Tantum Ergo
Tantum Ergo Sacramentum
English Formula
Down in adoration falling, 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 Ghost proceeding forth from Each eternally, be salvation, honor, blessing, might and endless majesty. Amen.
