During this confinement, Luther's opinions gained ground in Saxony. The University of Wittenberg made several alterations in the form of Church worship, abolishing, in particular, the celebration of private masses for the souls of the dead. Two events counteracted the pleasure of the reformer when the news came to him. He was told that the ancient University of Paris had condemned his doctrines, and that Henry VIII of England had written a reply to one of his books, so ably that the Pope had been delighted to confer on him the title of Defender of the Faith. In 1522, Luther returned to Wittenberg, enjoying a harmless jest at Jena by the way. There his disguise of red mantle and doublet so deceived fellow-travellers that they told him their intention of going to see Martin Luther return, without realizing that they were speaking to the great reformer! His next sermons were not fortunate in their results, since the peasants failed to understand them. A class war followed, in which Luther took the part of mediator, {60} trying to show his poorer neighbours the evils their violence would bring on themselves, and reproaching the nobles with their oppressive customs. He was angry that the new religious spirit should be discredited by social disorder, and spoke bitterly of all who refused to heed his remonstrances. Erasmus was shocked by Luther's roughness of speech, and withdrew more and more from the reforming party. He hated the old monkish teaching and desired literary freedom, but he could not forgive the excesses of this thorough-going reformer. In 1523, Luther gave grave offence to many of his own followers by marrying Catherine von Bora, a nun who had left her convent. He had cast off the Roman belief that a priest should never marry, but public feeling could not approve of a change which was in conflict with so many centuries of tradition. The Reformer's home life was happy, nevertheless, and six children were born of the marriage. As a father, Luther showed much tenderness. He wrote with a marvellous simplicity to his eldest son: "I know a very pretty, pleasant garden and in it there are a great many children, all dressed in little golden coats, picking up nice apples and pears and cherries and plums, under the trees. And they sing and jump about and are very merry; and besides, they have got beautiful little horses with golden bridles and silver saddles. Then I asked the man to whom the garden belonged, whose children they were, and he said, 'These are children who love to pray and learn their lessons, and do as they are bid'; then I said, 'Dear sir, I have a little son called Johnny Luther; may he come into this garden too?'"
