But the distinction between Christian and secular writers is not one that will weigh much with a serious historian. Until we have reason to distinguish between book and book, the evidence must be treated on exactly the same principles. To say abruptly that, because Luke was a Christian and Suetonius a pagan, Luke is not worthy of the credence given to Suetonius, is a line of approach that will most commend itself to those who have read neither author. To gain a real knowledge of historical truth, the historian’s methods must be slower and more cautious, he must know his author intimately—his habits of mind, his turns of style, his preferences, his gifts for seeing the real issue—and always the background, and the ways of thinking that prevail in the background. An ancient writer is not necessarily negligible because he records, and perhaps believes, miracles or marvels or omens which a modern would never notice. It is bad criticism that has made a popular legend of the unreliable character of Herodotus. As our knowledge of antiquity grows, and we become able to correct our early impressions, the credit of Herodotus rises steadily, and to-day those who study him most closely have the highest opinion of him.
We may, then, without prejudice, take the evidence of Paul of Tarsus on the historicity of Jesus, and examine it. If we are challenged as to the genuineness of Paul’s epistles, let us tell our questioner to read them. Novels have been written in the form of correspondence; but Paul’s letters do not tell us all that a novelist or a forger would—there are endless gaps, needless references to unknown persons
