1 Corinthians 15:32

If after the manner of men I fought with beasts at Ephesus, what doth it profit me? If the dead are not raised, let us eat and drink, for tomorrow we die.

Fought with beasts at Ephesus ... Scholars are divided on whether to construe this metaphorically as a reference to great persecutions and dangers Paul endured at Ephesus, or as mention of an event in which the apostle actually did so. There is no way to know, for plausible and weighty arguments may be deployed on either side of the question. The feeling here is that this refers to actual conflict; and Luke's not mentioning it does not deny it. There were several shipwrecks that Luke did not mention, along with many other hardships of the grand apostle. Besides that, there is a glimpse of some mortal danger to Paul from which he was saved by Priscilla and Aquila (Romans 16:4), for which the Gentile churches throughout the Roman Empire gave thanks to God; and that mystery could be related to this. In any case, the point should not be forgotten: what was the profit of such danger and suffering endured for the sake of Christianity, if there is no resurrection of the dead?

Eat and drink, for tomorrow we die ... This was Epicureanism; and Paul's words here may be construed as saying that paganism is as good as Christianity if the doctrine of the resurrection is denied.
