Perhaps you have heard the bells and did not realize what they were for? Almost all the churches that have bells do ring the Angelus, at least at noon and usually at 6pm as well. I believe the reason the bells are not rung at 6am is because of local noise restrictions. One would know the Angelus Bell by a triple stroke, repeated three times with a pause in between.
Many Catholic schools still say the noon Angelus every school day, at least all that I ever taught in or visited. there even are places where the Angelus is broadcast daily, either on T.V. or over the radio. In Ireland, the Phillipines and some parts of Mexico it is televised. In Canada and the U.S there are Catholic radio stations, run by laity, which broadcast daily.
Benediction is basically a short service, consisting mainly with the singing of the hymn, Tantum Ergo, with its prayer, followed by a blessing given to the people by the priest making a sign of the cross above them with the Blessed Sacrament, either contained in a ciborium or a monstrance. The forms are very variable. A common form is the exposition of the Host in a monstrance and its incensation while the song O Salutaris is sung. Tantum Ergo is is sung and the Host is incensed again. The blessing follows in silence then the hymn Holy God We Praise Thy Name.
We have Benediction at my parish every First Friday and the Cathedral in my city has it every Friday at 5pm. It also has it after Vespers on Holy Days of obligation and certain other feast days or special occasions. Benediction isn’t a truly ancient tradition. It began sometime in the 16th century and only became popular in the 18th. As with most other traditional forms of worship that are really basically popular expressions of piety, it was practiced more in certain areas than in others.
Tantum Ergo is my favorite. I haven’t thought about it in years. Tantum Ergo are the first two words of the last verses of the Pange Lingua, written by St. Thomas Aquinas:
Latin text
Tantum ergo Sacramentum
Veneremur cernui:
Et antiquum documentum
Novo cedat ritui:
Praestet fides supplementum
Sensuum defectui.
Genitori, Genitoque
Laus et jubilatio,
Salus, honor, virtus quoque
Sit et benedictio:
Procedenti ab utroque
Compar sit laudatio.
Amen.
V. Panem de caelis[2] praestitisti eis.(T.P. Alleluja)
R. Omne delectamentum in se habentem.(T.P. Alleluja)
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.
R. Amen.
[edit] English translation
Down in adoration falling,
Lo! 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 Spirit proceeding
Forth from each eternally,
Be praise, honor, and blessing,
Might and endless majesty.
Amen.
R. Thou hast given them bread from heaven.
V. Having within it all sweetness.
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.
