1 CORINTHIANS 10:20-21 No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons. You cannot drink the cup of the Lord and the cup of demons too; you cannot have a part in both the Lord's table and the table of demons.
BARNES' NOTES The word "demons," among the Jews, was employed only to designate evil beings. It is not implied in their writings to good angels or to blessed spirits, but to evil angels, to idols, to false gods.
You are solemnly dedicated to Christ; and the homage due to him should not be divided with homage offered to devils, or to imaginary beings.
