Pope_Dionysius_of_Alexandria--Saint_Bernadette

Dionysius the Great (Ancient Greek: Διονύσιος Ἀλεξανδρείας) was the 14th Pope and Patriarch of Alexandria from 28 December 248 until his death on 22 March 264. Most information known about him comes from his large surviving correspondence. Only one original letter survives to this day; the remaining letters are excerpted in the works of Eusebius.
Called "the Great" by Eusebius, Basil of Caesarea and others, he was characterized by the Catholic Encyclopedia as "undoubtedly, after St. Cyprian, the most eminent bishop of the third century... like St. Cyprian, less a great theologian than a great administrator."
