Dionysius the Great () 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." Early life Dionysius was born to a wealthy polytheistic family sometime in the late 2nd, or early 3rd century. He spent most of his life reading books and carefully studying the traditions of polytheists. He converted to Christianity at a mature age and discussed his conversion experience with Philemon, a presbyter of Pope Sixtus II.

He eventually became leader of the school and presbyter of the church, succeeding Pope Heraclas in 231. Later he became Pope of the church of Alexandria & Patriarch of the See of St. Mark in 248 after the death of Pope Heraclas.

Dionysius’ correspondences included interpretations on the Gospel of Luke, the Gospel of John and the Book of Revelation. During 249, a major persecution was carried out in Alexandria by a polytheist mob, and hundreds were assaulted, stoned, burned or cut down on account of their refusal to deny their faith. Dionysius managed to survive this persecution and the civil war that followed. In January 250 the new emperor Decius issued a decree of legal persecution. Out of fear many Christians denied their faith by offering a token polytheist sacrifice, while others attempted to obtain false documents affirming their sacrifice. Others who refused to sacrifice faced public ridicule and shame among their family and friends, and, if found by
