This conjunction or this marriage was thus established from creation. The man was created to be an understanding of truth, and the woman to be an affection for good; and thus the man to be a truth, and the woman to be a good. When understanding of truth which is in the man makes one with the affection for good which is in the woman, there is a conjunction of the two minds into one. This conjunction is the spiritual marriage from which marriage love descends. For when two minds are so conjoined as to be one mind there is love between them; and when this love, which is the love of spiritual marriage, descends into the body it becomes the love of natural marriage. That this is so anyone can clearly perceive if he will. A married pair who interiorly or in respect to their minds love each other mutually and reciprocally also love each other mutually and reciprocally in respect to their bodies. It is well known that all love descends into the body from an affection of the mind, and that apart from such an origin no love exists. Since then the origin of marriage love is the marriage of good and truth, which marriage in its essence is heaven, it is clear that the origin of the love of adultery is a marriage of evil and falsity, which in its essence is hell. Heaven is a marriage because all who are in the heavens are in a marriage of good and truth; and hell is adultery because all who are in the hells are in a marriage of evil and falsity. From this it follows that marriage and adultery are as opposite as heaven and hell are. (A.E., n. 983.) Man was so created as to be spiritual and celestial love, and thus an image and likeness of God. Spiritual love, which is a love for truth, is an image of God; and celestial love, which is a love for good, is a likeness of God. All angels in the third heaven are likenesses of God; and all angels in the second heaven are images of God. Man can become the love which is an image or likeness of God only by a marriage of good and truth; for good and truth inmostly love one another, and ardently long to be united that they may be one; and for the reason that Divine good and Divine truth go forth from the Lord united, therefore they must be united in an angel of heaven and in a man of the church. This union is by no means possible except by a marriage of two minds into one, since, as has been said before, man was created to be an understanding of truth, and thus a truth, and woman was created to be an affection for good, and thus a good; therefore in them a conjunction of good and truth is possible. For marriage love which descends from that conjunction is the veriest medium by which man (homo) becomes the love that is an image or likeness of God. For the married pair who are in conjugal love from the Lord love one another mutually and reciprocally from the heart, thus from inmosts; and therefore although apparently two they are actually one, two in respect to their bodies, but one in respect to life.
