143. (4) Truly conjugial love is the essence of chastity. The reasons for this are as follows:
1. Conjugial love is from the Lord, and it corresponds to the marriage of the Lord and the church. 2. It descends from the marriage between good and truth. 3. It is spiritual, as the church in a person is spiritual. 4. It is the fundamental love and the head of all celestial and spiritual loves. 5. It is truly the seedbed of the human race and consequently of the angelic heaven. 6. It exists, therefore, also among angels of heaven, and from it are born with them spiritual offspring, which are love and wisdom. 7. The use it serves is thus more excellent than the other uses in creation. It follows from these considerations that, regarded from its origin and in its essence, truly conjugial love is pure and sacred - so pure and sacred that it may be called the essence of purity and sacredness, consequently of chastity. But still, it is not entirely pure in people, not even in angels, as may be seen in no. 146, which follows here under point (6) below.
