Whether religion has an external act?

Objections

Objection 1 : It would seem that religion has not an external act. It is written (Jn. 4:24): "God is a spirit, and they that adore Him, must adore Him in spirit and in truth." Now external acts pertain, not to the spirit but to the body. Therefore religion, to which adoration belongs, has acts that are not external but internal.
Objection 2 : Further, the end of religion is to pay God reverence and honor. Now it would savor of irreverence towards a superior, if one were to offer him that which properly belongs to his inferior. Since then whatever man offers by bodily actions, seems to be directed properly to the relief of human needs, or to the reverence of inferior creatures, it would seem unbecoming to employ them in showing reverence to God.
Objection 3 : Further, Augustine (De Civ. Dei vi, 10) commends Seneca for finding fault with those who offered to idols those things that are wont to be offered to men, because, to wit, that which befits mortals is unbecoming to immortals. But such things are much less becoming to the true God, Who is "exalted above all gods" [*Ps. 94:3]. Therefore it would seem wrong to worship God with bodily actions. Therefore religion has no bodily actions.
