O God, Who by a voice from Heaven didst vouchsafe to summon Thy blessed Confessor Felix from the desert to undertake the work of the ransoming of captives: grant, we beseech Thee, that by Thy grace we may be freed from the bondage of our sins through his intercession and may be guided safely to our Heavenly country. Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, one God, world without end. Amen.
