Now, those four evangelists whose names have gained the most remarkable circulation ¹ over the whole world, and whose number has been fixed as four,--it may be for the simple reason that there are four divisions of that world through the universal length of which they, by their number as by a kind of mystical sign, indicated the advancing extension of the Church of Christ,--are believed to have written in the order which follows: first Matthew, then Mark, thirdly Luke, lastly John. Hence, too, [it would appear that] these had one order determined among them with regard to the matters of their personal knowledge and their preaching [of the gospel], but a different order in reference to the task of giving the written narrative. As far, indeed, as concerns the acquisition of their own knowledge and the charge of preaching, those unquestionably came first in order who were actually followers of the Lord when He was present in the flesh, and who heard Him speak and saw Him act; and [with a commission received] from His lips they were despatched to preach the gospel. But as respects the task of composing that record of the gospel which is to be accepted as ordained by divine authority, there were (only) two, belonging to the number of those whom the Lord chose before the passover, that obtained places,--namely, the first place and the last. For the first place in order was held by Matthew, and the last by John. And thus the remaining two, who did not belong to the number referred to, but who at the same time had become followers of the Christ who spoke in these others, were supported on either side by the same, like sons who were to be embraced, and who in this way were set in the midst between these twain.
