A popular Catholic service is Benediction of the Blessed Sacrament.
It is ordinarily an afternoon or evening devotion and consists in the singing of certain hymns, or litanies, or canticles, before the Blessed Sacrament, which is exposed upon the altar in a monstrance and is surrounded with numerous lighted candles.
Incense is frequently used during Benediction service.
At the end, the priest or deacon, his shoulders enveloped in a humeral veil, takes the monstrance into his hands and with it makes the sign of the cross (hence the name Benediction) in silence over the congregation.
Benediction is often employed as a conclusion to other services such as Evening Prayer, but it is also treated as a rite complete in itself. (7:21)
