On the 17th of April he departed, accompanied by JUSTUS JONAS, the son of the Rector, and JEROME SCHREIBER, and reached Bonn, where the Archbishop resided, on the 4th of May. He writes to some one, that two plans of reformation had been proposed; one, which was simple and pure, prepared by Bucer; the other, by Groper, who endeavored to excuse and establish abuses, as we may suppose from the book of Ratisbon. What strange sights met his eyes here! He writes to Camerarius: "You could not look without tears upon the ruin of the churches here, in which crowds of people still daily run to the images of the Saints. This is the main thing of religion, in the eyes of the ignorant multitude." He wrote the same to Bugenhagen, and especially referred to the deplorable ignorance of the clergy. And yet Groper, in his own way, wished to hold fast this state of things. The aged Archbishop, of whom Melanchthon says that he has the best intentions, "confesses that an improvement is necessary, and protests that he wishes a true and thorough reformation, and that he is not afraid of dangers." He therefore placed more confidence in Bucer than in Groper. Although the nobility and the cities expressed themselves favorable to such a reformation, they were opposed by Cologne and the Chapter. The Landgrave informed the Archbishop that he and the other allies would come to his assistance, should it be necessary. Pistorius assisted Bucer. Melanchthon writes to Luther of both these men, that their preaching was largely attended, and that they taught pure and correct doctrine. He superintended their labors, and wrote to Cruciger, May 23d, that the entire work was almost completed, and that he would extricate himself as soon as possible. A short time before this, he also sent a little letter to his son Philip, which we cannot bear to omit here: "Although I have public cares enough, I yet also bear the domestic ones about with me. These you should lighten by your diligence and obedience, especially as you know with how much love we have raised and cared for you. I therefore admonish you, that you walk in the fear of God, and strive, first of all, to please God, the eternal Judge, and then also good men, and that you will show greater diligence and care in this for my sake. Heartily obey your mother, whom you could already support by your age and virtue."
