Person
Dionysius of Alexandria
bishop about 248–264
Bishop of Alexandria
Attested. Known mainly from Eusebius and later quotations of his letters.
A pupil of Origen, Dionysius guided Alexandria through plague and persecution. He argued in a technical way against Sabellius that the Father and the Son are not the same person, and then had to reassure Dionysius of Rome that he was not dividing their substance. The exchange previews fourth-century vocabulary.
