For the moment the discussion turned on the question of indulgences. On this subject Erasmus had made no utterance which could be understood as committing him on the theory as a whole. In the Praise of Folly he had ridiculed the grosser absurdities of the practice, especially the counting up of the days and years of redemption from Purgatory, as if salvation were a thing of the multiplication-table. The teaching of the Enchiridion was hopelessly against any such conception of moral regeneration. Anyone who had read Erasmus could not have a moment's doubt that the system of indulgences, as it was practised throughout Europe, must have been repulsive to him in the extreme. The idea that Erasmus could ever have invested a penny in such traffic for the advantage of his own soul or that of anyone dear to him, was grotesquely absurd. Moreover the circumstances of that special sale of indulgences in Germany which called out the wrath of Luther were such as must have seemed equally outrageous to Erasmus. The barefaced openness with which the Prince Elector of Mainz had lent himself to the papal exaction, on condition that half the plunder should go into his own pocket to pay for the pallium which the papacy itself had just granted him, brought out into clearest relief the purely mercantile nature of the whole transaction. It required all the hair-splitting of all the schools to carry a man through the stages of that bargain and leave him at last with any tenderness whatever for the system that made it possible. Yet this was precisely the feat which Erasmus was apparently to perform.
We gain a glimpse at the working of his mind on this subject in the letter to Volzius, called forth by criticism of the Enchiridion, and dated in August, 1518[121]:
"If anyone finds fault with the preposterous opinion of the vulgar, which gives to the highest virtues the lowest place and vice versa and is specially shocked by unimportant evils and the reverse, then one is straightway called to account as if one favoured those evils which seem to him less than some other evil; or as if he were condemning certain good actions because he thinks others are even better. So if one teaches that it is safer to trust in good deeds than in the papal pardons, he is not condemning those pardons, but is giving the preference to what is more certainly in accord with the teaching of Christ. So also, if one thinks that they act more wisely who stay at home and look after their wives and children, than they who go running about to Rome or Jerusalem or Compostella, and that the money wasted in long and dangerous journeys were much more piously spent upon the worthy and honest poor, one is not condemning the pious impulse of those persons, but is only preferring what comes nearer to true piety. In truth it is not a fault of our times alone to attack certain evils as if they were the only ones, while we smooth over, as if they were not evils at all, others far worse than those we are abusing."
One feels here an allusion to that overemphasis on outward organisation which was to be Erasmus' great objection to the German reform. Instead of this he would have the true value of the institution so clearly brought out that it would counteract all tendency to abuse. This letter was one of the last pieces of Erasmus' writing at Basel before the long illness of which he speaks in the letter about his journey to Louvain. He had spent the year 1518 chiefly at Basel in tireless industry. He arrived at Louvain only, as we have seen, to break down again. It was 1519 before we find him drawn directly into the Lutheran controversy.
The letter to Volzius just quoted was printed as a preface to a new edition of the Enchiridion in 1518. The first step in the correspondence with Luther was taken by Luther himself in March, 1519, and seems to have been suggested by the very passage we have here made use of to show Erasmus' feeling about indulgences. Luther's tone in this first letter is eminently characteristic of his attitude during these early years of his public activity. It is modest and self-depreciating to a degree. Words fail him to express his admiration for the great scholar. It is really monstrous that they should not know each other, when he has so long been worshipping in silence.[122]
"Who is there whose inmost being is not filled by Erasmus? Who is not being taught by Erasmus? In whom does not Erasmus reign?—I mean, of course, among those who have a true love of letters. For I am glad enough and I reckon it among the gifts of Christ, that there are many who do not approve of you. By this test I discern the gifts of a loving from those of an angry God, and I congratulate you that while you are most acceptable to all good men, you are equally disliked by those who would like to be thought the only great ones and the only ones to be accepted. But here am I, clumsy fellow, approaching you thus familiarly with unwashed hands and without formal phrases of reverence and honour, as one unknown person might address another. I beg you by your kind nature, lay this to the account of my affection or my inexperience. In truth, I whose life has been passed among the schoolmen, have not so much as learned how to address a truly learned man by letter. Otherwise, how I would have wearied you already with epistles! I would not have suffered you alone to speak to me all this time in my study. Now, since I have learned from Fabricius Capito that my name is known to you through my trifles about indulgences and learned also from your most recent preface to the Enchiridion, that my notions have not only been seen, but have also been accepted by you, I am compelled to acknowledge, even though in barbarous style, your noble spirit, which enriches me and all men.... And so, my dear and amiable Erasmus, if you shall see fit, recognise this your younger brother in Christ, indeed a most devoted admirer of yours, but worthy, in his ignorance, only to be buried in his corner and to be unknown to the same sky and sun with you."
The letter closes with an affectionate eulogy of Philip Melanchthon as the indispensable companion of his studies.
There is no reason to doubt the sincerity of Luther's attitude at this critical moment. It was quite true that Erasmus was far beyond him in scholarly attainment and reputation. It was true also that the plain meaning of Erasmus' reference to indulgences in the preface to the Enchiridion was directly in accord with Luther's own position in the Theses. If he could be made now, in some more decided manner, to commit himself to Luther's cause, it would be a great point gained for reform.
