Melanchthon not only admitted that an ecclesiastical system with bishops in many cities was lawful, but that the Roman pontiff might preside over the entire episcopate. He countenanced, to a certain extent, the current doctrine respecting human tradition and the retention of auricular confession. He discerned a gradual approach to concord in respect to justification, and found no difficulty in the divergent views of free will and original sin. He did, indeed, insist upon the rejection of the worship of saints, and advocate expunging from the ritual all appeals for their assistance. So, too, monks ought to be allowed to forsake the cloister, and monastic establishments could then be advantageously turned into schools of learning. The celibacy of the clergy should, in like manner, be forthwith granted. There was, however, in his view, one point that bristled with difficulties. How to remove them Melanchthon confessed himself unable to suggest. The question of the popish mass was the Gordian knot which must be reserved for the future council of the church to untie or cut.[329] [Sidenote: His own misgivings.] A faint suspicion seems, however, to have flitted through the Wittemberg reformer's mind, that possibly, after all his large admissions, his attempt was but labor lost! For, in a letter to Martin Bucer, written on the very day he despatched his communication to Du Bellay, he more than hinted his own despair of effecting an agreement with the Pope of Rome, and excused himself for his apparently lavish proffers, on the plea that he was desirous of making his good French friends comprehend the chief points of controversy![330] [Sidenote: A favorable impression made on Francis.] Melanchthon's articles, faithfully transmitted by Du Bellay, produced on the mind of Francis a favorable impression. The ambitious monarch welcomed the prospect of a speedy removal of the doctrinal differences that had previously marred the perfect understanding he wished to maintain with the Protestant princes of Germany. Whether, however, any higher motives than considerations of a political character weighed with him, may well be doubted. Meantime, an unexpected occurrence for the time dispelled all thought of that harvest of conciliation and harmony which the more moderate reformers looked for as likely to spring up from the seed so liberally sown by Melanchthon.
