1 Corinthians 15: 1 - 8
1 Now I would remind you, brethren, in what terms I preached to you the gospel, which you received, in which you stand,
2 by which you are saved, if you hold it fast -- unless you believed in vain.
3 For I delivered to you as of first importance what I also received, that Christ died for our sins in accordance with the scriptures,
4 that he was buried, that he was raised on the third day in accordance with the scriptures,
5 and that he appeared to Cephas, then to the twelve.
6 Then he appeared to more than five hundred brethren at one time, most of whom are still alive, though some have fallen asleep.
7 Then he appeared to James, then to all the apostles.
8 Last of all, as to one untimely born, he appeared also to me.
