1 Corinthians 15:3–11

³For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, ⁴that He was buried, that He was raised on the third day according to the Scriptures, ⁵and that He appeared to Cephas^a and then to the Twelve. ⁶After that, He appeared to more than five hundred brothers at once, most of whom are still living, though some have fallen asleep. ⁷Then He appeared to James, then to all the apostles. ⁸And last of all He appeared to me also, as to one of untimely birth.

⁹For I am the least of the apostles and am unworthy to be called an apostle, because I persecuted the church of God. ¹⁰But by the grace of God I am what I am, and His grace to me was not in vain. No, I worked harder than all of them — yet not I, but the grace of God that was with me. ¹¹Whether, then, it was I or they, this is what we preach, and this is what you believed.
