15 Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, ² by which also you are saved, if you hold fast the word which I preached to you, 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 according to the Scriptures, ⁴ and that He was buried, and that He was raised on the third day according to the Scriptures, ⁵ and that He appeared to Cephas, then to the twelve. ⁶ After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; ⁷ then He appeared to James, then to all the apostles; ⁸ and last of all, as to one untimely born, He appeared to me also. ⁹ For I am the least of the apostles, and not fit 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 did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me. ¹¹ Whether then it was I or they, so we preach and so you believed.
