Peter the Athonite
Saint Peter was born of noble parents in Constantinople in the ninth century. Sent forth with the Roman army against the Saracens, he was taken captive and shut up in the prison of Samarra in Syria; this is no doubt the same prison in which the Forty-Two Martyrs of Amorion were kept (see Mar. 6). Released from prison through the prayers of Saint Nicholas of Myra and Saint Symeon the God-receiver, he fled to Rome, where he became a monk, and later came to the peninsula of Athos, where he lived in a cave as a solitary, suffering many temptations from the evil one, but also enjoying the manifest help of the most holy Theotokos. After many years, he reposed in peace. He is commemorated June 12.
Apolytikion in the Fourth Tone O God of our Fathers, ever dealing with us according to Thy gentleness: take not Thy mercy from us, but by their entreaties guide our life in peace.
Kontakion in the Plagal of the Fourth Tone Having received the noetic and heavenly light in thy heart, O Peter, thou wast seen to be a most radiant vessel of the pure Trinity; and thou didst receive the grace to work miracles, and dost cry: Alleluia
