This, then, is the difference between the legal types and the new and old signs--the former have not attached to them any word of promise requiring faith. Hence they are not signs of justification, for they are not sacraments of the faith that alone justifies, but only sacraments of works; their whole power and nature consisted in works, not in faith, and he that observed them fulfilled them, even if he did it without faith. But our signs, or sacraments, as well as those of the fathers, have attached to them a word of promise, which requires faith, and they cannot be fulfilled by any other work. Hence they are signs or sacraments of justification, for they are the sacraments of justifying faith and not of works. Their whole efficacy, therefore, consists in faith itself, not in the doing of a work; for whoever believes them fulfils them, even if he should not do a single work. Whence has arisen the saying, "Not the sacrament but the faith of the sacrament justifies." Thus circumcision did not justify Abraham and his seed, and yet the Apostle calls it the seal of the righteousness of faith [Rom. 4:11], because faith in the promise, to which circumcision was added, justified him and fulfilled that which circumcision signified. For faith was the spiritual circumcision of the foreskin of the heart [Deut. 10:16; Jer. 4:4], which was symbolised by the literal circumcision of the flesh. And in the same manner it was obviously not Abel's sacrifice that justified him, but it was his faith, by which he offered himself wholly to God and which was symbolised by the outward sacrifice. Even so it is not baptism that justifies or benefits anyone, but it is faith in the word of promise, to which baptism is added. This faith justifies, and fulfils that which baptism signifies. For faith is the submersion of the old man and the emerging of the new. Therefore it cannot be that the new sacraments differ from the old, for both have the divine promise and the same spirit of faith; although they do differ vastly from the olden types on account of the word of promise, which is the one decisive point of difference. Even so, to-day, the outward show of vestments, holy places, meats and of all the endless ceremonies has doubtless a fine symbolical meaning, which is to be spiritually fulfilled; and yet because there is no word of divine promise attached to these things, they can in nowise be compared with the signs of baptism and of the bread, nor do they in any way justify or benefit one, since they are fulfilled in the very observance, apart from faith. For while they are taking place or are being performed, they are being fulfilled; as the Apostle says of them, in Colossians ii, "Which are all to perish with the using, after the commandments and doctrines of men." [Col. 2:22] The sacraments, on the contrary, are not fulfilled when they are observed, but when they are believed.
