Jesus! my Lord, my God, my all!
How can I love Thee as I ought?
And how revere this wondrous gift
So far surpassing hope or thought?
Sweet Sacrament! we thee adore!
Oh, make us love thee more and more!
Had I but Mary's sinless heart
To love Thee with, my dearest King,
Oh, with what bursts of fervent praise
Thy goodness, Jesus, would I sing
Sweet Sacrament, &c.
Oh, see! within a creature's hand
The vast Creator deigns to be,
Reposing infant-like, as though
On Joseph's arm, or Mary's knee.
Sweet Sacrament, &c.
Thy Body, Soul, and Godhead, all!
Oh, mystery of love divine!
I cannot compass all I have;
For all Thou hast and art are mine!
Sweet Sacrament, &c.
He comes! He comes! the Lord of Hosts,
Borne on His throne triumphantly!
We see Thee, and we know Thee, Lord;
And yearn to shed our blood for Thee
Sweet Sacrament, &c.
