Let us pray to the Lord. Lord, have mercy.
Oh God of our salvation, Son of the living God, Who is borne on the Cherubim, being above all Principalities, Authorities, Powers and Dominions: Thou art great and dreadful unto all them that are around Thee; Thou art He that didst set Heaven as a vault; Thou art He that madest earth in Thy might and didst order the universe in Thy wisdom; Who causest that which is under the heavens to shake from its very foundations, yet its pillars are unshaken; Who speakest unto the sun and it does not shine, and Who sealest the stars; Who interdictest the seas and driest them up; from Whose wrath authorities and powers hide, and the rocks tremble at Thee. Thou hast shattered the gates of brass and hast broken the iron bars. Thou hast bound the mighty one and smashed his vessels; Thou hast cast down the tyrant by Thy Cross and hast drawn out the serpent with the hook of Thy humanity; and having cast him down, Thou hast bound him chains in the gloom of Tartarus. Do Tou Thyself, therefore, O Lord, the Hope of them that have set their confirmation on Thee, and the Wall of strength for them whose expectation is on Thee, renounce, drive away, and put to flight every diabolical action, every satanic invasion, every slander and contrary power lying under this roof, and from them that have been seized by him, and from them that walk about under it, bearing the sign of victory, dreadful against demons, of Thy Cross, and calling upon Thy good name. Yea, O Lord, Who didst drive away a legion of demons, and Who, having restrained the dumb and deaf demon and the unclean spirit, didst command it to depart from the man, and never to return again; Who didst consume the whole army of our invisible enemies, and didst impart wisdom unto the faithful who have known Thee, saying, "Behold, I give unto you power to trample underfoot serpents and scorpions, and over all the power of the enemy" (Luke 10:19). Do Thou Thyself, O Master, keep everyone in this house beyond every harm and temptation, delivering them from the terror of the night, from the arrow that flies by day, from that which walks about in the darkness, from calamity and the demon of noonday. Let Thy servants, Thy handmaidens, and infants, delighting inThy help, and protected by the angelic hosts, cry out in faith, with one accord, "The the Lord is my helper, and I will not fear; what can a man do unto me?" (Psalm 117:6). And again, "I will fear no evil, for Thou art with me" (Psalm 22:4). For Thou, O God, art my Confirmation, Mighty Master, Prince of Peace, Father of the age to come, and Thy Kingdom is an eternal Kingdom. And unto Thee only is the Kingdom, and the Power, and the Glory, together with the Father and the Holy Spirit, now and ever, and unto the ages of ages. Amen.
