"Now I remind you, brothers, of the good news that I declared to you, which you also accepted, and for which you have taken your stand.Through it you are also being saved if you hold firmly to the good news I declared to you,unless you became believers for nothing.For among the first things I handed on to you was what I also received, that Christ died for our sins according to the Scriptures;and that he was buried, yes, that he was raised up on the third day according to the Scriptures;and that he appeared to Ceʹphas, and then to the Twelve.After that he appeared to more than 500 brothers at one time, most of whom are still with us,though some have fallen asleep in death.After that he appeared to James,then to all the apostles.But last of all he appeared also to me as if to one born prematurely.(...)Whether, then,it is I or they, this is the way we preach, and this is the way you believed." 1 Corinthians 15:1-11
