1 Corinthians 15:1-11 New Revised Standard Version (NRSV)
The Resurrection of Christ
15 Now I would remind you, brothers and sisters,[a] of the good news[b] that I proclaimed to you, which you in turn received, in which also you stand, 2 through which also you are being saved, if you hold firmly to the message that I proclaimed to you—unless you have come to believe in vain.
3 For I handed on to you as of first importance what I in turn had received: that Christ died for our sins in accordance with the scriptures, 4 and that he was buried, and 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 brothers and sisters[c] at one time, most of whom are still alive, though some have died.[d] 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. 9 For I am the least of the apostles, unfit to be called an apostle, because I persecuted the church of God. 10 But by the grace of God I am what I am, and his grace toward me has not been in vain. On the contrary, I worked harder than any of them—though it was not I, but the grace of God that is with me. 11 Whether then it was I or they, so we proclaim and so you have come to believe.
