Nowhere did Luther's character shine forth more strikingly than in this controversy on the Lord's Supper. Never were more clearly displayed that firmness with which he clung to a conviction which he believed to be christian, his faithfulness in seeking for no other foundation than Scripture, the sagacity of his defence, his animated eloquence, and often overwhelming powers of argumentation. But never also were more clearly shown the obstinacy with which he adhered to his own opinions, the little attention he paid to the reasons of his opponents, and the uncharitable haste with which he ascribed their errors to the wickedness of their hearts, or to the wiles of the devil. "One or other of us," said he to the Strasburg mediator, "must be ministers of Satan--the Swiss or ourselves." This was what Capito styled "the frenzies of the Saxon Orestes;" and these frenzies were followed by exhaustion. Luther's health was affected by them; one day he fainted in the arms of his wife and friends; he was a whole week as if in "death and hell."[625]--"He had lost Jesus Christ," he said, "and was tossed to and fro by the tempests of despair. The world was passing away, and announcing by prodigies that the last day was at hand." [625] In morte et in inferno jactatus. L. Epp. iii. 132. But the divisions among the friends of the Reformation were destined to have still more fatal consequences. The Romish theologians exulted, particularly in Switzerland, at being able to oppose Luther to Zwingle. And yet if, after three centuries, the recollection of these divisions should convey to evangelical Christians the precious fruits of unity in diversity, and of charity in liberty, they will not have been in vain. Even then, the reformers, by opposing one another, showed that they were not governed by a blind hatred against Rome, and that truth was the primary object of their inquiries. Herein we must acknowledge there is something generous; and conduct so disinterested did not fail to bear fruit, and to extort, even from enemies, a feeling of interest and esteem. [Sidenote: DIFFERENT TENDENCIES.] And further than this, we may here again recognise that sovereign hand which directs all things, and permits nothing without the wisest design. Luther, notwithstanding his opposition to the Papacy, was in an eminent degree conservative. Zwingle, on the contrary, was inclined to a radical reform. These two opposite tendencies were necessary. If Luther and his friends had stood alone at the time of the Reformation, the work would have been stopped too soon, and the reforming principle would not have accomplished its prescribed task. If, on the contrary, there had been only Zwingle, the thread would have been snapped too abruptly, and the Reformation would have been isolated from the ages that had gone before.
