§ 13. That faith now encountered new enemies, who did not resort to fire and the sword, but who adopted more insidious means for corrupting divine truth; and again, assaults like theirs, only increased the jealousy with which the genuine Lutherans guarded the purity of their doctrinal system. It was the only gift of heaven, which sin and Satan could not touch, and which retained all its unsullied holiness. The soul of man had become corrupt; the body was subject to disease and death; the world, fair as it was, and rich in the gifts of God, had nevertheless been made by sin to bring forth thorns and thistles. But the Gospel truth, which conducted men to Christ and heaven, remained in all its purity and power. These men were willing to suffer and die, but while they did live, they could not relax the grasp with which they held fast to evangelical truth. Now, amid the political and religious commotions of that stormy age, could we expect that devout men should say, “Peace, peace;” when there was no peace? (Jerem. 6:14.) § 14. Let us illustrate this subject. Schwenkfeldt, for instance (born in 1490; died, 1561), an opponent of both the Lutherans and the Reformed, as well as of the Papists, and, accordingly, constantly engaged in controversies with all parties, declared that Luther’s uncompromising determination to maintain the authority of the written word of revelation, the Bible, was equivalent to a worship of the letter. He assigned, in his fanaticism and morbid mysticism, a rank to an inner and direct word of the Divine Spirit, which he asserted that he received, far above that of the written word of God. He refused to make any distinction between the divine act of the justification of the believer, on the one hand, and the progressive sanctification of the believer, on the other. He taught that the two natures of Christ, the divine and the human, were so fused together, or, rather, that the flesh of Christ was so absolutely deified or converted into God himself, that no distinction between them remained,—that the regenerate could live without sin, etc. He succeeded, in spite of the crudeness, one-sidedness, and unsoundness of his doctrines, in attracting many disciples. His death, which occurred in 1561, a few years after Arndt’s birth, did not terminate the widespread confusion which he had created in the Protestant Church; the dread of that sickly form of mysticism which he attempted to establish, long remained. The fear was naturally entertained that it might lead many astray, who, while they did not otherwise fraternize with Schwenkfeldt in his wild and absurd course, might be deluded by his claims to superior religious intelligence and holiness.
