1 Corinthians 15 has been the battle field for the debate regarding the controlling subject of the letter of 1 Corinthians, since it contains Paul’s argument about the resurrection-the single most important subject of Christianity. 1 Corinthians 15:1-11 reveals Paul’s answer to the Corinthians’ question of the validity of physical resurrection. So, some argued that this passage is about Paul’s defense of the Christian doctrine of the bodily resurrection, while others argued that it is more about his defense of the apostleship. It is true that as he says in 1 Corinthians 11:1-2, he delivered with urgency the tradition of Jesus’ death, burial, resurrection and appearance, to the Corinthians as the essential element of his teaching in his Corinthian mission. However, Paul quickly adds his name to the list of those eyewitnesses of the risen Lord (vv. 3-8). By doing so, he can argue that his apostleship is also based upon the same experience of the risen Lord that 12 apostles and James have. However, this is not the end of the story. While Paul is eager to defend the validity of the bodily resurrection of Jesus and then his apostleship, what is at risk from Paul’s perspectives is neither the truth claim of resurrection, nor his apostleship, but the wellbeing of the Corinthian church. Since it is none other than Paul himself that established the Corinthian church on the foundation of Jesus, if his apostleship and the Gospel he preached are found invalid, then, the Corinthian church will also be found invalid. Therefore, I argue that the edification of the Corinthian church is the primary agenda behind his defense of the resurrection and the apostleship in 1 Corinthians 15:1-11.
