Tantum Ergo by St. Thomas Aquinas

Down in adoration falling,Lo, the sacred Host we hail;Lo, o’er ancient forms departing,Newer rights of grace prevailFaith for all defects supplying,Where the feeble senses fail. To the everlasting FatherAnd the Son who reigns on high,With the Spirit still proceedingAge to age eternally,Be salvation, honor, blessing,Might and endless majesty. Tantum ergo SacramentumVeneremur cernuiEt antiquum documentumNovo cedat ritui;Praestet fides supplementum,Sensuum defectui. Genitori GenitoqueLaus et jubilatio,Salus, honor, virtus quoqueSit et benedictio:Procedenti ab utroqueCompar sit laudatio. https://www.youtube.com/watch?v=Swns4Kjzc9E
