O Sacrum Convivium
O sacred banquet, in which Christ is received, the memory of his Passion is renewed, the mind is filled with grace, and a pledge of future glory is given to us.
Down in adoration falling,
Lo! the sacred Host we hail;
Lo! o’er ancient forms departing,
Newer rites of grace prevail;
Faith for all defects supplying,
Where the feeble senses fail.
To the everlasting Father,
And the Son who reigns on high,
With the Holy Spirit proceeding
Forth from each eternally,
Be salvation, honor, blessing,
Might and endless majesty Amen.
V. You have given them bread from heaven,
R. Having all delight within it.
Let us pray
O God, who in this wonderful Sacrament left us a memorial of your Passion: grant, we implore you, that we may so venerate the sacred mysteries of your Body and Blood, as always to be conscious of the fruit of your Redemption, You who live and reign forever and ever. Amen.
