Calvin on Justification by Faith Alone

The reader now perceives with what fairness the Sophists of the present day cavil at our doctrine, when we say that a man is justified by faith alone (Rom. 4:2). They dare not deny that he is justified by faith, seeing Scripture so often declares it; but as the word alone is nowhere expressly used they will not tolerate its being added. Is it so? What answer, then will they give to the words of Paul, when he contends that righteousness is not of faith unless it be gratuitous? How can it be gratuitous, and yet by works? By what cavils, moreover, will they evade his declaration in another place, that in the Gospel the righteousness of God is manifested? (Rom. 1:17). If righteousness is manifested in the Gospel, it is certainly not a partial or mutilated, but a full and perfect righteousness. The Law, therefore, has no part in its and their objection to the exclusive word alone is not only unfounded, but is obviously absurd. Does he not plainly enough attribute everything to faith alone when he disconnects it with works? What I would ask, is meant by the expressions, "The righteousness of God without the law is manifested;" "Being justified freely by his grace;" "Justified by faith without the deeds of the law?" (Rom. 3:21, 24, 28). Here they have an ingenious subterfuge, one which, though not of their own devising but taken from Origin and some ancient writers, is most childish. They pretend that the works excluded are ceremonial, not moral works. Such profit do they make by their constant wrangling, that they possess not even the first elements of logic. Do they think the Apostle was raving when he produced, in proof of his doctrine, these passages? "The man that does them shall live in them," (Gal. 3:12). "Cursed is every one that continueth not in all things that are written in the book of the law to do them," (Gal. 3:10). Unless they are themselves raving, they will not say that life was promised to the observers of ceremonies, and the curse denounced only against the transgressors of them. If these passages are to be understood of the Moral Law, there cannot be a doubt that moral works also are excluded from the power of justifying. To the same effect are the arguments which he employs. "By the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin," (Rom. 3:20). "The law worketh wrath," (Rom. 4:15), and therefore not righteousness. "The law cannot pacify the conscience," and therefore cannot confer righteousness. "Faith is imputed for righteousness," and therefore righteousness is not the reward of works, but is given without being due. Because "we are justified by faith," boasting is excluded. "Had there been a law given which could have given life, verily righteousness should have been by the law. But the Scripture has concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe," (Gal. 3:21, 22). Let them maintain, if they dare, that these things apply to ceremonies, and not to morals, and the very children will laugh at their effrontery. The true conclusion, therefore, is, that the whole Law is spoken of when the power of justifying is denied to it. - John Calvin - Institutes of the Christian Religion; 3:11:19
