Erasmus, however, was not to be moved from his decision; indeed, he felt still further provoked to write by an allusion of Luther’s in the above letter to the kindness he had hitherto displayed towards godless and hypocritical foes; should Erasmus dare to come forward against him publicly Luther vows he will alter this tone.[735] In the latter event Luther, in another passage of the letter, had declared regretfully, in perfect accordance with his theory of grace and the absence of free-will, that “Erasmus had not yet received from the Lord the gift of strength and an inward mind,” which would have enabled him to ally himself freely and trustfully with him (Luther) in his struggle with the monsters who were attacking him; even from Erasmus one could not expect what was beyond his power and lay outside his way. “On the contrary, we have accepted with patience and respect your weakness and the limitation of God’s gift in you.”
We may perhaps be permitted to remark here concerning the absence of the Divine action on the will, that Luther on other occasions did not allow himself to be swayed by “patience and respect,” as in the case of Erasmus, least of all when dealing with the Pope and his supporters. On the contrary, he reproves them severely for their “terrible blindness” and says, that the wrath of God had led to the setting up of an empire of error and lying, in spite of the Church having been so often warned by Christ and the Apostles against the Pope, i.e. Antichrist. The only explanation was in 2 Thessalonians ii. 10: “Therefore God sent upon them the operation of error, to believe lying”; “this operation was so great (‘_illa energia tam potens fuit_’) that they were blind even to the worst errors”; thus it was that they had set up their horrid Papacy. Out upon you, he cries to those, who, on the Lutheran hypothesis, were unable to do otherwise, “the overwhelming effect of your delusion defies all opposition” (“_illa efficacia erroris potentissime restitit_”). “But I have attacked the Pope in his very marrow and teaching, not merely his abuses.” “Had I not brought about his downfall by means of the Word, the devil himself would have vomited him forth.”[736]
The work of Erasmus, “_De libero arbitrio diatribe_,” which appeared in that same year, 1524, at Basle, was a severe blow to Luther.[737]
