1 Corinthians 15:3-8

I passed on to you what I received, which is of the greatest importance: that Christ died for our sins, as written in the Scriptures; that he was buried and that he was raised to life three days later, as written in the Scriptures; that he appeared to Peter and then to all twelve apostles. Then he appeared to more than 500 of his followers at once, most of whom are still alive, although some have died. Then he appeared to James, and afterwards to all the apostles. Last of all he appeared also to me — even though I am like someone whose birth was abnormal.
