From this it is now evident that true marriage love is from the Lord alone, and exists in those who are in the conjunction of good and truth from the Lord. As this conjunction is reciprocal it is said by the Lord that
They are in Him, and He in them (John xiv. 20).
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.
This may be compared to the eyes, which are two as organs but one in respect to the sight; also to the ears, which are two as organs but one in respect to hearing; so, too, the arms and the feet are two as members but one in respect to use, the arms one in respect to action, and the feet one in respect to walking. So with the other pairs with man. All these have reference to good and truth, the organ or member on the right to good, and that on the left to truth. It is the same with a husband and wife between whom there is a true marriage love; they are two in respect to their bodies but one in respect to life; consequently in heaven the married pair are not called two angels but one. All this makes clear that through marriage man becomes a form of love, and thus a form of heaven, which is an image and likeness of God.
Man is born into a love of evil and falsity, which love is the love of adultery; and this love cannot be turned about and changed into spiritual love, which is an image of God, and still less into celestial love, which is a likeness of God, except by a marriage of good and truth from the Lord, and not fully except by a marriage of two minds and two bodies. From this it is clear why marriages are heavenly and adulteries infernal; for marriage is an image of heaven, and true marriage love is an image of the Lord, while adultery is an image of hell, and love of adultery is an image of the devil. Moreover, marriage love appears in the spiritual world in form like an angel, and love of adultery in form like a devil. Reader, treasure this up within you, and after death, when you are living as a spirit-man, inquire whether this is true, and you will see. (A.E., n. 984.)
How profane and thus how much to be detested adulteries are can be seen from the holiness of marriages. All things in the human body, from the head to the sole of the feet, both interior and exterior, correspond to the heavens, and in consequence man is a heaven in its least form, and also angels and spirits are in form perfectly human, for they are forms of heaven. All the members devoted to generation in both sexes, especially the womb, correspond to societies of the third or inmost heaven, and for the reason that true marriage love is derived from the Lord's love for the church, and from the love of good and truth which is the love of the angels of the third heaven; therefore marriage love, which descends therefrom as the love of that heaven, is innocence, which is the very being (esse) of every good in the heavens. And for this reason embryos in the womb are in a state of peace, and when they have been born as infants are in a state of innocence; so, too, is the mother in relation to them.
As this is the correspondence of the genital organs in the two sexes, it is evident that by creation they are holy, and therefore they are devoted solely to chaste and pure marriage love, and are not to be profaned by the unchaste and impure love of adultery, by which man converts the heaven in himself into hell; for as the love of marriage corresponds to the love of the highest heaven, which is love to the Lord from the Lord, so the love of adultery corresponds to the love of the lowest hell.
