St. Basil the Great
O God and Lord of the Powers, and Maker of all creation, Who, because of Thy clemency and incomparable mercy, didst send Thine Only-Begotten Son and our Lord Jesus Christ for the salvation of mankind, and with His venerable Cross didst tear asunder the record of our sins, and thereby didst conquer the rulers and powers of darkness;
Receive from us sinful people, O merciful Master, these prayers of gratitude and supplication, and deliver us from every destructive and gloomy transgression, and from all visible and invisible enemies who seek to injure us.
Nail down our flesh with fear of Thee, and let not our hearts be inclined to words or thoughts of evil, but pierce our souls with Thy love, that ever contemplating Thee, being enlightened by Thee, and discerning Thee, the unapproachable and everlasting Light, we may unceasingly render confession and gratitude to Thee: The eternal Father, with Thine Only-Begotten Son, and with Thine All-Holy, Gracious, and Life-Giving Spirit, now and ever, and unto ages of ages.
