Almighty and eternal God,
we thank you for your divine mercy
in giving us
the body and blood
of your only beloved Son
to eat and to drink.
Send your Holy Spirit
to work in us,
so that as we have received
this holy Sacrament
with our mouths and hearts,
we may also receive your divine grace,
forgiveness of sins,
unity with Christ,
and that we may hold on to eternal life
with a steadfast faith
and keep it forever;
through your Son,
Jesus Christ our Lord,
who lives and reigns
with you and the Holy Spirit,
one true God,
forever and ever.
Amen.
