1363. That 'Abram, Nahor, and Haran' were the sons of Terah and also nations that were named after them as their forefathers, and that here these sons mean forms of idolatrous worship, is clear from what has been shown above and also from the fact that 'Terah', whose sons they were, means idolatry. Which forms of idolatrous worship however are meant here by the three sons of Terah and after that by Lot, the son of Haran, becomes clear if the categories of idolatrous worship are examined. There are in general four kinds of idolatrous worship, one more interior than the next. The three more interior types are like sons of the same parent, while the fourth is like the son of the third of these. There are internal and external forms of idolatrous worship. Internal forms are those which condemn a person, external less so. The more interior a form of idolatrous worship is, the more it condemns, while the more exterior it is, the less it does so. Internal idolaters do not acknowledge God but venerate themselves and the world, and treat all their desires as idols. External idolaters however are able to acknowledge God even though they are not aware of who the God of the universe is. Internal idolaters are known by the life they have acquired for themselves; and to the extent that their life is a departure from the life of charity they are interior idolaters. External idolaters are so solely on account of their worship, and although they are indeed idolaters they are nevertheless able to have the life of charity within them. Internal idolaters are capable of profaning holy things, whereas external idolaters are not. Consequently to guard against the profaning of holy things, external idolatry is permitted, as may become clear from what has been stated already in 571, 582, and above at verse 9, in 1327.
