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 (needless to us, or to anybody apart from the people themselves), constant occupation with questions which we can only dimly discover from Paul’s answers. The letters are genuine letters—written for the occasion to particular people, and not meant for us. The German scholar, Norden, in his Kunstprosa, says there is much in Paul that he does not understand, but he catches in him again after three hundred years that note of life that marks the great literature of Greece. That is not easily forged. Luther and Erasmus were right when they said—each of them has said it, however it happened—that Paul “spoke pure flame.” The letters, and the theology and its influence, establish at once Paul’s claim to be a historical character. We may then ask, how a man of his ability failed to observe that a non-historical Jesus, a pure figment, was being palmed off on him—on a contemporary, it should be marked—and by a combination of Jesus’ own disciples with earlier friends of Paul, who were trying to exterminate them. Paul knew priests and Pharisees; he knew James and John and Peter; and he never detected that they were in collusion, yes, and to the point of martyring Stephen—to impose on him and on the whole world a non-historical Jesus. To such straits are we brought, if Jesus never existed. History becomes pure nonsense, and knowledge of historical fact impossible; and, it may be noted, all knowledge is abolished if history is beyond reach.
