A great deal of the discrepancy observable in the Gospels arises from omission; from a fact or a passage of Christ’s life being noticed by one writer which is unnoticed by another. Now, omission is at all times a very uncertain ground of objection. We perceive it, not only in the comparison of different writers, but even in the same writer when compared with himself. There are a great many particulars, and some of them of importance, mentioned by Josephus in his Antiquities, which, as we should have supposed, ought to have been put down by him in their place in the Jewish Wars. (Lardner, part i. vol. ii. p. 735, et seq.) Suetonius, Tacitus, Dio Cassius, have, all three, written of the reign of Tiberius. Each has mentioned many things omitted by the rest, (Lardner, part i. vol. ii. p. 743.) yet no objection is from thence taken to the respective credit of their histories. We have in our own times, if there were not something indecorous in the comparison, the life of an eminent person written by three of his friends, in which there is very great variety in the incidents selected by them; some apparent, and perhaps some real contradictions; yet without any impeachment of the substantial truth of their accounts, of the authenticity of the books, of the competent information or general fidelity of the writers.
But these discrepancies will be still more numerous, when men do not write histories, but memoirs: which is, perhaps, the true name and proper description of our Gospels: that is, when they do not undertake, nor ever meant to deliver, in order of time, a regular and complete account of all the things of importance which the person who is the subject of their history did or said; but only, out of many similar ones, to give such passages, or such actions and discourses, as offered themselves more immediately to their attention, came in the way of their inquiries, occurred to their recollection, or were suggested by their particular design at the time of writing.
