Canciones Religiosas

St. Thomas Aquinas

Tantum ergo sacramentum
Veneremur cernui
Et antiquum documentum
Novo cedat ritui
Praestet fides supplementum
Sensuum defectui

Genitori, genitoque
Laus et iubilatio
Salus, honor, virtus quoque
Sit et benedictio
Procedenti ab utroque
Compar sit laudatio
Amen
