Whether adoration is an act of latria or religion?

Objections

Objection 1 : It would seem that adoration is not an act of latria or religion. The worship of religion is due to God alone. But adoration is not due to God alone: since we read (Gn. 18:2) that Abraham adored the angels; and (3 Kgs. 1:23) that the prophet Nathan, when he was come in to king David, "worshiped him bowing down to the ground." Therefore adoration is not an act of religion.
Objection 2 : Further, the worship of religion is due to God as the object of beatitude, according to Augustine (De Civ. Dei x, 3): whereas adoration is due to Him by reason of His majesty, since a gloss on Ps. 28:2, "Adore ye the Lord in His holy court," says: "We pass from these courts into the court where we adore His majesty." Therefore adoration is not an act of latria.
Objection 3 : Further, the worship of one same religion is due to the three Persons. But we do not adore the three Persons with one adoration, for we genuflect at each separate invocation of Them [*At the adoration of the Cross, on Good Friday]. Therefore adoration is nol an act of latria.
