Is the resurrection a basic doctrine of the Christian faith?
Yes. The resurrection is a basic doctrine of the Christian faith. First Corinthians chapter 15 presents it as foundational, and Paul explains that resurrections occur in order: Christ as the First Fruits, then those who are Christ's at His coming.
Les explains that the resurrection is basic to the Christian faith. In 1 Corinthians chapter 15, after discussing the doctrine of the resurrection, Paul shifts gears at verse 20 to break down how the resurrections will take place. They are not all at one event. First came the First Fruits when Christ rose from the dead, along with those Jewish believers who came out of the graves in Matthew 27. Then, as 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—the believers of the church age. Les also connects this to Acts and Galatians, showing God's transition to Paul's ministry to the Gentiles.
But now is Christ risen from the dead, and become the firstfruits of them that slept.
