This video finishes the thought Paul is trying to convey in these verses (verses 20 & 21). The Lord in this passage is trying to pinpoint a table of devils and a cup of devils. It is a cup and table that is like the real communion (verses 16 & 17) of Christ, except it's a counterfeit that actually sacrifices to devils, according to the Bible. Watch how the verses point directly to the Mass of the Roman Catholic Church.
