Triage

When it comes to theological triage, Paul calls the Gospel (the story of Jesus and its climactic moments) of first importance:

“For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas, then to the twelve.”

I strongly suspect that Paul here defines what he means by “raised on the third day in accordance with the Scriptures” as he has done something similar with the cross in the beginning of the letter.
