Saint Eulogius, Patriarch of Alexandria, was one of the enlightened hierarchs of the sixth century. At first he was igumen of the monastery of the Mother of God in Antioch, and then in 579 he was chosen as Patriarch of Alexandria, where he served for twenty-seven years. Throughout his life, the saint struggled vigorously against heresies. He was also a friend of St Gregory Dialogus (March 12), and some of their correspondence has been preserved.
St Eulogius died in 607 or 608. St Photius quotes from his writings, which reveal an Orthodox theology of the two natures of our Lord Jesus Christ. Only one of his sermons, for Palm Sunday, has survived in complete form.
