Not sure that will help Luther’s reputation! For someone who claimed to believe Sola Scriptura, he didn’t seem to mind changing the scriptures to fit his dogma:
The Bible, in Romans 3:28, states,
Therefore we conclude that a man is justified by faith apart from the deeds of the law.
Martin Luther, in his German translation of the Bible, specifically added the word “allein” (English ‘alone’) to Romans 3:28-a word that is not in the original Greek. Notice what Protestant scholars have admitted:
…Martin Luther would once again emphasize…that we are “justified by faith alone”, apart from the works of the Law" (Rom. 3:28), adding the German word allein (“alone”) in his translation of the Greek text. There is certainly a trace of Marcion in Luther’s move (Brown HOJ. Heresies: Heresy and Orthodoxy in the History of the Church. Hendrickson Publishers, Peabody (MA), 1988, pp. 64-65).
Furthermore, Martin Luther himself 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).
Martin Luther has also been charged with intentionally mistranslating Matthew 3:2, Acts 19:18, and many other scriptures (ibid, p. 200).
Matthew 3:2 states,
“Repent, for the kingdom of heaven is at hand!”.
Martin Luther, in his German translation, changed the word ‘repent’ to ‘mend’ or ‘do better’ (ibid, p. 201), presumably to justify his position that one does not need to obey God’s laws through repentance.
Martin Luther, for example, taught,
Be a sinner, and sin boldly, but believe more boldly still. Sin shall not drag us away from Him, even should we commit fornication or murder thousands and thousands of times a day (Luther, M. Letter of August 1, 1521 as quoted in Stoddard, p.93).
He seemed to overlook what the Book of Hebrews taught:
For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries (Hebrews 10:26-27).
The Bible, in Acts 19:18, states,
“And many who had believed came confessing and telling their deeds…”
Yet Martin Luther rendered it, “they acknowledged the miracles of the Apostles” (O’Hare, p. 201).
