Lamb of God, who takes away the sin of the world, look on us and have mercy on us, you who are both victim and priest, reward and redeemer; keep safe from all evils those whom you have redeemed, O Savior of the world. ((Old Gallican Missal, Thomas C. Oden and Cindy Crosby, eds., Ancient Christian Devotional: A Year of Weekly Readings: Lectionary Cycle A (Downers Grove, IL: IVP Books, 2007), 105.))
