(23) Then, again, suppose without any illness He had just concealed His body somewhere, and then suddenly reappeared and said that He had risen from the dead. He would have been regarded merely as a teller of tales, and because there was no witness of His death, nobody would believe His resurrection. Death had to precede resurrection, for there could be no resurrection without it. A secret and unwitnessed death would have left the resurrection without any proof or evidence to support it. Again, why should He die a secret death, when He proclaimed the fact of His rising openly? Why should He drive out evil spirits and heal the man blind from birth and change water into wine, all publicly, in order to convince men that He was the Word, and not also declare publicly that incorruptibility of His mortal body, so that He might Himself be believed to be the Life? And how could His disciples have had boldness in speaking of the resurrection unless they could state it as a fact that He had first died? Or how could their hearers be expected to believe their assertion, unless they themselves also had witnessed His death? For if the Pharisees at the time refused to believe and forced others to deny also, though the things had happened before their very eyes, how many excuses for unbelief would they have contrived, if it had taken place secretly? Or how could the end of death and the victory over it have been declared, had not the Lord thus challenged it before the sight of all, and by the incorruption of His body proved that henceforward it was annulled and void?
