Do I mean then that food sacrificed to an idol is anything, or that an idol is anything? 20 No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons. (I Corinthians 10:19-20)
In the verses above the Apostle Paul explains why it is inappropriate for Christians to participate in the ceremonies of other religions. Some would argue that it doesn’t matter if we eat food that is sacrificed to idols, because we know that the pagan gods don’t really exist anyway. However, these pagan gods are not neutral: the ideas the represent are evil, even though the deities themselves do not really exist. Paul explains that there are demonic powers behind false religions. These religions were created by the forces of evil in order to seduce humans. We should keep away from them, since the are harmful, and we should not in any way endorse them by participating in their rites.
