The Alogi (ἄλογοι), also called Alogoi or Alogians, were a group of heterodox Christians in Asia Minor that flourished c. 200 CE, and taught that the Gospel of John and the Apocalypse of John (Book of Revelation) were not the work of the Apostle, but his adversary Cerinthus. What we know of them is derived from their doctrinal opponents, whose literature is extant, particularly St. Epiphanius of Salamis. It was Epiphanius who coined the name "Alogi" as a word play suggesting that they were both illogical (anti-logikos) and they were against the Christian doctrine of the Logos. While Epiphanius does not specifically indicate the name of its founder, Dionysius Bar-Salibi, citing a lost work of Hippolytus (Capita Adversus Caium), writes in his commentary on the Apocalypse,Hippolytus the Roman says: A man appeared, named Caius, saying that the Gospel is not by John, nor the Apocalypse but that it is by Cerinthus the heretic.Cf. Eusebius, Ecclesiastical History, 3.28.2According to fourth century church historian Eusebius of Caesarea, Caius was a churchman of Rome who wrote during the time of Pope Zephyrinus, and had published a disputation with Proclus, a Montanist leader in Rome. Beliefs “St. Epiphanius (Haer. LI) gives a long account of the party of heretics who arose after the Cataphrygians, Quartodecimans, and others, and who received neither the Gospel of St. John nor his Apocalypse.”; they instead attributed the two New Testament books to the Gnostic Cerinthus, who was actually an enemy of John the Apostle. Regarding their beliefs, Epiphanius asserts that the Alogians denied the continuation of spiritual gifts in the church in opposition to the Montanists. They explicitly deny the Logos doctrine in John chapter 1 and they deny Johannine authorship by comparing his Gospel with the synoptic Gospels. Their methodology can be seen in the surviving fragments of Hippolytus of Rome's refutation, Capita Adversus Caium, preserved in Bar-Salibi's Commentary on the Apocalypse. Their comparative method was considered very foolish in Epiphanius’ opinion who derided them as "without reason". Syriacist John Gwynn, who published these fragments in English, likewise indicates that, "The objections of Caius are . . . those of a somewhat captious critic, and indicates little breadth of scriptural learning or of eschatological conceptions". Epiphanius argues that Cerinthus could not have written the Gospel of John because whereas Cerinthus denied the deity of Christ, the Gospel taught Christ's Godhead. Epiphanius contemplates that they may not reject
