Putting aside childish things for the things of God as a young boy, Saint Peter sought to embrace the eremitic life as soon as he was able. Delayed from doing so after the death of his parents by the responsibility of caring for his younger sister, he achieved his aim when she agreed to enter the monastic life as well. Searching for hesychia, he journeyed to a deserted place where he lived in alone in a cave for many years in fasting and prayer. His only companions were the wild animals who dwelt with him as in an outpost of Paradise. While there, he was continuously assailed by demons who sought to sow despair, but the saint confidently drove them off by chanting psalms and hymns. Seeking yet again to wound the heal of man, the Saint was set upon by a snake, but the Holy Archangel Michael appeared and repulsed the snake with his sword. In thankfulness for this protection, Saint Peter increased his ascetic efforts. This resulted in such a deeply Christ-like transformation that he was able to discern the pits the demons continuously dug for him, avoiding them with prayer and humility. He continuously reminded himself that he had been created from the dust of the earth and that he could do nothing without God’s help. The prince of the power of the air, however, would not relent, attacking him with a flock of crows that tried to bend him by pecking out his eyes. This time, the Saint again put him to flight by prayer, specifically the recitation of the Creed. In the end, his victory was proclaimed by the Lord Himself, the uncreated light filling his cave for a number of days. This abundant grace led to his discovery by other monks. He handed down to them his teaching on the ascetic life before falling asleep in peace, having recapitulated the life of mankind in salvation as a co-worker with Christ.
