Collect

Lord Jesus Christ,
we thank you that in this wonderful sacrament
you have given us the memorial of your passion:
grant us so to reverence the sacred mysteries
of your body and blood
that we may know within ourselves
and show forth in our lives
the fruits of your redemption;
for you are alive and reign with the Father
in the unity of the Holy Spirit,
one God, now and for ever.

Post Communion

All praise to you, our God and Father,
for you have fed us with the bread of heaven
and quenched our thirst from the true vine:
hear our prayer that, being grafted into Christ,
we may grow together in unity
and feast with him in his kingdom;
through Jesus Christ our Lord.
