The doctrine of faith alone was written by a Jewish follower of Christ.
Perhaps you've heard of him? His name was Paul.
28For we maintain that a man is justified by faith apart from works of the Law. 29Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, 30since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one.
Again, and I really hope you can understand this....I am a follower of the Jewish carpenter from Nazareth, Jesus Christ.
You cannot be anti-semittic and be a follower of Jesus.
The question still begs to be answered by you....are you a follower of Jesus?
Are you relying upon Him and Him alone for your salvation?
Jesus makes it clear that faith is through Him and only Him in John 14:6...."I am the way, the truth and the life...."
Was Luther "a follower of Jesus ?"
I'm sorry, but I just don't believe you follow Christ. Otherwise, you would not reject His Church, the one and only Church, that He founded.
