457. (12) For the conjugial union of one man with one wife is the precious jewel of human life and the repository of Christian religion. These two points are ones we have already demonstrated universally and singly in the entire preceding part on conjugial love and the delights of its wisdom. Conjugial love is the precious jewel of human life because the character of a person's life is such as the character of that love in him, that love forming the inmost element of his life. For it is the life of wisdom dwelling together with its love, and of love dwelling together with its wisdom, and thus it is the life of the delights of both. In a word, a person is a living soul as a result of that love. That is why we call the conjugial union of one man with one wife the precious jewel of human life.  This conclusion is supported by observations made above: that truly conjugial friendship, trust and potency are possible with only one wife, because only then is there a union of minds (nos. 333, 334); that in and from that union spring the celestial blessings, spiritual felicities and natural delights which from the beginning have been provided for people who are in a state of truly conjugial love (no. 335); that this love is the fundamental love of all celestial, spiritual, and consequently natural loves (nos. 65-67); and that into this love have been gathered all joys and all delights, from the first to the last of them (nos. 68, 69). Moreover, in Delights of Wisdom Relating to Conjugial Love, which forms Part One of this work, it was fully shown that regarded in its origin, this love is the interplay of wisdom and love.
