Hence it is, that in the world it is said, "To the pure all things are pure, and to the defiled all things are defiled." 141. II. THE CHASTE PRINCIPLE IS PREDICATED ONLY OF MONOGAMICAL MARRIAGES, OR OF THE MARRIAGE OF ONE MAN WITH ONE WIFE. The reason of this is, because with them conjugial love does not reside in the natural man, but enters into the spiritual man, and successively opens to itself a way to the essential spiritual marriage, or the marriage of good and truth, which is its origin, and conjoins itself therewith; for that love enters according to the increase of wisdom, which is according to the implantation of the church from the Lord, as has been abundantly shewn above. This cannot be effected with polygamists; for they divide conjugial love; and this love when divided, is not unlike the love of the sex, which in itself is natural; but on this subject something worthy of attention may be seen in the section on POLYGAMY. 142. III. THE CHRISTIAN CONJUGIAL PRINCIPLE ALONE IS CHASTE. This is, because love truly conjugial keeps pace with the state of the church in man (_homo_), and because the state of the church is from the Lord, as has been shewn in the foregoing section, n. 130, 131, and elsewhere; also because the church in its genuine truths is in the Word, and the Lord is there present in those truths. From these considerations it follows, that the chaste conjugial principle exists nowhere but in the Christian world, and still that there is a possibility of its existing elsewhere. By the Christian conjugial principle we mean the marriage of one man with one wife. That this conjugial principle is capable of being ingrafted into Christians, and of being transplanted hereditarily into the offspring from parents who are principled in love truly conjugial, and that hence both the faculty and the inclination to grow wise in the things of the church and of heaven may become connate, will be seen in its proper place. Christians, if they marry more wives than one, commit not only natural but also spiritual adultery: this will be shewn in the section on POLYGAMY.
