Melancthon sat near Luther, and attracted almost equal attention. He was of short stature, and would scarcely have been thought more than eighteen. Luther, who was a whole head taller, seemed to be united to him by the closest friendship; they came in, went out, and walked together. "To look at Melancthon," says a Swiss theologian,[87] who studied at Wittemberg, "one would think him a mere boy, but in judgment, learning, and talent he is a giant. It is difficult to comprehend how so much wisdom and genius can be contained within so puny a body." Between the sittings, Melancthon conferred with Carlstadt and Luther. He assisted them in preparing for the debate, and suggested arguments drawn from the stores of his vast erudition; but during the discussion he remained quietly seated among the spectators, giving close attention to every thing that was said by the theologians.[88] Occasionally, however, he came to the aid of Carlstadt.[89] When the latter was on the point of giving way under the powerful declamation of the chancellor of Ingolstadt, the young professor whispered a word in his ear, or slipt a paper to him on which he had noted down the answer. Eck on one occasion perceived this, and indignant that this grammarian, as he called him, should presume to intermeddle with the discussion, turned towards him, and haughtily said, "Be silent, Philip, keep to your own studies, and give me no disturbance." Perhaps Eck had already a presentiment of the formidable adversary he was afterwards to encounter in this young man. Luther was offended at the rude insult given to his friend; "The judgment of Philip," said he, "weighs more with me than that of a thousand doctor Ecks."

[89] Tace tu, Philippe, ac tua studia cura, ne me perturba. (Ibid., i, 149.) The calm Melancthon easily discerned the weak points of this discussion. "We can only be surprised," says he with the wisdom and grace conspicuous in all his words, "when we think of the violence which was brought to the discussion of such subjects. How could any advantage be derived from it? The Spirit of God loves retreat and silence: there dwell those whose hearts he penetrates. The bride of Christ does not stand in streets and public places, but conducts the Bridegroom into her mother's house."[90] [90] Melancth. Op., p. 134. [Sidenote: LUTHER'S SERMON.
