A convert and pupil of Origen who led the Alexandrian catechetical school and became Bishop of Alexandria, enduring persecution and guiding the Church through crisis.
The Holy Hieromartyr Dionysius the Great, Bishop of Alexandria
Dionysius of Alexandria, surnamed "the Great," was a third-century bishop of Alexandria whom the Church remembers as a teacher, a confessor under persecution, and a guide through several of the doctrinal and disciplinary crises of his age. Born around 190 to a wealthy pagan family of the city, he converted to Christianity as an adult and entered the Catechetical School of Alexandria, where he studied under Origen. He rose to lead that school and, around 248, was raised to the episcopal throne of Alexandria, which he held until his death.
His tenure spanned the imperial persecutions under Decius and Valerian, during which he was hunted, captured, and exiled, yet survived to continue governing his church. Later writers, including Eusebius of Caesarea and Basil the Great, honored him with the title "the Great." The Orthodox calendar commemorates him as a hieromartyr on October 5.
By sharing in the ways of the Apostles,
you became a successor to their throne.
Through the practice of virtue, you found the way to divine contemplation, O inspired one of God;
by teaching the word of truth without error, you defended the Faith,
even to the shedding of your blood.
Hieromartyr Dionysius, entreat Christ God to save our souls.

Dionysius belonged to the intellectual tradition of the Catechetical School of Alexandria, having studied there under Origen and Heraclas before himself directing the school. His later elevation to the episcopate did not, by some accounts, sever him from that teaching office, and he is counted among the school's most influential heads.
Dionysius was drawn into several of the controversies that divided the third-century Church. In the schism associated with Novatian, he declined to support Novatian's claim to the see of Rome, supporting Cornelius instead, and held that lapsed Christians could be readmitted after penitence rather than rebaptized; the sources record his conviction that the Eucharist should be refused to no one who sought it at the point of death.
He opposed chiliasm, the expectation of a literal thousand-year earthly kingdom of Christ. The sources also report that he used the title "Theotokos" for the Virgin Mary around the year 250 and affirmed the divinity of Christ against the teaching of Paul of Samosata.
Eusebius of Caesarea and Basil the Great referred to Dionysius as "the Great," a surname that has remained attached to his name. He is venerated across the historic Christian traditions, and the Orthodox Church commemorates him as a hieromartyr on October 5.
