Magnificat, Mary spoke for the whole church. Standing under the cross, Mary suffered like no other human being. Consequently, Christians have to unite with her under the cross, in order to become Christ-like. Views on natural philosophy In lecturing on the Librorum de judiciis astrologicis of Ptolemy in 1535–1536, Melanchthon expressed to students his interest in Greek mathematics, astronomy and astrology. He considered that a purposeful God had reasons to exhibit comets and eclipses. He was the first to print a paraphrased edition of Ptolemy's Tetrabiblos in Basel, 1554. Natural philosophy, in his view, was directly linked to Providence, a point of view that was influential in curriculum change after the Protestant Reformation in Germany. In the period 1536–1539 he was involved in three academic innovations: the refoundation of Wittenberg along Protestant lines, the reorganization at Tübingen, and the foundation of the University of Leipzig. Death Before these theological dissensions were settled, Melanchthon died. Only a few days before his death, he had written a note which gave his reasons for not fearing death. On the left of the note were the words, "You will be delivered from sins, and be freed from the acrimony and fury of theologians"; on the right, "You will go to the light, see God, look upon his Son, learn those wonderful mysteries which you have not been able to understand in this life." The immediate cause of death was a severe cold which he had contracted on a journey to Leipzig in March 1560, followed by a fever that consumed his strength. His body had already been weakened by many sufferings. He was pronounced dead on 19 April 1560. In Melanchthon's last moments, he continued to worry over the desolate condition of the church. He strengthened himself in almost uninterrupted praying and in listening to passages of Scripture. The words of John 1:11-12 were especially significant to him. "His own received him not; but as many as received him, to them gave he power to become the sons of God." When Caspar Peucer, his son-in-law, asked him if he wanted anything, he replied, "Nothing but heaven." His body was buried beside Luther's in the Schloßkirche in Wittenberg. He is commemorated in the Calendar of Saints of the Lutheran Church–Missouri Synod on 16 February, his birthday, and in the calendar of the Evangelical Lutheran Church in America on 25 June, the date of the presentation
