Alongside of his readiness in controversy which some admired, many remarked in him quarrelsomeness and disputatiousness. He never learnt how to live “at peace” with his brothers,[53] as some of the old monks afterwards told the Humanist Cochlæus. His Catholic pupil Johann Oldecop, says of his leaving Erfurt for Wittenberg, that the separation was not altogether displeasing to the Augustinians of Erfurt, because Luther was always desirous of coming off victor in differences of opinion, and liked to stir up strife.[54] Hieronymus Dungersheim, a subsequent Catholic opponent who watched him very narrowly, writes that he “had always been a quarrelsome man in his ways and habits,” and that he had acquired that reputation even before ever he came to the monastery.[55] Dungersheim questioned those who had known him as a secular student at Erfurt. The above statements come, it is true, from the camp of his adversaries, but they are not only uncontradicted by any further testimony, but entirely agree with other data regarding his character. Luther, in his own account of himself which he gave later, tells us that he was then and during the first part of his career as a monk, so full of zeal for the truth handed down by the Church that he would have given over to death any denier of the same, and have been ready to carry the wood for burning him at the stake. He also says in his queer, exaggerated fashion, that in those days he worshipped the Pope. At the same time he announces that his study of the Bible at Erfurt had already shown him many errors in the Papist Church, but that he had sought to soothe his conscience with the question: “Art thou the only wise man?” though by so doing he had retarded his understanding of the Holy Scriptures.[56] He also asserts later that his father’s words spoken at the banquet which followed his first Mass, viz. that his religious vocation was probably a delusion, had pierced ever deeper into his mind and appeared to him more and more true. Yet he likewise tells us elsewhere of his persevering zeal in his profession, and of his excessive fastings and disciplines. It is hard to find the real clue in this tangle of later statements, all of them influenced by polemical considerations.
