Controversies With Flacius
The last eventful and sorrowful period of his life began with controversies over the Interims and the Adiaphora (1547). It is true, Melanchthon rejected the Augsburg Interim, which the emperor tried to force upon the defeated Protestants; but in the negotiations concerning the so-called Leipzig Interim he made concessions which many feel can in no way be justified, even if one considers his difficult position, opposed as he was to the elector and the emperor.
In agreeing to various Roman usages, Melanchthon started from the opinion that they are adiaphora if nothing is changed in the pure doctrine and the sacraments which Jesus instituted, but he disregarded the position that concessions made under such circumstances have to be regarded as a denial of Evangelical convictions.
Melanchthon himself perceived his faults in the course of time and repented of them, perhaps having to suffer more than was just in the displeasure of his friends and the hatred of his enemies. From now on until his death he was full of trouble and suffering. After Luther's death he became the "theological leader of the German Reformation," not indisputably, however; for the Lutherans with Matthias Flacius at their head accused him and his followers of heresy and apostasy. Melanchthon bore all accusations and calumnies with admirable patience, dignity, and self-control.
