I am reminding you, brothers and sisters, of the Gospel I preached to you. The last issue that Paul addresses in his first letter to the Corinthians concerns the doctrine of the resurrection. It appears that just as was the reaction in Athens when Paul preached to them the resurrection of the dead (cf. Acts 17:30-32), there were also in Corinth those who were having problems (doubts) with the teaching that Jesus rose from the dead. The inhabitants of a cosmopolitan Corinth must have found the idea of resurrection of the dead such a repulsive idea. For their philosophical background allowed for immortality of the soul but not of the body. Paul thus writes to remind them that the doctrine of the death and resurrection of the Lord is a revealed teaching and not a human invention. Moreover, it is a tradition that has been passed down, a teaching whose credibility lies in the fact that the resurrected Jesus appeared to many among his disciples after his rising from the dead. Paul would want them to hold fast to the teaching, not for any other reason, but because their salvation depends on it. It would be too late for them to reject the teaching now, for in doing so, they reduce themselves to fools. Had they not believed in the teaching when they were evangelized? Have they now received a better teaching to warrant a change of mind? Turning their backs on a teaching they had previously believed would work against them, not for them, for it would show that they are a gullible lot. Gullible individuals are not fit for any school of thought.
