Luther inherited his Bible from the Catholic Church. And then he promptly eliminated several books from it. He had that much respect for the Bible.
Sometimes, he added stuff to the Bible, too.
"Romans 3:28 [Open in Logos Bible Software (if available)] states, "Therefore we conclude that a man is justified by faith apart from the deeds of the law" (NKJV). Martin Luther, in his German translation of the Bible, specifically added the word "allein" (English 'alone') to Romans 3:28 [Open in Logos Bible Software (if available)] -a word that is not in the original Greek. Martin Luther reportedly said, "You tell me what a great fuss the Papists are making because the word alone in not in the text of Paul…say right out to him: 'Dr. Martin Luther will have it so,'…I will have it so, and I order it to be so, and my will is reason enough. I know very well that the word 'alone' is not in the Latin or the Greek text" (Stoddard J. Rebuilding a Lost Faith. 1922, pp. 101-102; see also Luther M. Amic. Discussion, 1, 127). This passage strongly suggests that Martin Luther viewed his opinions, and not the actual Bible as the primary authority--a concept which this author will name prima Luther."I'll say one thing for him, he was unintentionally funny.
