The love of marriage is so holy and heavenly because it has its beginning in the inmosts of man from the Lord Himself, and it descends according to order to the outmosts of the body, and thus fills the whole man with heavenly love and brings him into a form of the Divine love, which is the form of heaven, and is an image of the Lord. But the love of adultery has its beginning in the outmosts of man from an impure lascivious fire there, and thus, contrary to order, penetrates toward the interiors, always into the things that are man's own, which are nothing but evil, and brings these into a form of hell, which is an image of the devil. Therefore a man who loves adultery and turns away from marriage is in form a devil.
As the organs of generation in the two sexes correspond to the societies of the third heaven, and the love of a married pair corresponds to the love of good and truth, so those organs and that love correspond to the Word. The reason is that the Word is Divine truth united to Divine good going forth from the Lord; and this is why the Lord is called "the Word," also why in every particular of the Word there is a marriage of good and truth, or a heavenly marriage. That there is such a correspondence is a mystery not yet known in the world, but it has been made evident and proved to me by much experience.
From this also it is clear how holy and heavenly marriages are in themselves, and how profane and diabolical adulteries are. And for this reason adulterers make no account of Divine truths and thus of the Word, and if they were to speak from the heart they would even blaspheme the holy things that are in the Word. This they do when they have become spirits after death, for every spirit is compelled to speak from the heart, that his interior thoughts may be revealed. (A.E., n. 985.)
As all the delights that man has in the natural world are turned into correspondent delights in the spiritual world, so are the delights of the love of marriage and the delights of the love of adultery. The love of marriage is represented in the spiritual world as a virgin, whose beauty is such as to inspire the beholder with the charms of life; while the love of adultery is represented in the spiritual world by an old woman, whose deformity is such as to inspire in the beholder a coldness and death to every charm of life. Therefore in the heavens the angels are beautiful according to the quality of marriage love in them, and in the hells the spirits are deformed according to the quality of the love of adultery in them. In a word, the angels of heaven have life in their faces, in the movements of the body, and in their speech, in the measure of their marriage love, while the spirits of hell have death in their faces in the measure of their love of adultery.
In the spiritual world the delights of marriage love are represented to the sense by odors from fruits and flowers of various kinds, while the delights of the love of adultery are there represented to the sense by the stenches from excrements and putridities of various kinds. Moreover, the delights of the love of adultery are actually turned into such things, since all things pertaining to adultery are spiritual filth. Therefore from the brothels in the hells stenches pour forth that excite vomiting. (A.E., n. 986.)
How holy in themselves, that is, from creation, marriages are can be seen from the fact that they are the nurseries of the human race; and as the angelic heaven is from the human race they are also the nurseries of heaven; consequently by marriages not only the earths but also the heavens are filled with inhabitants; and as the end of the entire creation is the human race, and thus heaven, where the Divine itself may dwell as in its own and as it were in itself, and as the procreation of mankind according to Divine order is accomplished through marriages, it is clear how holy marriages are in themselves, that is, from creation, and thus how holy they should be esteemed. It is true that the earth might be filled with inhabitants by fornications and adulteries as well as by marriages, but not heaven; and for the reason that hell is from adulteries but heaven from marriages.
Hell is from adulteries because adultery is from the marriage of evil and falsity, from which hell in the whole complex is called adultery; while heaven is from marriages because marriage is from the marriage of good and truth, from which heaven in its whole complex is called a marriage. That is called adultery where its love, which is called a love of adultery, reigns, whether it be within wedlock or apart from it, and that is called marriage where its love, which is called marriage love, reigns.
When procreations of the human race are effected by marriages in which the holy love of good and truth from the Lord reigns, then it is on earth as it is in the heavens, and the Lord's kingdom on earth corresponds to the Lord's kingdom in the heavens. For the heavens consist of societies arranged according to all the varieties of celestial and spiritual affections, from which arrangement the form of heaven springs, and this pre-eminently surpasses all other forms in the universe. There would be a like form on the earth if the procreations there were effected by marriages in which a true marriage love reigned; for then, however many families might descend in succession from one head of a family, there would spring forth as many images of the societies of heaven in a like variety.
Families would then be like fruit-bearing trees of various kinds, forming as many different gardens, each containing its own kind of fruit, and these gardens taken together would present the form of a heavenly paradise. This is said in the way of comparison, because "trees" signify men of the church, "gardens" intelligence, "fruits" goods of life, and "paradise" heaven. I have been told from heaven that with the most ancient people, from whom the first church on this globe was established, which was called by ancient writers the golden age, there was such a correspondence between families on the earth and societies in the heavens, because love to the Lord, mutual love, innocence, peace, wisdom, and chastity in marriages then prevailed; and it was also told me from heaven that they were then inwardly horrified at adulteries, as at the abominable things in hell. (A.E., n. 987.)
That heaven is from marriages and hell from adulteries has been shown above. What this means shall now be told. The hereditary evils into which man is born are not from Adam's having eaten of the tree of knowledge, but from the adulteration of good and the falsification of truth by parents, thus from the marriage of evil and falsity, from which a love of adultery springs. The ruling love of parents by means of a germ from it passes over into the offspring and is transcribed upon it and becomes its nature. If the love of the parents is a love of adultery it is also a love of evil for falsity and of falsity for evil. From this source man has all evil, and from evil he has hell. All this makes clear that it is from adulteries that man has hell, until he is reformed by the Lord by means of truths and a life according to them. And no one can be reformed unless he shuns adulteries as infernal and loves marriages as heavenly. In this and in no other way is hereditary evil broken and rendered milder in the offspring.
