For I passed on to you as most important what I also received:
that Jesus 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 Cephas,
then to the Twelve.
Then He appeared to over 500 brothers at one time;
most of them are still alive,
but some have fallen asleep.
Then He appeared to James,
then to all the apostles.
Last of all, as to one abnormally born,
He also appeared to me.
1 Corinthians 15:3-8
