O God, you willed to redeem us from all iniquity by your Son: Deliver us when we are tempted to regard sin without abhorrence, and let the virtue of his passion come between us and our mortal enemy; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
