It appeared that the Theologians of Weimar were particularly opposed to any union or compromise. These held a separate meeting in Weimar, January, 1556, in which they declared that they would not unite with those of Wittenberg, until they would pledge themselves unequivocally to the Augsburg Confession, and would drop all Zwinglianism and Synergism. They would faithfully abide by Luther's doctrine concerning the Lord's Supper and free will.
Amsdorf, Schnepf, Strigel, Stolz, Aurifaber, and delegates from the Palatinate and Wurtemberg, attended this meeting. Melanchthon called this Synod the _Flacian Synod_, because he well knew that Flacius exerted a great influence upon it. He expresses his regrets in regard to this, in a letter to Camerarius, February 7th: "This sad dissension troubles me so much, that I wish to leave this world; and I see that I am not far distant from my journey's end."
But something occurred in the summer of the year 1556, which he perhaps expected least of all. Flacius endeavored to bring about a reconciliation with his former teacher. He was at that time residing in Magdeburg, and had prepared a few "mild propositions to bring about a godly, needful, and peaceful reconciliation between the Theologians of Wittenberg and Leipzig, and others who have written against them," which he had sent to Paul Eber, that he might deliver them to Melanchthon. In the eleventh article he said, "If any persons shall teach and spread errors which are injurious to religion and conscience, either publicly or secretly, we will avoid such as a curse, and will not acknowledge them as brethren, or receive them into fellowship, until they have condemned and publicly renounced their errors. For such wounds in the church cannot be healed or endured silently." It was principally owing to this article that Eber did not present these propositions.
