45. Marcion, his [i.e. Cerdon's] disciple, originally from Pontus, from the city of Sinope, came to the city of Rome. Staying there he promoted a vicious heresy, and in his discussions with the holy presbyters of the Catholic church he exposed the nature of his deathly error saying that: "what does it mean," he said "what is written in the Gospel about the Lord saying: No man puts an unused piece of cloth on an old garment, nor puts he new wine into old skins, otherwise the skins will break and wine will be spilled (cf. Luke 5: 36-37). And again, "For there is no good tree that brings forth evil fruit; nor an evil tree that brings forth good fruit" (cf. Luke 6:43)." Having not accepted the interpretation given by the holy presbyters, he did not comply with truth but rather confirmed the lie of his teacher Cerdon, and similarly to him, he announced that there is the good god and the evil one. That Christ appeared only in imaginary way, that is if a ghost, and also his Passion was unreal because Marcion did not believe in the true flesh [of Christ]. He accepted only the Gospel according to Luke. [He did not accept] any other Gospel nor the Pauline epistles, except of the ones to Timothy and Titus. What they say about Christ as the true God, he omitted; what the Scriptures say about Christ as a man, these chapters he accepted, and he did not professed that Christ is the judge of all. He was defeated and forced to run by John the Evangelist and the holy presbyters of the city of Ephesus, and he spread this heresy in Rome.
