Before passing on, we may, in the briefest way possible, refer to one or two other passages, with the view of further illustrating the character of the quotations in this Epistle. There are many passages cited which are not found in the Old Testament, and others which have no parallels in the New. At the beginning of the very chapter in which the words which we have just been considering occur, there is the following quotation: "It-is written: Cleave to the holy, for they who cleave to them shall be made holy,"(1) the source of which is unknown. In a previous chapter the writer says: "And our Apostles knew, through our Lord Jesus Christ, that there will be contention regarding the name, [--Greek--], office, dignity?) of the episcopate."(2) What was the writers authority for this statement? We find Justin Martyr quoting, as an express prediction of Jesus: "There shall be schisms and heresies,"(3) which is not contained in our gospels, but evidently derived from an uncanonical source,(4) a fact rendered more apparent by the occurrence of a similar passage in the Clementine Homilies, still more closely bearing upon our Epistle: "For there shall be, as the Lord said, false apostles, false prophets, heresies, desires for supremacy."(5) Hegesippus also speaks in a similar way: "From these came the {232} false Christs, false prophets, false apostles who divided the unity of the Church."(l) As Hegesippus, and in all probability Justin Martyr, and the author of the Clementines made use of the Gospel according to the Hebrews, or to Peter, it is most probable that these Gospels contained passages to which the words of the Epistle may refer.(2) It may be well to point out that the author also cites a passage from the Fourth Book of Ezra, ii. 16:(3) "And I shall remember the good day, and I shall raise you from your tombs."(4) Ezra reads: "Et resuscitabo mor-tuos de locis suis et de monumentis educam illos," &c. The first part of the quotation in the Epistle, of which we have only given the latter clause above, is taken from Isaiah xxvi. 20, but there can be no doubt that the above is from this apocryphal book,(5) which, as we shall see, was much used in the early Church. 2. We now turn to the so-called "Epistle of Barnabas," another interesting relic of the early Church, many points in whose history have considerable analogy with that of the Epistle of pseudo-Clement. The letter itself bears no author's name, is not dated from any place, and is not addressed to any special community. Towards the {233}
