In order to show this with such brevity as is necessary in the present book, and at the same time to guard ourselves against every danger of prejudice in the investigation, we shall for this occasion assume hypothetically that all, even the most extreme, assertions of Biblical criticism as to the authenticity and inauthenticity of the books of the New Testament, and as to the difference of their component parts and the time of their composition, are correct and proven; and see what then remains established. In the first place, it is an acknowledged fact, that Peter first, then the eleven apostles at different times, and between these more than five hundred "brethren" (_i.e._, nearly or fully all who had preserved their {336} attachment to the Lord till his death), saw the appearances of the risen one, a few days after his death; and, indeed, under the most different circumstances, and under mental conditions in which they did not at all expect any such second appearance. We have, in regard to this, the most authentic written evidence of the apostle Paul, in the fifteenth chapter of his first letter to the Corinthians: a letter whose authenticity no criticism has dared to doubt. This letter was written in the spring of 58: and Paul himself had already been changed from a persecutor into a believer in Christ in the year 36--_i.e._, one year after the death of Jesus, which took place in 35; he went to Jerusalem in 39, and here everything was related to him by Peter, as we know from his letter (likewise not contested) to the Galatians. Thus the authentic information of the man, who in 58 collected the historical proofs of the reality of the resurrection of Jesus for his Corinthian Christians, goes back to four years after the death of Jesus, and to the personal witnesses of the appearances; as in that letter he also refers to the fact that "many of these five hundred brethren are still living." Moreover, it is an established fact, that the first written evidences of the evangelical history from which our canonical gospels subsequently originated, likewise contained accounts of the appearance of the risen one. Finally, it is an established fact that, from the very beginning, the whole meaning of evangelical preaching turned on the two facts of the death and of the resurrection of Jesus, as on the two cardinal points of all preaching of salvation; also that all the faith of those who embraced the Gospel was founded upon these two facts, as upon the historical fundamentals of the {337} salvation which comes from Jesus; and that thus Christianity, with all its effects, which have unhinged the old world and diffused streams of blessing over mankind, has its historical basis in faith in the death of Jesus and his resurrection. This is our historical chain of proof. And that evidence which gives certainty to its most important link, on which everything depends--the _appearance_ of the risen one--is the entire
