“The Fourth Gospel does not pretend to be a biography of Jesus; it is a presentation of Christ from the theological point of view, as the divine Logos or Word, creator of the world and redeemer of mankind. It contradicts the synoptic gospels in a hundred details and in its general picture of Christ. The half-Gnostic character of the work, and its emphasis on metaphysical ideas, have led many Christian scholars to doubt that its author was the apostle John. Experience suggests, however, that an old tradition must not be too quickly rejected; our ancestors were not all fools.”
Will Durant Caesar and Christ
