During this season of troubles, he made a brief visit to Bretten, to see his mother. He saw her for the last time, for she completed her earthly pilgrimage on the 6th of June, 1529.[14] CHAPTER X. THE CONFERENCE AT MARBURG. While the Catholics were filled with the most violent enmity against the evangelical party, and dark clouds were gathering over the heads of the Protestants, because of the decided expression of the emperor's will, it was a matter for the very deepest regret that a deep gulf was opened in the midst of the evangelical party, which grew wider and wider in the course of time. This was the rupture between the Lutherans and the Reformed, to use the names familiar now. We have already become acquainted with the restless, stormy spirit of Dr. Carlstadt, whom Melanchthon called the wicked A B C, on account of the initials of the three names, Andrew Bodenstein Carlstadt. Among other errors, he also denied the bodily presence of Christ in the sacrament, and explained the words of institution in so forced a manner, that Luther was doubtful whether he should consider him in earnest, or think that God had hardened and blinded him. Luther simply adhered to the words of Christ, however much, as he confesses himself, he was spurred by his reason to deviate from the words. "But I am a prisoner," he says, "and cannot escape; the text is too powerful, and will not permit its meaning to be changed by words." Melanchthon also strictly held, that the body and blood of Christ are truly and essentially present in the Lord's Supper. Because Carlstadt would not return to Wittenberg, he was obliged to leave the country. But soon after he solicited Luther's intercession, who willingly complied. He returned to Saxony in the year 1525. Luther baptized his son, and his wife and Melanchthon acted as sponsors. But in the year 1527, Luther already expressed himself unfavorably of the man, who still adhered to his ridiculous explanation of the words of the Lord's Supper. Carlstadt now left Saxony, and in 1528 came to Basle, where he was appointed preacher and professor. He soon disappeared in the back-ground, when another, ULRICH ZWINGLI, the Swiss reformer, appeared with his unsatisfactory exposition of the words of the supper, according to which the words "This _is_ my body," were said to mean "This _signifies_ my body." Although he labored with great success in Switzerland, he yet bore some resemblance to Dr. Carlstadt, in his stormy proceedings, for he destroyed the images, bells, organs, and the like. Zwingli took Carlstadt's side against Luther. John Oecolampadius, professor and pastor in Basle, and a friend of Melanchthon's youth, united with him in the same unsatisfactory view of the Lord's Supper.
