A.T. Robertson Commentary 1 Corinthians 15:12

"Now if Christ is preached that he hath been raised from the dead, how say some among you that there is no resurrection of the dead?" — 1 Corinthians 15:12 (ASV)

Is preached (κηρυσσετα). Personal use of the verb, Christ is preached.

How say some among you? (πως λεγουσιν εν υμιν τινεσ?). The question springs naturally from the proof of the fact of the resurrection of Christ (verses 1-11) and the continual preaching which Paul here assumes by condition of the first class (ει--κηρυσσετα). There were sceptics in Corinth, possibly in the church, who denied the resurrection of dead people just as some men today deny that miracles happen or ever did happen. Paul's answer is the resurrection of Christ as a fact. It all turns on this fact.
