1 Corinthians 10
18 Ref See Israel after the flesh: do not those who take as food the offerings of the altar take a part in the altar?
19 Ref Do I say, then, that what is offered to images is anything, or that the image is anything?
20 Ref What I say is that the things offered by the Gentiles are offered to evil spirits and not to God; and it is not my desire for you to have any part with evil spirits.
21 Ref It is not possible for you, at the same time, to take the cup of the Lord and the cup of evil spirits; you may not take part in the table of the Lord and the table of evil spirits.
