Breaking of Bread:

Lamb of God, you take away the sins of the world: have mercy on us. (Repeat)

Lamb of God, you take away the sins of the world: grant us peace. [The next day he saw Jesus coming toward him and said, "Behold, the Lamb of God, who takes away the sin of the world." (John 1:29)]

Communion:

This is the Lamb of God who takes away the sins of the world. Happy are those who are called to his supper. [ . . . Blessed are those who have been called to the wedding feast of the Lamb. (Revelation 19:9)]
Lord, I am not worthy to receive you, but only say the word and I shall be healed. [Lord, I am not worthy to have you enter under my roof, only say the word and my servant will be healed. (Matthew 8:8)]
