The Principal Question In the Controversy concerning Good Works.
Concordia Triglotta, 1921 English text
1 Concerning the doctrine of good works two divisions have arisen in some churches:
2 1. First, some theologians have become divided because of the following expressions, where the one side wrote: Good works are necessary for salvation. It is impossible to be saved without good works. Also: No one has ever been saved without good works. But the other side, on the contrary, wrote: Good works are injurious to salvation.
3 2. Afterwards a schism arose also between some theologians with respect to the two words necessary and free, since the one side contended that the word necessary should not be employed concerning the new obedience, which, they say, does not flow from necessity and coercion, but from a voluntary spirit. The other side insisted on the word necessary, because, they say, this obedience is not at our option, but regenerate men are obliged to render this obedience.
4 From this disputation concerning the terms a controversy afterwards occurred concerning the subject itself; for the one side contended that among Christians the Law should not be urged at all, but men should be exhorted to good works from the Holy Gospel alone; the other side contradicted this.
