Chapter XXV.—The Heresy of Cerdon. But one Cerdon 897 himself also, taking occasion in like manner from these (heretics) and Simon, affirms that the God preached by Moses and the prophets was not Father of Jesus Christ. For (he contends) that this (Father) had been known, whereas that the Father of Christ 898 was unknown, and that the former was just, but the latter good. And Marcion corroborated the tenet of this (heretic) in the work which he attempted to write, and which he styled Antitheses . 899 And he was in the habit, (in this book,) of uttering whatever slanders suggested themselves to his mind against the Creator of the universe. In a similar manner likewise (acted) Lucian, 900 the disciple of this (heretic). 897     Irenæus, i. 27; Eusebius (who here gives Irenæus’ Greek), Hist. Ecclesiast ., iv. 2; Epiphanius, c. xli.; Theodoret, Hær. Fab ., i. 24; and Philastrius, c. xliv. 898     Hippolytus follows Irenæus but introduces some alterations. 899     ᾽Αντιθέσεις .  This is the emendation proposed by the Abbe Cruice. The textual reading is ἀντιπαραθέσεις (comparisons). 900     See [ ut supra , p. 353], Tertullian, Præscript ., c. li., and Epiphanius, Hær ., c. xliii.
