86 Marcellus the bishop PL 23, 693
Marcellus, bishop of Ancyra, flourished in the reign of Constantinus and Constantius and wrote many volumes of various Propositions and especially against the Arians. Works of Asterius and Apollinarius against him are current, which accuse him of Sabellianism. Hilary too, in the seventh book of his work Against the Arians, mentions him as a heretic, but he defends himself against the charge through the fact that Julius and Athanasius bishops of Rome and Alexandria communed with him.
Marcellus, Ancyranus episcopus, sub Constantino et Constantio principibus floruit, multaque diversarum ὑποθέσεων scripsit volumina, et 925 maxime adversum Arianos. Feruntur contra hunc Asterii et Apollinarii libri, Sabellianae eum haeresis arguentes, sed et Hilarius, in septimo adversum Arianos libro, nominis ejus, quasi haeretici meminit. Porro ille defendit, se non esse dogmatis, cujus accusatur, sed communione Julii et Athanasii, Romanae et Alexandrinae urbis pontificum, se esse munitum.
Μάρκελλος, Ἀγκυρανὸς ἐπίσκοπος, ἐπὶ Κωνσταντίνου καὶ Κωνσταντίου ἤνθησε, πολλὰ διαφόρων ὑποθέσεων γράψας τεύχη, καὶ μάλιστα κατὰ τῶν Ἀρειανῶν. Φέρονται κατ' αὐτοῦ Ἀστερίου 926 καὶ Ἀπολλιναρίου λόγοι Σαβελλιανῆς τοῦτον αἱρέσεως εὐθύνοντες, καὶ Ἱλάριος δὲ ἐν τῷ ἑβδόμω κατὰ τῶν Ἀρειανῶν λόγῳ, οἷα δὴ αἱρετικοῦ μέμνηται, ἀλλ' ἐκεῖνος ἀπολογεῖται, μὴ εἶναι οὗ κατηγορεῖται δόγματος, τῇ κοινωνίᾳ πεποιθώς Ἰουλίου καὶ Ἀθανασίου Ῥώμης καὶ Ἀλεξανδρείας ἐπισκόπων.
