Κέρδων δé τις ἀπὸ τῶν περὶ τὸν Σίμωνα τὰς ἀφορμὰς λαβὼν καὶ ἐπιδημήσας ἐν τῇ Ῥώμῃ ἐπὶ Ὑγίνου, ἔννατον κλῆρον τῆς ἐπισκοπικῆς διαδοχῆς ἀπὸ τῶν άποστόλων ἔχοντος, ἐδίδαξε τὸν ὑπὸ τοῦ νόμου καὶ προφητῶν κεκηρυγμένον Θεόν, μὴ εἷναι πατέρα τοῦ Κυρίου ἡμῶν Ἰησοῦ Χρίστοῦ, τὸν μὲν yὰp γνωρίζεσθαι, τὸν δὲ ἀγνὢτα εἷναι· καὶ τὸν μὲν δίκαιον, τὸν δὲ ἀγαθόν ὑπάρχειν.

Διαδεξάμενος δὲ αὐτὸν Μαρκίων ὁ Ποντικός, ηὔξησε τὸ διδασκαλεῖον, ἀπηρυθριασμενως βλασφημῶν eum qui a lege et prophetis annuntiatus est Deus; malorum factorem et bellorum concupiscentem et inconstantem quoque sententia et contrarium sibi ipsum dicens. Iesum autem ab eo Patre, qui est super mundi fabricatorem Deum, venientem in Iudaeam temporibus Pontii Pilati praesidis, qui fuit procurator Tiberii Caesaris, in hominis forma manifestatum his, qui in Iudaea erant, dissolventem prophetas et legem et omnia opera eius Dei, qui mundum fecit, quem et Cosmocratorem dicit. Et super haec id quod est secundum Lucam evangelium circumcidens et omnia, quae sunt de generatione Domini conscripta, auferens, et de doctrina sermonum Domini multa auferens, in quibus manifestissime conditorem huius universitatis suum Patrem confitens Dominus conscriptus est; semetipsum esse veraciorem, quam sunt hi, qui evangelium tradiderunt, apostoli, suasit discipulis suis, non evangelium, sed particulam evangelii tradens eis. Similiter autem et apostoli Pauli epistolas abscidit, auferens quaecunque manifeste dicta sunt ab apostolo de eo Deo, qui mundum fecit, quoniam hic Pater Domini nostri Iesu Christi, et quaecunque ex propheticis memorans apostolus docuit, praenuntiantibus adventum Domini.

One Cerdon, who had taken his principles from the school of Simon, and stayed in Rome in the time of Hyginus, who held the ninth place of the episcopal succession from the Apostles – he taught that the God preached by the law and prophets is not the Father of our Lord Jesus Christ; for the former is known, but the latter unknown, and the former is by nature righteous, but the other good.

And Marcion of Pontus succeeding him developed the school, blaspheming shamelessly him who is proclaimed as God by the law and the prophets; calling him a maker of evils and a lover of wars, unsettled of purpose also, and inconsistent with himself. [He said] however that Jesus coming from the Father, who is above the God who made the world, into Judaea in the times of the governor Pontius Pilate, procurator of Tiberius Caesar, was manifested in the form of a man to those that were in Judaea, destroying the prophets and the law, and all the works of the God who made the world, whom he also calls Cosmocrator. Besides this, by mutilating the Gospel which is according to Luke, and removing all that refers to the generation of the Lord, and removing many passages of the teaching of the Lord's discourses, in which the Lord is recorded as very plainly confessing the framer of this universe to be his own Father, Marcion has persuaded his disciples that he is himself truer than those Apostles who delivered the Gospel; so he delivers to them not the Gospel, but a part of the Gospel. But likewise he has cut down also the Epistles of the Apostle Paul, removing all that is plainly said by the Apostle concerning the God that made the world, that he is the Father of our Lord Jesus Christ; and all that the Apostle taught by quotation from the prophetical writings which foretold the coming of the Lord.
