Did Martin Luther Write Sin Boldly?

As a reference librarian, I frequently get asked whether (and where!) Martin Luther said a quotation people claim he said. Most of the time when I am asked to do so, I cannot find a place where he is recorded as saying or writing such a thing. That is not the case with the Luther quote “sin boldly,” which is often used by his opponents to claim Luther rejects God’s law for Christians. The short answer is: yes, he wrote this phrase, but, no, it does not mean what his opponents think it means.

Five hundred years ago today, Luther was living in the Wartburg Castle — kind of as a safe house of sorts — under the name of Junker Jorg. At first he had a difficult time adjusting — his diet switched from that of a monk to that fit for a noble. By August he was settling in. He was far from idle there. Among the things he did was write an incredible number of letters to friends, allies, his prince and others. Few people knew exactly where he was — the letters all went to his friend Georg Spalatin, who was the chancellor for his prince Frederick the Wise. Spalatin then sent them on.

Soon Luther’s friends used the same channel to reply and to ask advice as to how to proceed in his absence. The letter where Luther writes — in Latin — “sin boldly” was penned August 1st, 1521. In it Luther addresses the questions of whether monks should be held to their monastic vows and whether priests should be allowed to marry. Luther criticized these — among other things — as man-made laws. That these were to be valued more highly than God’s Word was a false commandment. To violate them was not a sin but an imaginary sin.

Serious Christians, such as Luther himself, had tortured themselves trying to observe such traditions. They felt great burdens of guilt for breaking these. Apparently Melanchthon and Luther’s allies couldn’t decide whether or not to set these aside. Luther’s advice was not to worry about these so called sins. Be bold to just live their lives, but believe in Christ who forgives sins even more boldly.

In this sinful world, Christians will never be free of sin. As another so-called Luther quote (this one he didn’t likely say) goes: “the Old Adam is a good swimmer.” He is drowning in Baptism, but doesn’t give up without a good fight! As Christians we need to remember to look to Jesus. He bore all our real sins to the cross. There he paid the full price due for our sin and the sins it performs and removes them forever. In Christ we die to rise again on the last day without sin.

So, Luther’s Advice to Melanchthon is good here is how he put it: “If you are a preacher of mercy, do not preach an imaginary but the true mercy. If the mercy is true, you must therefore bear the true, not an imaginary sin. God does not save those who are only imaginary sinners. Be a sinner, and let your sins be strong, but let your trust in Christ be stronger, and rejoice in Christ who is the victor over sin, death, and the world. We will commit sins while we are here, for this life is not a place where justice resides. We, however, says Peter (2. Peter 3:13) are looking forward to a new heaven and a new earth where justice will reign. It suffices that through God’s glory we have recognized the Lamb who takes away the sin of the world. No sin can separate us from Him, even if we were to kill or commit adultery thousands of times each day. Do you think such an exalted Lamb paid merely a small price with a meager sacrifice for our sins? Pray hard for you are quite a sinner.”
