The author bases his book on the Gospels; as much, let it be understood, on the synoptic Gospels as on the fourth. He confesses that he has no interest in the endless dissertations and disputes over the authority of the four Gospels, over their dates and interpolations, over their mutual relationship, and over their probabilities and sources. We have no older nor no other documents, contemporaneous, Jewish or Pagan, which would permit us to correct them or to deny them. He who goes into all this minute investigation can destroy many doctrines, but he cannot advance the true knowledge of Christ by a single step. Christ is in the Gospels, in the apostolic tradition, and in the Church. Outside of that is darkness and silence. He who accepts the four Gospels must accept them wholly, entire, syllable by syllable,—or else reject them from the first to the last and say, “We know nothing.” To attempt in these texts to differentiate what is sure from what is probable, what is historic from what is legendary, what is original from what has been added, the primitive from the dogmatic is a hopeless undertaking, which almost always ends in defeat, in the despair of the readers, who in the midst of this hubbub of contradictory systems, changing from one decade to another, end by understanding nothing and by letting it all drop. The most famous New Testament authorities agree on only one thing, that the Church was able to select in the great mass of primitive literature the oldest Gospels thought up to that time to be the most reliable. No more need be asked. In addition to the Gospels, the author of this book has had before his eyes “the Logia and the Agrapha,” which seemed to have the most evangelical flavor, and also some apocryphal texts used with judgment. And finally nine or ten modern books which he had at hand. It seems to him as well as he can judge, that he has departed sometimes from ordinary ideas and that he has painted a Christ who has not always the perfunctory features of the ordinary holy picture, but he is not sure of this nor does he value any new thing which may be in this book, written more in the hope of having it a good book than of having it a beautiful book. It is rather more likely that he has repeated things already said by others, of which he in his ignorance has never heard. In these matters, the subject, which is truth, is unchangeable and there can be nothing new except the manner of presenting it in a form more efficacious because it may be more easily grasped.
