Whether the prayers which the saints pour forth to God for us are always granted?

Objections

Objection 1 : It would seem that the prayers which the saints pour forth to God for us are not always granted. For if they were always granted, the saints would be heard especially in regard to matters concerning themselves. But they are not heard in reference to these things; wherefore it is stated in the Apocalypse (6:11) that on the martyrs beseeching vengeance on them that dwell on earth, "it was said to them that they should rest for a little while till the number of their brethren should be filled up [*Vulg.: 'till their fellow-servants and their brethren . . . should be filled up']." Much less therefore, are they heard in reference to matters concerning others.
Objection 2 : Further, it is written (Jer. 15:1): "If Moses and Samuel shall stand before Me, My soul is not towards this people." Therefore, the saints are not always heard when they pray God for us.
Objection 3 : Further, the saints in heaven are stated to be equal to the angels of God (Mt. 22:30). But the angels are not always heard in the prayers which they offer up to God. This is evident from Dan. 10:12,13, where it is written: "I am come for thy words: but the prince of the kingdom of the Persians resisted me one-and-twenty days." But the angel who spoke had not come to Daniel's aid except by asking of God to be set free; and yet the fulfillment of his prayer was hindered. Therefore neither are other saints always heard by God when they pray for us.
Objection 4 : Further, whosoever obtains something by prayer merits it in a sense. But the saints in heaven are not in the state of meriting. Therefore they cannot obtain anything for us from God by their prayers.
Objection 5 : Further, the saints, in all things, conform their will to the will of God. Therefore they will nothing but what they know God to will. But no one prays save for what he wills. Therefore they pray not save for what they know God to will. Now that which God wills would be done even without their praying for it. Therefore their prayers are not efficacious for obtaining anything.
Objection 6 : Further, the prayers of the whole heavenly court, if they could obtain anything, would be more efficacious than all the petitions of the Church here below. Now if the suffrages of the Church here below for some one in purgatory were to be multiplied, he would be wholly delivered from punishment. Since then the saints in heaven pray for those who are in purgatory on the same account as for us, if they obtain anything for us, their prayers would deliver entirely from punishment those who are in purgatory. But this is not true because, then the Church's suffrages for the dead would be unnecessary.
