In fact, when the apostle Paul spoke at the Areopagus, likely the Epicureans were among those who took issue with Paul over the doctrine of the resurrection.—Acts 17:18, 31, 32; 1 Corinthians 15:12-14.
... At the time of Paul’s writing his first letter to the Corinthians, some of them had already lost faith in the resurrection.—1 Corinthians 15:12-19.
