Therefore pray God, as we also do, that this union, which, thanks to God, is prospering better and better, may at last be fully established. May God not be merciful to me, if anything is wanting on my part, or if I lay difficulties in the way; so anxious am I that peace should be restored to the Church before my death." Melanchthon had written to the ministers in Augsburg: "I would willingly endanger my life to promote this Concord, and I trust that the way is already prepared for it. May Christ rule and guide the designs of the godly." Thus the two leaders were warmly in favor of the Form of Concord. The place was also appointed, the Elector selecting EISENACH. But all at once, Melanchthon began to fear that greater divisions might be brought about by this conference, as he writes to the Landgrave of Hesse in April: "Now I have all the time feared, if this should be held at this time, that some rigorous individuals might attend, and thus more disunion and offence than improvement would be the consequence." He then goes on to say that no negotiations should be undertaken without the presence of the Landgrave and the other princes and States, and that, on the whole, too great haste should be avoided. His concern may have been caused by an epistle sent forth at this time by Zwingli and Oecolampadius, which could not promote unity. This was prefaced too by a letter of Bucer, who praised these men on account of their orthodoxy. On this account Melanchthon was so anxious, and feared that it would only increase discord. "This disease," he wrote to Veit Dietrich on the 15th of May, "cannot be healed suddenly. But I beseech God in mercy to look upon the Church, and to deliver it from all offences." Notwithstanding all this, the Conference was held. But because Luther suffered great bodily pain at this time, and could not go to Eisenach, he proposed Grimma, which was nearer. Melanchthon was already on the way thither, when Bucer, with his friends Capito and Wohlfahrt, called Lycosthenes, arrived in Wittenberg, May 21, 1536.
