_Teaching._ 'Having said beforehand all these things, baptize ye in the name of the Father, and of the Son, and of the Holy Ghost in living water.'[194] [Footnote 194: Teaching, ch. vii.; Matt. 28. 19.] The passage from Barnabas deserves special mention, since here we have words which only occur in our Gospels, introduced with the phrase _as it is written_, which is only used of Scripture quotations. And this shows conclusively that at the time of the writer, some Gospel containing these words must have been well known, and considered of high authority. And the attempts to explain it away as being from the Book of Esdras,[195] where the words are, 'There be many created, but few shall be saved;' or else as an error on the part of the writer, who thought they came somewhere in the Old Testament, are quite inadmissible. [Footnote 195: 2 Esdr. 8. 3.] But it may be said, may not all these quotations be from some _Lost Gospel_? Of course they may. It is always possible to refer quotations not to the only book in which we know they do occur, but to some imaginary book in which they might occur. There is, however, no need to do so in this case, as all the evidence points the other way. Though, even if we do, it does not materially affect the argument; for while it weakens the evidence for our Gospels, it increases that for the _facts_ which they record; and this is the important point. Suppose, for instance, the passage in Ignatius was not taken from St. Luke's, but from some _Lost_ Gospel. It could not then be quoted to show that St. Luke's Gospel was known to Ignatius. But it would afford additional evidence that Christ really did rise from the dead, that when He appeared to His Apostles, they at first thought He was a spirit; and that He took the obvious means of convincing them, by asking them to handle His Body. All this would then be vouched for, not only by St. Luke's Gospel; but also by some _other_ early Christian writing, which as Ignatius quotes it in A.D. 110 must certainly have been written in the first century, and must have been considered by him as conclusive evidence. For he is careful to distinguish between what he thus _knows_ (that Christ had a Body after His Resurrection) and what he merely _believes_ (that He has one now). And the same applies in other cases.
