1 Corinthians 15 creedal tradition — early apostolic testimony to the resurrection

1 Corinthians 15:3-7: Christ died for our sins, was buried, rose on the third day, appeared to Cephas (early Aramaic name for Peter — indicating early, pre-Pauline formulation), to the Twelve, to 500 brothers at once (most still alive when Paul wrote — a verifiable claim), to James, and to all the apostles. Scholars regard this as a pre-Pauline creed because of: the Aramaic name Cephas, its highly rhythmic structure designed for memorization, and the creedal formula. Paul likely received it during his Jerusalem visit three years after his conversion (Galatians 1:18-19), when he met Peter and James — the very people mentioned in the creed. Even if it's not a creed, verse 11 assumes the Corinthians already knew the Jerusalem apostles' identical proclamation, confirming the original apostles genuinely claimed the resurrection.
