The idea that the ecclesiastical reconciliation of Christendom was still possible--apart from the banned and recalcitrant sovereign of England--was one of which a considerable body of Churchmen by no means despaired. There were men like Contarini and Pole on the one side and Melanchthon on the other whose doctrinal attitude did not seem to be hopelessly irreconcilable. But while the Lutherans demanded for themselves a latitude of opinion beyond what the Pope would ever have been prepared to concede, the two sides laid down two contradictory propositions as the condition of reconciliation, in respect of the validity of Papal authority. Each was willing, even anxious, for a General Council; but neither would admit one unless so constituted as to imply that its own view was postulated and _ipso facto_ the opposing view ruled out of court. The Emperor, though anti-Lutheran, was unwilling either to enforce his view at the sword's point, or to subordinate himself to the Pope. The French King was equally ready to win papal favour by persecuting his own protestant subjects, and to encourage the protestant subjects of the Emperor, according as one course or the other seemed more likely to embarrass Charles. Finally the Pope, while set upon the suppression of the Lutheran heretics, was desperately afraid of the accession of strength to Charles which would result from their complete disappearance as a political factor: and he was almost equally afraid that if a Council could not be carried through, Charles would call a national Synod of the Empire to settle the religious question independently.

Thus attempts to bring about a General Council failed repeatedly. The nearest approach to reconciliation was achieved when a conference was arranged at Ratisbon (1541) at which there were papal as well as Lutheran representatives and it seemed as if common ground of agreement was in course of emerging. But Luther himself held aloof; Paul III. would not ratify the concessions that Contarini and others were willing to make. The Conference ended in failure; and Charles--always embarrassed in his dealings with the Protestants by his need of their support against threatening Turkish aggression--was obliged, a good deal against his private inclinations, to reaffirm the Nuremberg toleration. The result was a renewal of negotiations between Pope and Emperor for the calling of a General Council; whereof the outcome was that in May 1542 the Pope summoned the famous Council of Trent which did not conclude its sittings till twenty years later. Although the Council was formally called for the end of the year, it did not succeed in holding a working Session till 1546; after the spring of 1547 it was transferred to Bologna; nor did it get to work again (once more at Trent) till 1551. The fundamental point however is that, by its constitution, the Lutheran controversy was prejudged and the Lutheran party effectively excluded. It was not a Council representing Christendom; it stood for the Church of Rome seeking internal reformation for itself and arrogating Catholicity to itself. Hence arose the custom of using the terms Catholic and Protestant as party labels for those within and without the "orthodox" pale, in spite of the objection more particularly of the Anglican body to its implied exclusion from the "Catholic" Church and inclusion in the same category with the Lutheran and Calvinistic bodies. The historian cannot admit that Rome has a right to monopolise the title of Catholic; but during the period when Europe was practically divided politically into two religious camps, it is difficult to avoid using the current labels though their adoption is in some degree misleading.
