[Turning from the study of law to the study of theology under Luther's influence, Jerome Weller (1499-1572) spent eight years, from 1527 to 1535, in almost daily contact with Luther, in whose home he lived and whose children he tutored.Later he was a teacher of theology in his native Freiberg, Saxony.His shyness and modesty made him particularly subject to fits of depression, and the following letter was addressed to him at such a time by Luther, who was absent from his home.]
Grace and peace in Christ.
My dear Jerome:
You must believe that this temptation of yours is of the devil, who vexes you so because you believe in Christ. You see how contented and happy he permits the worst enemies of the gospel to be. Just think of Eck, Zwingli, and others. It is necessary for all of us who are Christians to have the devil as an adversary and enemy; as Saint Peter says, "Your adversary, the devil, walketh about."
Excellent Jerome, you ought to rejoice in this temptation of the devil because it is a certain sign that God is propitious and merciful to you. You say that the temptation is heavier than you can bear, and that you fear that it will so break and beat you down as to drive you to despair and blasphemy. I know this wile of the devil. If he cannot break a person with his first attack, he tries by persevering to wear him out and weaken him until the person falls and confesses himself beaten. Whenever this temptation comes to you, avoid entering upon a disputation with the devil and do not allow yourself to dwell on those deadly thoughts, for to do so is nothing short of yielding to the devil and letting him have his way. Try as hard as you can to despise those thoughts which are induced by the devil. In this sort of temptation and struggle, contempt is the best and easiest method of winning over the devil. Laugh your adversary to scorn and ask who it is with whom you are talking. By all means flee solitude, for the devil watches and lies in wait for you most of all when you are alone. This devil is conquered by mocking and despising him, not by resisting and arguing with him. Therefore, Jerome, joke and play games with my wife and others. In this way you will drive out your diabolical thoughts and take courage.
This temptation is more necessary to you than food and drink. Let me remind you what happened to me when I was about your age. When I first entered the monastery it came to pass that I was sad and downcast, nor could I lay aside my melancholy. On this account I made confession to and took counsel with Dr. Staupitz (a man I gladly remember) and opened to him what horrible and terrible thoughts I had. Then said he: "Don't you know, Martin, that this temptation is useful and necessary to you? God does not exercise you thus without reason. You will see that he intends to use you as his servant to accomplish great things." And so it turned out. I was made a great doctor (for I may with propriety say this of myself) although at the time when I suffered this temptation I never would have believed it possible. I have no doubt that this will happen to you too. You will become a great man. Just see to it that you are of good courage in the meantime, and be persuaded that such utterances, especially those which fall from the lips of learned and great men, are not without prophetic quality.
I remember that a certain man whom I once comforted on the loss of his son said to me, "Wait and see, Martin, you will become a great man."I have often thought of these words, for, as I have said, such utterances have something of a prophetic quality. Be of good courage, therefore, and cast these dreadful thoughts out of your mind. Whenever the devil pesters you with these thoughts, at once seek out the company of men, drink more, joke and jest, or engage in some other form of merriment. Sometimes it is necessary to drink a little more, play, jest, or even commit some sin in defiance and contempt of the devil in order not to give him an opportunity to make us scrupulous about trifles. We shall be overcome if we worry too much about falling into some sin.
