However widely views may differ even now in the sphere of Gospel criticism, all really competent investigators agree on one point with rare unanimity: the Gospels are not historical documents in the ordinary sense of the word, but creeds, religious books, literary documents revealing the mind of the Christian community. Their purpose is consequently not to give information as to the life and teachings of Jesus which would correspond to reality, but to awaken belief in Jesus as the Messiah sent from God for the redemption of his people, to strengthen and defend that belief against attacks. And as creeds they confine themselves naturally to recounting such words and events as have any significance for the faith; and they have the greatest interest in so arranging and representing the facts as to make them accord with the content of that faith. (a) The Synoptic Jesus. Of the numerous Gospels which were still current in the first half of the second century, as is well known, only four have come down to us. The others were not embodied by the Church in the Canon of the New Testament writings, and consequently fell into oblivion. Of these at most a few names and isolated and insignificant fragments remain to us. Thus we know of a Gospel of Matthew, of Thomas, of Bartholomew, Peter, the twelve apostles, &c. Of our four Gospels, two bear the names of apostles and two the names of companions and pupils of apostles, viz., Mark and Luke. In this, of course, it is in no way meant that they were really written by these persons. According to Chrysostom these names were first assigned to them towards the end of the second century. And the titles do not run: Gospel of Matthew, of Mark, and so on, but "according to" Matthew, "according to" Mark, Luke, and John; so that they indicate at most only the persons or schools whose particular conception of the Gospel they represent.
