This refusal to reverence the many gods that was demanded of early Christians would have included refusing to offer worship to household divinities, to the tutelary deities of cities, to the traditional gods of the various cities and peoples of the Roman world, and even to the deities that represented the empire itself, such as the goddess Roma, and who conferred legitimacy to Roman rule. Indeed, Christians were expected to treat all the many deities of the Roman world as “idols,” from the Greek term eidōlon, meaning “image” or “phantom.” That is, Christians were to treat all the various traditional gods as beings unworthy of worship, as false and deceptive entities, or, even worse, as demonic beings masquerading as deities.— Destroyer of the gods: Early Christian Distinctiveness in the Roman World, page 49–50 (emphasis original)
And you thought you had problems with your in-laws or parents! That's nothing compared to walking into the house and not acknowledging the shrine of the lares, and then announcing that they were less than gods, in fact were evil semi-divine beings! I'm sure that went over well . . . NOT!
