143. IV. THAT LOVE TRULY CONJUGIAL IS CHASTITY ITSELF. The reasons are: 1. Because it is from the Lord and corresponds to the marriage of the Lord and the Church. 2. Because it descends from the marriage of good and truth. 3. Because it is spiritual, as is the Church with man. 4. Because it is the fundamental love and the chief of all celestial and spiritual loves. 5. Because it is the lawful seminary of the human race and thence of the angelic heaven. 6. Because for this reason it is also with the angels of heaven, and from it, with them, are born spiritual offspring which are love and wisdom. And 7. Because its use is thus more excellent than all other uses of creation. From this it follows that love truly conjugial, regarded from its origin and in its essence, is pure and holy, so that it may be called purity and holiness itself and consequently chastity itself. That yet, it is not absolutely pure with either men or angels, may be seen in article VI, no. 146, which follows presently.
