Prayer of Saint Thomas Aquinas: Ad Sacrosanctum Sacramentum

O sacred banquet at which Christ is consumed, The memory of His Passion recalled, our soul filled with grace, and our pledge of future glory received: How delightful, Lord, is Your spirit, which shows Your sweetness to men, offers the precious bread of heaven, fills the hungry with good things, and sends away empty the scornful rich.

V. You have given them bread from heaven.

R. A bread having all sweetness within it.

Let us pray:

God, Who left for us a memorial of Your Passion in this miraculous sacrament, Grant we implore You, that we may venerate the holy mystery of Your Body and Blood, so that we may ever experience in ourselves the fruitfulness of Your redemption.You who life and reign, world without end.

Amen
