1 Corinthians 15:4

After these points, Celsus proceeds to bring against the Gospel narrative a charge which is not to be lightly passed over, saying that "if Jesus desired to show that his power was really divine, he ought to have appeared to those who had ill-treated him, and to him who had condemned him, and to all men universally." For it appears to us also to be true, according to the Gospel account, that He was not seen after His resurrection in the same manner as He used formerly to show Himself — publicly, and to all men. But it is recorded in the Acts, that "being seen during forty days," He expounded to His disciples "the things pertaining to the kingdom of God." [Acts 1:3] And in the Gospels it is not stated that He was always with them; but that on one occasion He appeared in their midst, after eight days, when the doors were shut [John 20:26], and on another in some similar fashion. And Paul also, in the concluding portions of the first Epistle to the Corinthians, in reference to His not having publicly appeared as He did in the period before He suffered, writes as follows: "For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the Scriptures; and that He was seen of Cephas, then of the twelve: after that He was seen of above five hundred brethren at once, of whom the greater part remain unto the present time, but some are fallen asleep. After that He was seen of James, then of all the apostles. […]

"And that he was buried." And this also confirms the former topics, for that which is buried is doubtless a body. And here he no longer adds, "according to the Scriptures." He had wherewithal, nevertheless he adds it not. For what cause? Either because the burial was evident unto all, both then and now, or because the expression, "according to the Scriptures," is set down of both in common. Wherefore then doth he add, "according to the Scriptures," in this place, "and that He rose on the third day according to the Scriptures," and is not content with the former clause, so spoken in common? Because this also was to most men obscure: wherefore here again he brings in "the Scriptures" by inspiration, having so conceived this thought so wise and divine. How is it then that he doth the same in regard of His death? Because in that case too, although the cross was evident unto all and in the sight of all He was stretched upon it; yet the cause was no longer equally so. The fact indeed of his death all knew, but that He suffered this for the sins of the world was no longer equally known to the multitude. Wherefore he brings in the testimony from the Scriptures. This however hath been sufficiently proved by what we have said. But where have the Scriptures said that He was buried, and on the third day shall rise again? By the type of Jonah which also Himself alleges, saying, "As Jonah was three days and three nights in the whale's belly, so shall also the Son of Man be three days and three nights in the heart of the earth." By the bush in the desert. For even as that burned, yet was not consumed, so also that body died indeed, but was not holden of death continually. And the dragon also in Daniel shadows out this. […]

On the third day He rose from the dead, resuming the body which He had previously vivified, yet not such a body as it had been before: for before it was passible and mortal, but after He rose, it was impassible and immortal, living perpetually. …
