1 Corinthians 10:15

'I speak as to wise men. You judge what I say.'

He pleads now that they will think about the question. They put themselves forward as wise men, so let them use their intelligence and consider what is involved by comparing the situation with their own religious ceremonies. His argument will be that religious meals involve communion, a sharing with someone in something, a sharing in common, and that that sharing is in respect to that with which they have the meal, whether Christ, or the ancient altar, or demons. Indeed, he asks, how can they be the body of Christ and participate with demons in sharing a meal?
