Almighty Father, whose dear Son, on the night before he suffered, instituted the Sacrament of his Body and Blood: Mercifully grant that we may receive it thankfully in remembrance of Jesus Christ our Lord, who in these holy mysteries gives us a pledge of eternal life; and who now lives and reigneth with thee and the Holy Spirit, one God, for ever and ever. Amen.
