Basilides carries us back to an early date in point of time. He taught at Alexandria in the reign of Hadrian (117-137 A.D.). Hippolytus expounds at some length, and very much in their own words, the doctrines of Basilides and his school. There is a somewhat similar account by Epiphanius, and more incidental allusions in Clement of Alexandria and Origen.
The notices that have come down to us of the writings of Basilides are confusing. Origen says that 'he had the effrontery to compose a Gospel and call it by his own name' [Endnote 188:1]. Eusebius quotes from Agrippa Castor, a contemporary and opponent from the orthodox side, a statement that 'he wrote four and twenty books (presumably of commentary) upon the Gospel' [Endnote 189:1]. Clement of Alexandria gives rather copious extracts from the twenty-third of these books, to which he gave the name of 'Exegetics' [Endnote 189:2].
Tischendorf assumes, in a manner that is not quite so 'arbitrary and erroneous' [Endnote 189:3] as his critic seems to suppose, that this Commentary was upon our four Gospels. It is not altogether clear how far Eusebius is using the words of Agrippa Castor and how far his own. If the latter, there can be no doubt that he understood the statement of Agrippa Castor as Tischendorf understands his, i.e. as referring to our present Gospels; but supposing his words to be those of the earlier writer, it is possible that, coming from the orthodox side, they may have been used in the sense which Tischendorf attributes to them. There can be no question that Irenaeus used [Greek: to euangelion] for the canonical Gospels collectively, and Justin Martyr may perhaps have done so. Tischendorf himself does not maintain that it refers to our Gospels exclusively. Practically the statements in regard to the Commentary of Basilides lead to nothing.
Neither does it appear any more clearly what was the nature of the Gospel that Basilides wrote. The term [Greek: euangelion] had a technical metaphysical sense in the Basilidian sect and was used to designate a part of the transcendental Gnostic revelations. The Gospel of Basilides may therefore, as Dr. Westcott suggests, reasonably enough, have had a philosophical rather than a historical character. The author of 'Supernatural Religion' censures Dr. Westcott for this suggestion [Endnote 189:4], but a few pages further on he seems to adopt it himself, though he applies it strangely to the language of Eusebius or Agrippa Castor and not to Basilides' own work.
In any case Hippolytus expressly says that, after the generation of Jesus, the Basilidians held 'the other events in the life of the Saviour followed as they are written in the Gospels' [Endnote 190:1]. There is no reason at all to suppose that there was a breach of continuity in this respect between Basilides and his school. And if his Gospel really contained substantially the same events as ours, it is a question of comparatively secondary importance whether he actually made use of those Gospels or no.
It is rather remarkable that Hippolytus and Epiphanius, who furnish the fullest accounts of the tenets of Basilides (and his followers), say nothing about his Gospel: neither does Irenaeus or Clement of Alexandria; the first mention of it is in Origen's Homily on St. Luke. This shows how unwarranted is the assumption made in 'Supernatural Religion' [Endnote 190:2] that because Hippolytus says that Basilides appealed to a secret tradition he professed to have received from Matthias, and Eusebius that he set up certain imaginary prophets, 'Barcabbas and Barcoph,' he therefore had no other authorities. The statement that he 'absolutely ignores the canonical Gospels altogether' and does not 'recognise any such works as of authority,' is much in excess of the evidence. All that this really amounts to is that neither Hippolytus nor Eusebius say in so many words that Basilides did use our Gospels. It would be a fairer inference to argue from their silence, and still more from that of the 'malleus haereticorum' Epiphanius, that he did not in this depart from the orthodox custom; otherwise the Fathers would have been sure to charge him with it, as they did Marcion. It is really I believe a not very unsafe conclusion, for heretical as well as orthodox writers, that where the Fathers do not say to the contrary, they accepted the same documents as themselves.
The main questions that arise in regard to Basilides are two: (1) Are the quotations supposed to be made by him really his? (2) Are they quotations from our Gospels?
The doubt as to the authorship of the quotations applies chiefly to those which occur in the 'Refutation of the Heresies' by Hippolytus. This writer begins his account of the Basilidian tenets by saying, 'Let us see here how Basilides along with Isidore and his crew belie Matthias,' [Endnote 191:1] &c. He goes on using for the most part the singular [Greek: phaesin], but sometimes inserting the plural [Greek: kat' autous]. Accordingly, it has been urged that quotations which are referred to the head of the school really belong to his later followers, and the attempt has further been made to prove that the doctrines described in this section of the work of Hippolytus are later in their general character than those attributed to Basilides himself. This latter argument is very fine drawn, and will not bear any substantial weight. It is, however, probably true that a confusion is sometimes found between the 'eponymus,' as it were, of a school and his followers. Whether that has been the case here is a question that we have not sufficient data for deciding positively. The presumption is against it, but it must be admitted to be possible. It seems a forced and unnatural position to suppose that the disciples would go to one set of authorities and the master to another, and equally unnatural to think that a later critic, like Hippolytus, would confine himself to the works of these disciples and that in none of the passages in which quotations are introduced he has gone to the fountain head. We may decline to dogmatise; but probability is in favour of the supposition that some at least of the quotations given by Hippolytus come directly from Basilides.
Some of the quotations discussed in 'Supernatural Religion' are expressly assigned to the school of Basilides. Thus Clement of Alexandria, in stating the opinion which this school held on the subject of marriage, says that they referred to our Lord's saying, 'All men cannot receive this,' &c.
