O LORD AND MASTER; who hast created man in Thine own likeness, and bestowed upon him the power of life eternal; who also despisest not those who have fallen away through sin, but hast provided salvation for the world through the Incarnation of Thy Christ: Do Thou, the same Lord, delivering also this Thy creature from the bondage of the enemy, receive him into Thy heavenly kingdom. Open the eyes of his understanding, that the illumination of Thy Gospel may shine brightly in him. Assign unto him an angel of light, who shall deliver him from every snare of the adversary, from encounter with evil, from the demon of the noonday, and from evil thoughts.

Expel from him every evil and unclean spirit which hides and makes its lair in his heart, the spirit of deceit, the spirit of evil, the spirit of idolatry and of every covetousness; the spirit of falsehood and of every uncleanness which operates through the prompting of the Devil. And make him a reason-endowed sheep in the holy flock of Thy Christ, an honorable member of Thy Church, a child of the light, and an heir of Thy Kingdom; that having lived in accordance with Thy commandments, and preserved inviolate the Seal, and kept his garment undefiled, he may receive the blessedness of the Saints in Thy Kingdom.

Through the grace and bounties, and love towards mankind of Thine Only-begotten Son, with whom Thou art blessed, together with Thine all-holy and good and life-giving Spirit: now and ever, and unto ages of ages. Amen.
