We shall now cite passages which clearly state, that by faith we are made pious and righteous—not that our faith is a work so precious and pure, but solely because by faith, and by no other means, we receive the mercy offered.
In the Epistle to the Romans, Paul treats particularly of the manner in which we are justified before God; and arrives at the conclusion, that all those who believe that God is merciful to them through Christ, are justified before God by faith, without merit. And this forcible conclusion, this proposition, in which is comprehended the main subject of the whole epistle, yea, of all the Scriptures, he lays down clearly and unequivocally in the third chapter to the Romans and the 28th verse, “Therefore we conclude that a man is justified by faith without the deeds of the law.”
Our adversaries here contend, that Paul excluded only the Jewish ceremonies, not other virtuous works. Paul, however, does not speak of ceremonies only, but properly and assuredly of all other works, and of the whole law, or Ten Commandments. For in the 7th verse of the 7th chapter he afterwards quotes the passage from the Decalogue, “Thou shalt not covet.”
