In case you were curious about the hymn the Catholic girls sing in Temple of the Holy Ghost:
Tantum Ergo is the last two stanzas from the Eucharistic Hymn (Pange Lingua) composed by St. Thomas Aquinas and is used at Benediction of the Blessed Sacrament. The response and the prayer at the end is a later addition used at Benediction. A partial indulgence is granted to the faithful who recite it and a plenary indulgence is granted to those who recite it on Holy Thursday or Corpus Christi.
| TANTUM ergo Sacramentum Veneremur cernui: Et antiquum documentum Novo cedat ritui: Praestet fides supplementum Sensuum defectui. |
DOWN in adoration falling, Lo! the sacred Host we hail, Lo! oe’r ancient forms departing Newer rites of grace prevail; Faith for all defects supplying, Where the feeble senses fail. |
| Genitori, Genitoque Laus et iubilatio, Salus, honor, virtus quoque Sit et benedictio: Procedenti ab utroque Compar sit laudatio. Amen. |
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. Panem de caelo praestitisti eis. (T.P. Alleluia) R. Omne delectamentum in se habentem. (T.P. Alleluia) |
V. Thou hast given them bread from heaven (P.T. Alleluia). R. Having within it all sweetness (P.T. Alleluia). |
| Oremus: Deus, qui nobis sub sacramento mirabili, passionis tuae memoriam reliquisti: tribue, quaesumus, ita nos corporis et sanguinis tui sacra mysteria venerari, ut redemptionis tuae fructum in nobis iugiter sentiamus. Qui vivis et regnas in saecula saeculorum. | Let us pray: O God, who in this wonderful Sacrament left us a memorial of Thy Passion: grant, we implore Thee, that we may so venerate the sacred mysteries of Thy Body and Blood, as always to be conscious of the fruit of Thy Redemption. Thou who livest and reignest forever and ever. |
| R. Amen. | R. Amen. |
