Luther was convinced he was right. He absolutely no interest in reconciling with the pope That would have entailed his accepting Erasmus’ views which, as you know Luther refused to do. The radical Catholic Reformers also despised Erasmus. Somewhat like Constantine in the 4th Century. the Emperor wanted a political solution to a theological issue, But neither the Reformers nor the Archcatholics wanted this. As to my charge againbst Melanthon , read the Protestation of Worms. It is not an honest formulation of the true Lutheran position. In Melanthon’s case, he came very close to Calvinism is his later writings when he was no longer dominated by Luther’s overwhelming personality.
More and more so as time went by.

"He had absolutely no interest in reconciling with the pope"... due to a large extent to his lack of trust in the integrity of the pope.
