Olympus, and from there to Jerusalem, but he did not remain there either. After leaving for Laodicia and Antalya, he had to endure arduous journeys, asceticism, and the fierce anger of the Ismaelites (Moslems), whom he encountered in the street. Finally, he returned to Olympus.
Because of the loftiness of his virtues, he began to be noticed by the Emperors. That is why Emperor Basil the Macedonian convinced him to live in the monastery of Saint Phokas in the year 867. After many spiritual struggles, he departed to the Lord in peace.
This Saint Peter should not be confused with another Saint Peter of Galatia who lived in the V century (February 1).
Troparion — Tone 8
By a flood of tears you made the desert fertile, / and your longing for God brought forth fruits in abundance. / By the radiance of miracles you illumined the whole universe! / O our holy father Peter, pray to Christ our God to save our souls!
