"Constantine had hoped to be baptized in the Jordan River, but perhaps because of the lack of opportunity to do so—together possibly with the reflection that his office necessarily involved responsibility for actions hardly compatible with the baptized state—he delayed the ceremony until the end of his life. It was while preparing for a campaign against Persia that he fell ill at Helenopolis. When treatment failed, he made to return to Constantinople but was forced to take to his bed near Nicomedia. There, Constantine received baptism, putting off the imperial purple for the white robes of a neophyte; and he died in 337. He was buried at Constantinople in his church of the Apostles, whose memorials, six on each side, flanked his tomb. Yet this was less an expression of religious megalomania than of Constantine’s literal conviction that he was the successor of the evangelists, having devoted his life and office to the spreading of Christianity."
