It is likewise false and untrue, that a man can become righteous and pious before God by his own works and by external piety.

It is unfounded and false, that human reason is able of itself to love God above all things, to keep his commandments, to fear him, to be assured that he hears our prayers, to thank and obey him in afflictions, and in other things enjoined in his law, such as, not to covet the goods of others, &c. For all this, human reason is not able to accomplish, although it can in some degree produce an honorable life externally, and perform good works.

To say that those are without sin, who keep God’s commandments externally only, without the Spirit and grace in their hearts, is also untrue and deceptive, and a blasphemy against Christ.

This conclusion is attested, not only by the holy Scriptures, but also by the ancient Fathers. Augustine treats of this subject largely, in contending against the Pelagians, that grace is not given on account of our own merits. And in his book on Nature and Grace, (de Natura et Gratia,) he says: “If our natural strength is sufficient, by freewill, both to teach us how to live, and how to live aright, then Christ died in vain.”

Why should I not here exclaim with Paul, Gal. 5:4, Rom. 10:3–4? yea, I may justly exclaim with him: “Christ is become of no effect unto you, whosoever of you are justified by the law: ye are fallen from grace.” “For they, being ignorant of God’s righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.” For as Christ is the end of the law, so also is Christ the saviour of corrupted nature. Again, John 8:36: “If the Son therefore shall make you free, ye shall be free indeed.”

Therefore we cannot become free from our sins, or merit their remission, through reason or good works. Again, it is written, John 3:5: “Except a man be born of water, and of the Spirit, he cannot enter into the kingdom of God.” (Henkel Translation, p. 162).

Thus our adversaries teach nothing but the external piety of external good works, which Paul calls the piety of the law; and thus, like the Jews, they see the veiled face of Moses, only strengthening security and hardness of heart in some hypocrites; they lead men upon a sandy foundation, upon their own works, by which means Christ and the Gospel are despised, and give many miserable consciences cause for despair; for they do good works relying upon false conceits, and, never experiencing the great power of faith, they at last sink into despair.

We, however, hold and assert of external piety, that God requires and demands such an external correct life; and that on account of God’s commandment, we must perform the good works prescribed in the Ten Commandments. For the law is our schoolmaster, Gal. 3:24, and is given for the unrighteous. It is the will of the Lord, our God, that gross sins should be restrained by external discipline; and for this purpose, he has given laws, established governments, provided men of learning and wisdom, who are fitted to govern. Human reason can, to some extent, by its own powers, produce an honorable external deportment like this; although it is often hindered in doing so, by innate weakness and the arts of the devil.

Now, although I am willing to allow to this external life and such good works, all the praise that is properly due them;—for in this life and in worldly matters, there is nothing better than honesty and virtue, as Aristotle says: “Neither the morning nor the evening star is more lovely and beautiful than honesty and righteousness,” God himself rewarding such virtues with temporal gifts;—yet, we should not extol good works and such a deportment so as to bring contumely on Christ. The opinion that we must merit the remission of our sins by our works, is certainly a fiction and an error. (Henkel Translation, p. 161-162).
