Jesus instituted the Eucharist on Maundy Thursday. The following Maundy Thursday prayer may be said on Maundy Thursday or anytime in which a person feels like offering thanks and praise, or reflecting on the Last Supper/Eucharist.
On the night before he was to give himself up to die
for the salvation of the world,
Our Lord Jesus Christ
gave you thanks and praise,
by celebrating communion with his followers.
Accept this prayer, O Lord,
as a sign of my thanks and praise,
and may you draw me ever closer to you,
through the body and blood of your Son.
I pray in his name. Amen.
