Whether devotion is an act of religion?

Objections

Objection 1 : It would seem that devotion is not an act of religion. Devotion, as stated above (Article [1]), consists in giving oneself up to God. But this is done chiefly by charity, since according to Dionysius (Div. Nom. iv) "the Divine love produces ecstasy, for it takes the lover away from himself and gives him to the beloved." Therefore devotion is an act of charity rather than of religion.
Objection 2 : Further, charity precedes religion; and devotion seems to precede charity; since, in the Scriptures, charity is represented by fire, while devotion is signified by fatness which is the material of fire [*Cant. 8:6; Ps. 52:6]. Therefore devotion is not an act of religion.
Objection 3 : Further, by religion man is directed to God alone, as stated above (Question [81], Article [1]). But devotion is directed also to men; for we speak of people being devout to certain holy men, and subjects are said to be devoted to their masters; thus Pope Leo says [*Serm. viii, De Pass. Dom.] that the Jews "out of devotion to the Roman laws," said: "We have no king but Caesar." Therefore devotion is not an act of religion.
