I answer that, As Augustine says (ad Probam, de orando Deum, Ep. cxxx, 12): "It is lawful to pray for what it is lawful to desire." Now it is lawful to desire temporal things, not indeed principally, by placing our end therein, but as helps whereby we are assisted in tending towards beatitude, in so far, to wit, as they are the means of supporting the life of the body, and are of service to us as instruments in performing acts of virtue, as also the Philosopher states (Ethic. i, 8). Augustine too says the same to Proba (ad Probam, de orando Deum, Ep. cxxx, 6, 7) when he states that "it is not unbecoming for anyone to desire enough for a livelihood, and no more; for this sufficiency is desired, not for its own sake, but for the welfare of the body, or that we should desire to be clothed in a way befitting one's station, so as not to be out of keeping with those among whom we have to live. Accordingly we ought to pray that we may keep these things if we have them, and if we have them not, that we may gain possession of them."
Reply Obj. 1: We should seek temporal things not in the first but in the second place. Hence Augustine says (De Serm. Dom. in Monte ii, 16): "When He says that this" (i.e. the kingdom of God) "is to be sought first, He implies that the other" (i.e. temporal goods) "is to be sought afterwards, not in time but in importance, this as being our good, the other as our need."
Reply Obj. 2: Not all solicitude about temporal things is forbidden, but that which is superfluous and inordinate, as stated above (Q. 55, A. 6).
Reply Obj. 3: When our mind is intent on temporal things in order that it may rest in them, it remains immersed therein; but when it is intent on them in relation to the acquisition of beatitude, it is not lowered by them, but raises them to a higher level.
Reply Obj. 4: From the very fact that we ask for temporal things not as the principal object of our petition, but as subordinate to something else, we ask God for them in the sense that they may be granted to us in so far as they are expedient for salvation. _______________________
SEVENTH ARTICLE [II-II, Q. 83, Art. 7]
Whether We Ought to Pray for Others?
Objection 1: It would seem that we ought not to pray for others. In praying we ought to conform to the pattern given by our Lord. Now in the Lord's Prayer we make petitions for ourselves, not for others; thus we say: "Give us this day our daily bread," etc. Therefore we should not pray for others.
Obj. 2: Further, prayer is offered that it may be heard. Now one of the conditions required for prayer that it may be heard is that one pray for oneself, wherefore Augustine in commenting on John 16:23, "If you ask the Father anything in My name He will give it you," says (Tract. cii): "Everyone is heard when he prays for himself, not when he prays for all; wherefore He does not say simply 'He will give it,' but 'He will give it you.'" Therefore it would seem that we ought not to pray for others, but only for ourselves.
Obj. 3: Further, we are forbidden to pray for others, if they are wicked, according to Jer. 7:16, "Therefore do not then pray for this people . . . and do not withstand Me, for I will not hear thee." On the other hand we are not bound to pray for the good, since they are heard when they pray for themselves. Therefore it would seem that we ought not to pray for others.
