Reply to Objection 2: Every deed, in so far as it is done in God's honor, belongs to religion, not as eliciting but as commanding: those belong to religion as eliciting which pertain to the reverence of God by reason of their specific character.
Reply to Objection 3: The object of love is the good, but the object of honor and reverence is something excellent. Now God's goodness is communicated to the creature, but the excellence of His goodness is not. Hence the charity whereby God is loved is not distinct from the charity whereby our neighbor is loved; whereas the religion whereby God is honored, is distinct from the virtues whereby we honor our neighbor.
Whether religion is a theological virtue?
Objection 1: It would seem that religion is a theological virtue. Augustine says (Enchiridion iii) that "God is worshiped by faith, hope and charity," which are theological virtues. Now it belongs to religion to pay worship to God. Therefore religion is a theological virtue.
Objection 2: Further, a theological virtue is one that has God for its object. Now religion has God for its object, since it directs us to God alone, as stated above (A[1]). Therefore religion is a theological virtue.
Objection 3: Further, every virtue is either theological, or intellectual, or moral, as is clear from what has been said (FS, QQ[57],58,62). Now it is evident that religion is not an intellectual virtue, because its perfection does not depend on the consideration of truth: nor is it a moral virtue, which consists properly in observing the mean between too much and too little. for one cannot worship God too much, according to Ecclus. 43:33, "Blessing the Lord, exalt Him as much as you can; for He is above all praise." Therefore it remains that it is a theological virtue.
On the contrary, It is reckoned a part of justice which is a moral virtue.
I answer that, As stated above (A[4]) religion pays due worship to God. Hence two things are to be considered in religion: first that which it offers to God, viz. worship, and this is by way of matter and object in religion; secondly, that to which something is offered, viz. God, to Whom worship is paid. And yet the acts whereby God is worshiped do not reach out to God himself, as when we believe God we reach out to Him by believing; for which reason it was stated (Q[1], AA[1],2,4) that God is the object of faith, not only because we believe in a God, but because we believe God.
Now due worship is paid to God, in so far as certain acts whereby God is worshiped, such as the offering of sacrifices and so forth, are done out of reverence for God. Hence it is evident that God is related to religion not as matter or object, but as end: and consequently religion is not a theological virtue whose object is the last end, but a moral virtue which is properly about things referred to the end.
Reply to Objection 1: The power or virtue whose action deals with an end, moves by its command the power or virtue whose action deals with matters directed to that end. Now the theological virtues, faith, hope and charity have an act in reference to God as their proper object: wherefore, by their command, they cause the act of religion, which performs certain deeds directed to God: and so Augustine says that God is worshiped by faith, hope and charity.
Reply to Objection 2: Religion directs man to God not as its object but as its end.
Reply to Objection 3: Religion is neither a theological nor an intellectual, but a moral virtue, since it is a part of justice, and observes a mean, not in the passions, but in actions directed to God, by establishing a kind of equality in them. And when I say "equality," I do not mean absolute equality, because it is not possible to pay God as much as we owe Him, but equality in consideration of man's ability and God's acceptance.
And it is possible to have too much in matters pertaining to the Divine worship, not as regards the circumstance of quantity, but as regards other circumstances, as when Divine worship is paid to whom it is not due, or when it is not due, or unduly in respect of some other circumstance.
Whether religion should be preferred to the other moral virtues?
Objection 1: It would seem that religion should not be preferred to the other moral virtues. The perfection of a moral virtue consists in its observing the mean, as stated in Ethic. ii, 6. But religion fails to observe the mean of justice, since it does not render an absolute equal to God. Therefore religion is not more excellent than the other moral virtues.
Objection 2: Further, what is offered by one man to another is the more praiseworthy, according as the person it is offered to is in greater need: wherefore it is written ( Is. 57:7 ): "Deal thy bread to the hungry." But God needs nothing that we can offer Him, according to Ps. 15:2, "I have said: Thou art my God, for Thou hast no need of my goods." Therefore religion would seem less praiseworthy than the other virtues whereby man's needs are relieved.
Objection 3: Further, the greater. the obligation to do a thing, the less praise does it deserve, according to 1 Cor. 9:16, "If I preach the Gospel, it is no glory to me: a necessity lieth upon me." Now the more a thing is due, the greater the obligation of paying it. Since, then, what is paid to God by man is in the highest degree due to Him, it would seem that religion is less praiseworthy than the other human virtues.
On the contrary, The precepts pertaining to religion are given precedence ( Ex. 20 ) as being of greatest importance. Now the order of precepts is proportionate to the order of virtues, since the precepts of the Law prescribe acts of virtue. Therefore religion is the chief of the moral virtues.
I answer that, Whatever is directed to an end takes its goodness from being ordered to that end; so that the nearer it is to the end the better it is. Now moral virtues, as stated above (A[5]; Q[4], A[7]), are about matters that are ordered to God as their end. And religion approaches nearer to God than the other moral virtues, in so far as its actions are directly and immediately ordered to the honor of God. Hence religion excels among the moral virtues.
Reply to Objection 1: Virtue is praised because of the will, not because of the ability: and therefore if a man fall short of equality which is the mean of justice, through lack of ability, his virtue deserves no less praise, provided there be no failing on the part of his will.
Reply to Objection 2: In offering a thing to a man on account of its usefulness to him, the more needy the man the more praiseworthy the offering, because it is more useful: whereas we offer a thing to God not on account of its usefulness to Him, but for the sake of His glory, and on account of its usefulness to us.
Reply to Objection 3: Where there is an obligation to do a thing it loses the luster of supererogation, but not the merit of virtue, provided it be done voluntarily. Hence the argument proves nothing.
Whether religion has an external act?
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.
