Luther was much less down-hearted at that time, having just succeeded in overcoming a persistent attack of anxiety and remorse of conscience. His character, so vastly different from that of his friend, now, after the victory he had won over his “temptations,” was more than ever inclined to violence and defiance. Luther, such at least is his own account, refused to entertain any fear concerning the success of his cause, which was God’s, in spite of the storm threatening at Augsburg. _Melanchthon at the Diet of Augsburg, 1530._ At Augsburg the most difficult task imaginable was assigned to Melanchthon, as the principal theological representative of Lutheranism. His attitude at the Diet was far from frank and logical. He made his own position quite puzzling by his vain endeavour to unite things incapable of being united, and to win, by actual or apparent concessions, temporary toleration for the new religious party within the Christian Church to which the Empire belonged. Owing to his lack of theological perspicuity he does not appear to have seen as clearly as Luther how hopeless was the rupture between old and new. He still had hopes that the Catholics would gradually come over to the Wittenberg standpoint when once an agreement had been reached regarding certain outward and subordinate matters, as he thought them. “Real unification,” as Johannes Janssen says very truly, “was altogether out of the question.” For the point at issue in this tremendous ecclesiastical contest was not this or that religious dogma, this or that addition or alteration in Church discipline; it was not even a question merely of episcopal jurisdiction and the sense in which this was understood and allowed by Protestant theologians; what was fundamentally at stake was no less than the acceptance or rejection of the doctrine of the infallibility of the Church, and the recognition or non-recognition of the Church as a Divine and human institution of grace, resting upon the perpetual sacrifice and priesthood. The Protestants rejected the dogma of the infallibility of the Church and set up for themselves a novel ecclesiastical system, they also rejected the perpetual sacrifice in that they denied the doctrine of the perpetual priesthood.... Hence the attempts at reconciliation made at Augsburg, as indeed all later attempts, were bound to come to nothing.[1083]
