345. X. THAT POLYGAMY IS LASCIVIOUSNESS is because its love is divided among many and, being a love belonging to the external or natural man, is love of the sex and so is not conjugial love, which alone is chaste. That polygamous love is divided among many is well known; and divided love is not conjugial love, for the latter cannot be separated from the one of the sex. Hence a divided love is lascivious, and polygamy is lasciviousness. That polygamous love is love of the sex is because it differs therefrom only in being limited to the number which the polygamist can take, and in being held to certain laws laid down for the public good; also, in that it allows the addition of concubines to wives. Thus, being love of the sex, it is a love of lasciviousness.  That polygamous love is a love belonging to the external or natural man is because it is inscribed on that man; and whatever the natural man does of himself is evil, nor is he led away from this evil except by elevation into the internal spiritual man, which is effected by the Lord alone. As regards the sex, the evil which is within the natural man is whoredom; and because this is destructive of society, therefore, in place of whoredom, its similitude was introduced which is called polygamy. All the evil into which a man is born from his parents is implanted in his natural man, but none in his spiritual man, for into this he is born from the Lord. From the reasons hitherto adduced, and from many others, it can be seen clearly that polygamy is lasciviousness.
