Constantine as a ‘Bishop’
The author of the Vita Constantini (traditionally and persistently identified with Eusebius, despite the silence of St. Jerome), tells us that Constantine ‘at a banquet he was giving to the bishops declared that he too was a bishop. He added these words which I heard with my own ears: ἀλλ᾽ ὑμεῖϛ μὲν τῶν εἴσω τῆϛ ἐκτὸϛ ὑπὸ θεοῦ καθεσταμένοϛ ἐπίσκοπϛ ἂν εἴην ’.In attempts to define the relations between the first Christian emperor and the Church, no phrase is more frequently quoted than this obiter dictum. In the sixteenth century the French scholar Henri de Valois rendered τῶν ἐκτόϛ as if it were the genitive of τὰ ἐκτόϛ, and since then it has been the practice to regard Constantine as an ‘évèque du dehors’: the Emperor either exercised episcopal functions though not consecrated, or supervised mundane affairs (that is, the State), after the fashion of a bishop, or else held from God a temporal commission for ecclesiastical government, the bishops retaining control of dogma, ethics and discipline. Each of these three distinct interpretations is equally admissible.
