1 Corinthians 15:1, 3-4

Let me now remind you, dear brothers and sisters, of the Good News I preached to you before. You welcomed it then, and you still stand firm in it.

I passed on to you what was most important and what had also been passed on to me. Christ died for our sins, just as the Scriptures said. He was buried, and he was raised from the dead on the third day, just as the Scriptures said.
