7.19 · Constructions · Buildings
temple of an idol a temple or sanctuary which houses an idol The term εἰδωλεῖον may be rendered as ‘the building in which an idol is placed’ or ‘a large house in which an idol is worshiped.’ Since ‘idol’ is often rendered as ‘the statue of a god,’ εἰδωλεῖον may be rendered as ‘the building in which there is a statue of a god’ or ‘a building in which a statue of a god is worshiped.’
1 1CO 8:10 It is possible that the statement about banqueting in the temple of an idol should be understood as a process by which a person would symbolically identify himself with the deity in question. This would accordingly provide a problem for an individual who was weak in his conscience.
