Many rabbis (mostly, if not only, non-traditional, I believe) are giving us new interpretations of the word “idolatry”. We sometimes hear that the pursuit of material possessions is worship of wealth; that objects of sentimental value, such as items that belonged to a loved one, is worship of objects; that viewing certain ideas as absolute and not subject to inquiry is worship of ideas, or idolatry of the mind; that nationalism is worship of country; that egocentrism is worship of self; that astrology is worship of the stars; that love of another human being is worship of a person; that love of pets is worship of animals; that excessive family pride is worship of ancestors; and so on.
I don't buy it. According to this view, anything you care one whit about is idolatry. So the only way to observe the commandment against idolatry would be not care at all about anything.
Is there ANYTHING in our traditional Sources about idolatry (avodah zara -- strange worship) being anything other than the worship of material objects as if they had power over your destiny?
