I know you believe Luther was correct in his theology, but there is no amount of verbal gymnastics that will get me to think that way. I’ve read the Bible too and I strongly disagree with him on many points. His Protestant version of Christianity is the most fractured religion on the planet. The largest denomination in the US that bears his name ordains homosexuals. No thanks.
I agree on the last point. I left the Lutheran church in my teens because it was spiritually weak and morally compromised. It had turned liberal. I also tried to convince my folks to leave for the same reason. They resisted, but ultimately saw things that made them agree. Instead of quitting the Lutheran Church entirely, they simply switched to a better Lutheran church. There are several Lutheran denominations, some more conservative than others.
I'm not doing "verbal gymnastics" when I quote Paul who said we are justified by faith in Christ, and not by works. Or don't you know what Paul wrote in Romans?
Rom 3.21 But now apart from the law the righteousness of God has been made known, to which the Law and the Prophets testify. 22 This righteousness is given through faith in Jesus Christ to all who believe.
What Paul was clearly saying is that all the works of the Law, no matter how good, were unable to bring eternal justification and eternal life. God commanded, in the OT, these works of the Law to be done. So it wasn't a bad thing. But they were never intended to bring eternal life, but only to prepare the way for Christ to do the same. They showed human inadequacy without Christ.
So I wouldn't at all say that Paul taught that works under the Law were bad--only that they couldn't save. Furthermore, the failure of the Jews to even obey the Law properly showed the inadequacy of the work of the Law in overcoming the condemnation of sin. Nobody could do the works of the Law perfectly enough to be justified apart from Christ's mercy.
So Paul undeniably said that works of the Law fell short in the matter of eternal justification. And Luther was essentially saying the same thing in his own words. The inadequacy of works of the Law = no salvation without going beyond our works to faith in Christ alone.
I would agree with those who say we must perform works, just as God commanded Israel to do works of the Law. Luther also taught the 10 Commandments as an example of our need to do Christian works. But his point was that works were never perfect enough to bring salvation--only faith in Christ's works could do that!
