to suggest another; or at least to admit that there was something which required explanation, though this particular suggestion did not seem satisfactory. Yet if it were so, the external testimony for the truth of the Gospel history would be stronger than before. It would amount to the collective view of the first congregation of Christians, who had all immediate and personal knowledge of our Lord's miracles and death and resurrection. But perhaps the external history of the four Gospels may throw some light upon the question, if indeed we can speak of light where all is a cloud of uncertainty. It would seem as if the sources of Christianity, like the roots of all other living things, were purposely buried in mystery. There exist no ancient writings whatever of such vast moment to mankind of which so little can be authentically known. The four Gospels, in the form and under the names which they at present bear, become visible only with distinctness towards the end of the second century of the Christian era. Then it was that they assumed the authoritative position which they have ever since maintained, and were selected by the Church out of the many other then existing narratives as the supreme and exclusive authorities for our Lord's life. Irenaeus is the first of the Fathers in whom they are found attributed by name to St. Matthew, St. Mark, St. Luke, and St. John. That there were four true evangelists, and that there could be neither more nor less than four, Irenaeus had persuaded himself because there were four winds or spirits, and four divisions of the earth, for which the Church being universal required four columns; because the cherubim had four faces, to each of which an evangelist corresponded; because four covenants had been given to mankind--one before the Deluge in Adam, one after the Deluge in Noah, the third in Moses, the fourth and greatest in the New Testament; while again the name of Adam was composed of four letters. It is not to be supposed that the intellects of those great men who converted the world to Christianity were satisfied with arguments so imaginative as these; they must have had other closer and more accurate grounds for their decision; but the mere employment of such figures as evidence in any sense, shows the enormous difference between their modes of reasoning and ours, and illustrates the difficulty of deciding at our present distance from them how far their conclusions were satisfactory. Of the Gospels separately the history is immediately lost in legend.
