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, 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 last of all He was seen of me also, as of one born out of due time.(1Cor15:8-13)”
