On prayer and the contemplative life · Aquinas, Saint Thomas
3. Lastly, we are forbidden to pray for others if they are wicked,
Chapter 34 of 107 · 3 min read
according to the words: Do not thou pray for this people ... and do not withstand Me, for I will not hear thee. And, on the other hand, we ought not to pray for them if they are good, for in that case they will be heard when they pray for themselves.
But we have to pray even for sinners, that they may be converted, and for the good, that they may persevere and make progress. Our prayers for sinners, however, are not heard for all, but for some. For they are heard for those who are predestined, not for those who are foreknown as reprobate; just in the same way as when we correct our brethren, such corrections avail among the predestinate but not among the reprobate, according to the words: No man can correct whom He hath despised. Wherefore also it is said: He that knoweth his brother to sin a sin that is not unto death, let him ask, and life shall be given to him who sinneth not to death. But just as we can refuse to no one, as long as he liveth on this earth, the benefit of correction—for we cannot distinguish between the predestinate and the reprobate, as S. Augustine says—so neither can we refuse to anyone the suffrage of our prayers.
And for good men we have to pray, and this for a threefold reason: firstly, because the prayers of many are more easily heard; thus on the words: I beseech ye therefore, help me in your prayers for me, the Ordinary Gloss of S. Ambrose says: "Well does the Apostle ask his inferiors to pray for him; for even the very least become great when many in number, and when gathered together with one mind; and it is impossible that the prayers of many should not avail" to obtain, that is, what is obtainable. And secondly, that thanks may be returned by many for the benefits conferred by God upon the just, for these same benefits tend to the profit of many—as is evident from the Apostle's words to the Corinthians. And thirdly, that those who are greater may not therefore be proud, but may realize that they need the suffrages of their inferiors.
"Father, I will that where I am they also whom Thou hast given Me may be with Me; that they may see My glory, which Thou hast given Me: because Thou hast loved Me before the foundation of the world."

Ought We To Pray for Our Enemies?
But I say to you ... pray for them that persecute and calumniate you.
To pray for others is a work of charity, as we have said above. Hence we are bound to pray for our enemies in the same way as we are bound to love them. We have already explained, in the Treatise on Charity, in what sense we are bound to love our enemies; namely, that we are bound to love their nature, not their fault; and that to love our enemies in general is of precept; to love them, however, individually, is not of precept save in the sense of being prepared to do so; a man, for instance, is bound to be ready to love an individual enemy and to help him in case of necessity, or if he comes to seek his pardon. But absolutely to love our individual enemies, and to assist them, belongs to perfection.
In the same way, then, it is necessary that in our general prayers for others we should not exclude our enemies. But to make special prayer for them belongs to perfection and is not necessary, save in some particular cases.
Some, however, argue that we ought not to pray for our enemies, thus:
