1 Corinthians 8:1-4

Now as to the question of obtaining meat which has been first sacrificed on one of the city altars (and meat is not often purchasable nowadays which has not been killed in this way). The idea of course in the minds of those who have been accustomed in the past to partake of these sacrifices is that there is some connection between the meat so sacrificed and the god to whom it has been rendered as a sacrifice. That is a very fixed idea in the minds of many, that to enter the precincts of the temples, purchase the sacrificial meat as prepared by the priests and their acolytes and take it home with you, is to subject yourself to all sorts of evil influences from the spirits, gods, devils who haunt these scenes and acts of worship.
