1 Corinthians 15:1-5

1Now, brothers, I want to remind you of the gospel I preached to you, which you received, and in which you stand firm. 2By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.

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 Cephas1 and then to the Twelve.
