Luther said, and said truly, of his Protestant doctrinal opponents, "these men are of another spirit," and at the Conference of Marburg, in 1529, when the whole future of Protestantism seemed to hang upon the union of the Swiss with the German branch, his personal insistence upon the out-and-out literalness of the Catholic symbol prevented that union forever. He saved the Lutheran Church from the reproach of fanaticism and left the Swiss Church free to follow its more liberal course. That is where the Eucharist question drew near Erasmus. He began to feel the approach of danger and, characteristically, to prepare for it. We have no special treatise on the subject from his hand, though he is said to have written and suppressed two such. His expressions in regard to it are scattered through his apologetic writings. In the "Apology against Certain Spanish Monks," published in 1528, there is a chapter[161] in which he replies to criticism on this point. Here, as everywhere, he tries to draw a clear line between what is essential and what is non-essential to the Christian faith. Hutten, he says, found fault with him because he was not willing to expose himself to all perils for the sake of Luther's doctrine, but he had replied:
"I would gladly be a martyr for Christ, if he would give me strength, but I am not willing to be a martyr for Luther.... Now if it were an important article of faith that the Mass is not a sacrifice, as Luther maintains, death ought to be sought and inflicted on its account.... What I call articles of faith are those handed down in all the creeds which the Church repeats,—and yet I do not deny the use of this phrase for some doctrines that are not expressed in the creeds. As to the reasons why the Eucharist is called a sacrifice, there is still a difference among theologians as there is also on many points about the primacy of the pope.... When I have stated that we ought to agree with the Church in all points, even if man's reason and the apparent meaning of Scripture were opposed, I make it clear enough that I will conform at once, if anyone will prove to me what the Church teaches on this point."
As regards the communion in both kinds, his critics tried to trip him on the ground of a letter to Bohemia in which he had seemed to show some favour to the new-old doctrine. He protests that he never meant to question the teaching of the Church but only to suggest that more weighty reasons than he had as yet heard ought to be given for changing a practice which undoubtedly prevailed in the early centuries of the Church.
"Nor do I doubt that there were such reasons, which perhaps on account of some scruple they preferred not to mention;—for it is not an impious thing in itself to partake under both forms.... As for the charge that on this point as on many others I agree with Luther, if I should say that is a straight lie, they would think me lacking in courtesy; but bad luck to that crafty book from which these extracts are taken! I try to persuade men to conform to the requirements of the Roman Church in partaking of the Eucharist; is that agreeing with Luther? Let anyone read what he writes on this business!"
So anxious was Erasmus to set himself right with the world on this all-important topic, that in 1530, after his removal to Freiburg, he published an edition of a treatise by one Algerus, a Benedictine monk of Liege, who died at Cluny in 1131. This work, entitled A Treatise on the Sacrament of the Body and Blood of our Lord, was written in refutation of Berengar of Tours. In his dedication[162] Erasmus says: "I have never doubted the reality of the body of the Lord, and yet somehow by the reading of this work my faith has been not a little confirmed, and my reverence increased." In the course of this dedication he shows us very plainly the working of his mind. The doctrine he admits to be of original validity, but as to its form, and as to the precise expressions one ought to use, there has been an historical development and this has come about by human means, through the natural process of controversy.
"Would that they who have followed Berengar in his errors would follow him also in his repentance, and that their error may turn to the advantage of the Church! There are innumerable questions about this sacrament, as, how the change of substance takes place; how accidents can exist without a substance; how the bread and the wine retain the colour, the smell, the taste, the power of satisfying, of intoxicating, and of nourishing which they had before they were consecrated; at what moment they begin and cease to be the body and blood of Christ; whether, if the form be destroyed another substance succeeds; how the same body may be in innumerable places; how the very body of a man can be under the least crumb of bread and many other things which may properly be discussed by those of trained intelligence. For the multitude it is enough to believe that after the consecration the bread and the wine are the true body and blood of the Lord, which cannot be divided, nor injured, nor is exposed to any harm, whatever may happen to the elements.... In short, in answer to all the doubts of human reasoning, there comes to us the unlimited power of God, to whom nothing is impossible and nothing difficult."
In other words, Erasmus in 1530 is perfectly satisfied with the same mental attitude which Paschasius had displayed in the ninth century, at a moment when European culture was but just rising above its lowest point. His only criticism is reserved for the excesses of the Church system. His description of the proper state of mind of the devout worshipper is spiritual enough to be adopted by the most eager Protestant.
"Once," he says, "when the Church was in its best estate, it knew but one sacrament and the bishop alone performed it. The throng of sacramental persons were attracted first by piety and then by gain. At length the thing has gone so far that many study for the priesthood precisely as one man learns to be a mechanic, another a cobbler, another a mason or a tailor. To these the Mass is only a means of livelihood."
Whenever we find Erasmus protesting with especial vehemence that he does not believe a thing, we may be tolerably sure that he has already given good reason for suspicion that he did believe it. In the case of the Eucharist such suspicion was well grounded. The objections to the doctrine, even on its philosophical side, were such as must have appealed strongly to his common sense. The abuses of it in practice, especially the whole theory of the Mass as a sacrifice, performed by the priest at so much per performance, were precisely of the kind against which he had declaimed all his life long. When the doctrine began to be criticised by the reformers, especially by his Swiss neighbours, he allowed himself some tolerably free expressions of opinion. The leader of Swiss thought on this, as on most theological subjects, was Œcolampadius, the reformed preacher of Basel. He had published his view, and Erasmus' friend, Bilibald Pirkheimer of Nuremberg, had replied, defending a view resembling that of Luther. In June, 1526, Erasmus wrote to Pirkheimer reviewing very briefly the state of the reforming ideas in the several European countries. He says[163]:
"I should not be displeased with the view of Œcolampadius, if the consent of the Church were not against it. For I see no meaning in a body without sensible form, nor what use it could be if it were perceived by the senses, provided only that a spiritual grace were present in the elements. And yet I cannot depart from the consent of the Church and never have so departed. You differ from Œcolampadius in such a way that you seem to prefer to agree with Luther rather than with the Church. You quote Luther with a little more respect than was necessary, when you might have cited the authority of others.... With your usual prudence you will not show this letter to anyone."
