Or how were his disciples to have boldness in speaking of the resurrection, were they not able to say that he first died? Or how could they be believed, saying that death had first taken place and then the resurrection, had they not had as witnesses of his death the men before whom they spoke with boldness? For if, even as it was, when his death and resurrection had taken place in the sight of all, the Pharisees of that day would not believe, but compelled even those who had seen the resurrection to deny it, why, surely if these things happened in secret, how many pretexts for disbelief would they have devised? Or how could the end of death, and the victory over it, be proved unless challenging it before the eyes of all he had shown it to be dead, annulled for the future by the incorruption of his body?
