For my own part I do not feel able to speak with quite the same confidence, and yet upon the whole the evidence, which on a single instance might seem to incline the other way, does appear to favour the conclusion that Clement used our present Canonical Gospels.

There is not, so far as I am aware, any reason to complain of the statement of opinion in 'Supernatural Religion' as to the date of the so-called Epistle of Barnabas.

Arguing then entirely from authority, we may put the _terminus ad quem_ at about 130 A.D.The only writer who is quoted as placing it later is Dr.
Donaldson, who has perhaps altered his mind in the later edition of his work, as he now writes: 'Most (critics) have been inclined to place it not later than the first quarter of the second century, and all the indications of a date, though very slight, point to this period' [Endnote 71:1].
The most important issue is raised on a quotation in c.

iv, 'Many are called but few chosen,' in the Greek of the Codex Sinaiticus [Greek: [prosechomen, maepote, hos gegraptai], polloi klaetoi, oligoi de eklektoi eurethomen.] This corresponds exactly with Matt.xxii.14, [Greek: polloi gar eisin klaetoi, oligoi de eklektoi].

The passage occurs twice in our present received text of St.Matthew, but in xx.

16 it is probably an interpolation.
There also occurs in 4 Ezra (2 Esdras) viii.
