Of Prayer, by John Calvin, tr. Henry Beveridge , at sacred-texts.com
They again object, Are those, then, to be deprived of every pious wish, who, during the whole course of their lives, breathed nothing but piety and mercy? I have no wish curiously to pry into what they do or meditate; but the probability is, that instead of being subject to the impulse of various and particular desires, they, with one fixed and immoveable will, long for the kingdom of God, which consists not less in the destruction of the ungodly than in the salvation of believers. If this be so, there cannot be a doubt that their charity is confined to the communion of Christ's body, and extends no farther than is compatible with the nature of that communion. But though I grant that in this way they pray for us, they do not, however, lose their quiescence so as to be distracted with earthly cares: far less are they, therefore, to be invoked by us. Nor does it follow that such invocation is to be used because, while men are alive upon the earth, they can mutually commend themselves to each other's prayers. It serves to keep alive a feeling of charity when they, as it were, share each other's wants, and bear each other's burdens. This they do by the command of the Lord, and not without a promise, the two things of primary importance in prayer. But all such reasons are inapplicable to the dead, with whom the Lord, in withdrawing them from our society, has left us no means of intercourse (Eccl. 9:5, 6), and to whom, so far as we can conjecture, he has left no means of intercourse with us. But if any one allege that they certainly must retain the same charity for us, as they are united with us in one faith, who has revealed to us that they have ears capable of listening to the sounds of our voice, or eyes clear enough to discern our necessities? Our opponents, indeed, talk in the shade of their schools of some kind of light which beams upon departed saints from the divine countenance, and in which, as in a mirror, they, from their lofty abode, behold the affairs of men; but to affirm this with the confidence which these men presume to use, is just to desire, by means of the extravagant dreams of our own brain, and without any authority, to pry and penetrate into the hidden judgments of God, and trample upon Scripture, which so often declares that the wisdom of our flesh is at enmity with the wisdom of God, utterly condemns the vanity of our mind, and humbling our reason, bids us look only to the will of God.
