Is the doctrine of the resurrection a foundational Christian doctrine?
Yes, the resurrection is basic to the Christian faith. In 1 Corinthians 15, Paul teaches the doctrine of the resurrection and explains the order: Christ the firstfruits, then those who are Christ's at His coming. This makes it foundational for believers.
Les explains that the doctrine of the resurrection is basic to the Christian faith, and the program is in 1 Corinthians 15. He notes that at verse 20 Paul shifts gears and breaks down how the resurrections will take place—not all at one event. First came the First Fruits when Christ rose from the dead, along with the Jewish believers who came out of the graves in Matthew 27. Then Paul says in verse 23, every man in his own order: first Christ, the First Fruits, and afterward those who are Christ's at His coming, which would be the believers of the church age.
But now is Christ risen from the dead, and become the firstfruits of them that slept.
