On the contrary, It is written (James 5:16): "Pray one for another, that you may be saved."
I answer that, As stated above (A. 6), when we pray we ought to ask for what we ought to desire. Now we ought to desire good things not only for ourselves, but also for others: for this is essential to the love which we owe to our neighbor, as stated above (Q. 25, AA. 1, 12; Q. 27, A. 2; Q. 31, A. 1). Therefore charity requires us to pray for others. Hence Chrysostom says (Hom. xiv in Matth.) [*Opus Imperfectum, falsely ascribed to St. John Chrysostom]: "Necessity binds us to pray for ourselves, fraternal charity urges us to pray for others: and the prayer that fraternal charity proffers is sweeter to God than that which is the outcome of necessity."
Reply Obj. 1: As Cyprian says (De orat. Dom.), "We say 'Our Father' and not 'My Father,' 'Give us' and not 'Give me,' because the Master of unity did not wish us to pray privately, that is for ourselves alone, for He wished each one to pray for all, even as He Himself bore all in one."
Reply Obj. 2: It is a condition of prayer that one pray for oneself: not as though it were necessary in order that prayer be meritorious, but as being necessary in order that prayer may not fail in its effect of impetration. For it sometimes happens that we pray for another with piety and perseverance, and ask for things relating to his salvation, and yet it is not granted on account of some obstacle on the part of the person we are praying for, according to Jer. 15:1, "If Moses and Samuel shall stand before Me, My soul is not towards this people." And yet the prayer will be meritorious for the person who prays thus out of charity, according to Ps. 34:13, "My prayer shall be turned into my bosom, i.e. though it profit them not, I am not deprived of my reward," as the gloss expounds it.
Reply Obj. 3: We ought to pray even for sinners, that they may be converted, and for the just that they may persevere and advance in holiness. Yet those who pray are heard not for all sinners but for some: since they are heard for the predestined, but not for those who are foreknown to death; even as the correction whereby we correct the brethren, has an effect in the predestined but not in the reprobate, according to Eccles. 7:14, "No man can correct whom God hath despised." Hence it is written (1 John 5:16): "He that knoweth his brother to sin a sin which is not to death, let him ask, and life shall be given to him, who sinneth not to death." Now just as the benefit of correction must not be refused to any man so long as he lives here below, because we cannot distinguish the predestined from the reprobate, as Augustine says (De Correp. et Grat. xv), so too no man should be denied the help of prayer.
We ought also to pray for the just for three reasons: First, because the prayers of a multitude are more easily heard, wherefore a gloss on Rom. 15:30, "Help me in your prayers," says: "The Apostle rightly tells the lesser brethren to pray for him, for many lesser ones, if they be united together in one mind, become great, and it is impossible for the prayers of a multitude not to obtain" that which is possible to be obtained by prayer. Secondly, that many may thank God for the graces conferred on the just, which graces conduce to the profit of many, according to the Apostle (2 Cor. 1:11). Thirdly, that the more perfect may not wax proud, seeing that they find that they need the prayers of the less perfect. _______________________
EIGHTH ARTICLE [II-II, Q. 83, Art. 8]
Whether We Ought to Pray for Our Enemies?
Objection 1: It would seem that we ought not to pray for our enemies. According to Rom. 15:4, "what things soever were written, were written for our learning." Now Holy Writ contains many imprecations against enemies; thus it is written (Ps. 6:11): "Let all my enemies be ashamed and be . . . troubled, let them be ashamed and be troubled very speedily [*Vulg.: 'Let them be turned back and be ashamed.']." Therefore we too should pray against rather than for our enemies.
Obj. 2: Further, to be revenged on one's enemies is harmful to them. But holy men seek vengeance of their enemies according to Apoc. 6:10, "How long . . . dost Thou not . . . revenge our blood on them that dwell on earth?" Wherefore they rejoice in being revenged on their enemies, according to Ps. 57:11, "The just shall rejoice when he shall see the revenge." Therefore we should not pray for our enemies, but against them.
