1 Corinthians 15:1-8

AND NOW let me remind you [since it seems to have escaped you], brethren, of the Gospel (the glad tidings of salvation) which I proclaimed to you, which you welcomed and accepted and upon which your faith rests, And by which you are saved, if you hold fast and keep firmly what I preached to you, unless you believed at first without effect and all for nothing. For I passed on to you first of all what I also had received, that Christ (the Messiah, the Anointed One) died for our sins in accordance with [what] the Scriptures [foretold], [Isa. 53:5-12.] That He was buried, that He arose on the third day as the Scriptures foretold, [Ps. 16:9, 10.] And [also] that He appeared to Cephas (Peter), then to the Twelve. Then later He showed Himself to more than five hundred brethren at one time, the majority of whom are still alive, but some have fallen asleep [in death]. Afterward He was seen by James, then by all the apostles (the special messengers), And last of all He appeared to me also, as to one prematurely and born dead [no better than an unperfected fetus among living men].
