O Lord God Almighty,
I beseech Thee by the Precious
Body and Blood of Thy Divine Son Jesus,
which He Himself on the night before His Passion
gave as meat and drink to His beloved Apostles
and bequeathed to His Holy Church
to be the perpetual Sacrifice
and life-giving nourishment of His faithful people,
deliver the souls in purgatory,
but most of all,
that soul which was most devoted
to this Mystery of infinite love,
in order that it may praise Thee therefor,
together with Thy Divine Son
and the Holy Spirit in Thy glory for ever.
Amen.
