"Son John" could scarcely be called a brilliant scholar. Indeed, he was a bit dull, and inclined to take things easy. In this his mother seems to have been just a trifle partial to her first-born, and inclined to help him thus take things easy. So, when he was sixteen, "son John" was sent away to school.
From the letter which he bore from his father to Mark Crodel, the teacher of the Latin school in the Saxon town of Torgau, young John seems to have entered the school as a sort of "pupil-teacher," for thus the letter runs:
"According to our arrangement, my dear Mark, I send thee my son John, that thou mayst employ him in teaching the children grammar and music, and at the same time superintend and improve his moral conduct. If thou succeedest in improving him, I will send thee two other sons of mine. For, though I desire my children to be good divines, yet I would have them sound grammarians and accomplished musicians."
Young John would seem to have been sent to Torgau as one needing correction; and, indeed, I am afraid he was not always a good or a dutiful son; otherwise it is hard to explain the words of Luther when one of his friends spoke of the boy's frequent attacks of illness. "Ay," said Dr. Luther, "'tis the punishment due to his disobedience. He almost killed me once, and ever since I have but little strength of body. Thanks to him I now thoroughly understand that passage where St. Paul speaks of children who kill their parents not by the sword, but by disobedience."
Just how the son "nearly killed" his father we cannot say. It may have been the great man's strong way of putting things, but evidently "son John" also needed reformation.
JOHN WAS THE COMPANION OF HIS FATHER IN MANY EXPEDITIONS.
However that may be, we catch more glimpses of John's good side than of his bad. He was the companion of his father in many of his expeditions about Germany, and he was with him on that fatal trip to Eisleben in January, 1546, to reconcile the quarrelsome Counts of Mansfeld.
With his boy he forded the icy rivers Mulde and Saale, where they nearly lost their lives, and where the Reformer doubtless "caught his death." Escorted by horsemen and spearmen, Luther and his son entered Eisleben; the Counts of Mansfeld were reconciled, but Luther fell sick, and that very night, the 18th of February, he died.
All Germany mourned the great man's death; all Germany hoped that his sons might follow in the father's steps. But the three boys seem only to have turned out respectable men, without any of the elements of greatness or leadership.
