For what I received I passed on to you as of first importance: 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, and that he appeared
to Peter, and then to the Twelve. After that, he appeared to more than
five hundred of the brothers at the same time, most of whom are still living,
though some have fallen asleep. Then he appeared to James, then to all the
apostles, and last of all he appeared to me also.
Whether, then, it was I or they, this is what we preach, and this is what you
believed.
