This Edinburgh doctoral thesis intersects with two areas of recent scholarly interest, the reception of the Gospel and/or Apocalypse of John in the second century, and the origin and character of Epiphanius’ account of eighty heresies in the Panarion. It is Epiphanius who identifies a group, whom he labels ‘Alogi’, characterised by their rejection of both the Gospel and Apocalypse of John, but a body of scholarship has supplemented this with fragmentary references in Irenaeus and Origen to disputes about the Gospel, and in Dionysius of Alexandria, Eusebius’ comments on the anti-Montanist Gaius of Rome, and later reports, notably in scholia on the Apocalypse by Dionysius bar Salibi, about Hippolytus of Rome, to the rejection of the Apocalypse and even its ascription to Cerinthus; on this rests the hypothesis of a sustained opposition to the Johannine corpus in the mid-second century which might complement other supposed evidence for discomfort regarding it in ‘orthodox circles’. Explicitly following the detailed rebuttal by Charles Hill of any such ‘orthodox Johannophobia’ (2004), T. Scott Manor subjects each of the sources to critical review, establishing that they provide no independent historical information prior to and independent of Epiphanius. In turn, Epiphanius’ own account is shown not only to be creatively derivative from the earlier references but to be deliberately crafted to attack Origen's hermeneutics and exegesis of the Gospel, perhaps at this point following anxieties by Eusebius himself. While not all may be persuaded by the attribution to Origen and his ‘school’ of some of the views later attributed to the ‘Alogi’, this is a careful and sober analysis of the sources which should help to lay the latter to rest.
