Whether prayer is an act of religion?

Objections

Objection 1 : It would seem that prayer is not an act of religion. Since religion is a part of justice, it resides in the will as in its subject. But prayer belongs to the intellective part, as stated above (Article [1]). Therefore prayer seems to be an act, not of religion, but of the gift of understanding whereby the mind ascends to God.
Objection 2 : Further, the act of "latria" falls under a necessity of precept. But prayer does not seem to come under a necessity of precept, but to come from the mere will, since it is nothing else than a petition for what we will. Therefore prayer seemingly is not an act of religion.
Objection 3 : Further, it seems to belong to religion that one "offers worship end ceremonial rites to the Godhead" [*Cicero, Rhet. ii, 53]. But prayer seems not to offer anything to God, but to. ask to obtain something from Him. Therefore prayer is not an act of religion.
