Of Prayer, by John Calvin, tr. Henry Beveridge , at sacred-texts.com
In regard to the saints who having died in the body live in Christ, if we attribute prayer to them, let us not imagine that they have any other way of supplicating God than through Christ who alone is the way, or that their prayers are accepted by God in any other name. Wherefore, since the Scripture calls us away from all others to Christ alone, since our heavenly Father is pleased to gather together all things in him, it were the extreme of stupidity, not to say madness, to attempt to obtain access by means of others, so as to be drawn away from him without whom access cannot be obtained. But who can deny that this was the practice for several ages, and is still the practice, wherever Popery prevails? To procure the favour of God, human merits are ever and anon obtruded, and very frequently while Christ is passed by, God is supplicated in their name. I ask if this is not to transfer to them that office of sole intercession which we have above claimed for Christ? Then what angel or devil ever announced one syllable to any human being concerning that fancied intercession of theirs? There is not a word on the subject in Scripture. What ground then was there for the fiction? Certainly, while the human mind thus seeks help for itself in which it is not sanctioned by the word of God, it plainly manifests its distrust (see s. 27). But if we appeal to the consciences of all who take pleasure in the intercession of saints, we shall find that their only reason for it is, that they are filled with anxiety, as if they supposed that Christ were insufficient or too rigorous. By this anxiety they dishonour Christ, and rob him of his title of sole Mediator, a title which being given him by the Father as his special privilege, ought not to be transferred to any other. By so doing they obscure the glory of his nativity and make void his cross; in short, divest and defraud of due praise everything which he did or suffered, since all which he did and suffered goes to show that he is and ought to be deemed sole Mediator. At the same time, they reject the kindness of God in manifesting himself to them as a Father, for he is not their Father if they do not recognize Christ as their brother. This they plainly refuse to do if they think not that he feels for them a brother's affection; affection than which none can be more gentle or tender. Wherefore Scripture offers him alone, sends us to him, and establishes us in him. "He," says Ambrose, "is our mouth by which we speak to the Father; our eye by which we see the Father; our right hand by which we offer ourselves to the Father. Save by his intercession neither we nor any saints have any intercourse with God" (Ambros. Lib. de Isaac et Anima). If they object that the public prayers which are offered up in churches conclude with the words, through Jesus Christ our Lord, it is a frivolous evasion; because no less insult is offered to the intercession of Christ by confounding it with the prayers and merits of the dead, than by omitting it altogether, and making mention only of the dead. Then, in all their litanies, hymns, and proses where every kind of honour is paid to dead saints, there is no mention of Christ.
