Maundy Thursday

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 reigns with you and the Holy Spirit, one God, for ever
and ever. Amen.
