1 Corinthians 15:5

by which also you are saved, if you hold firmly the word which I preached to you—unless you believed in vain.

For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures,

that he was buried, that he was raised on the third day according to the Scriptures,

Then he appeared to over five hundred brothers at once, most of whom remain until now, but some have also fallen asleep.

Then he appeared to James, then to all the apostles,

and last of all, as to the child born at the wrong time, he appeared to me also.
