250. XIV. OF EXTERNAL CAUSES OF COLD THE FIFTH IS, INEQUALITY OF EXTERNAL RANK AND CONDITION. There are several inequalities of rank and condition, which while parties are living together put an end to the conjugial love which commenced before marriage; but they may all be referred to inequalities as to age, station, and wealth. That unequal ages induce cold in marriage, as in the case of a lad with an old woman, and of a young girl with a decrepit old man, needs no proof. That inequality of station has a similar effect, as in the marriage of a prince with a servant maid, or of an illustrious matron with a servant man, is also acknowledged without further proof. That the case is the same in regard to wealth, unless a similitude of minds and manners, and an application of one party to the inclinations and native desires of the other, consociate them, is evident. But in all such cases, the compliance of one party on account of the pre-eminence of station and condition of the other, effects only a servile and frigid conjunction; for the conjugial principle is not of the spirit and heart, but only nominal and of the countenance; in consequence of which the inferior party is given to boasting, and the superior blushes with shame. But in the heavens there is no inequality of age, station, or wealth; in regard to age, all there are in the flower of their youth, and continue so into eternity; in regard to station, they all respect others according to the uses which they perform. The more eminent in condition respect inferiors as brethren, neither do they prefer station to the excellence of use, but the excellence of use to station; also when maidens are given in marriage, they do not know from what ancestors they are descended; for no one in heaven knows his earthly father, but the Lord is the Father of all. The case is the same in regard to wealth, which in heaven is the faculty of growing wise, according to which a sufficiency of wealth is given. How marriages are there entered into, may be seen above, n. 229. 251. XV. THERE ARE ALSO CAUSES OF SEPARATION. There are separations from the bed and also from the house. There are several causes of such separations; but we are here treating of legitimate causes. As the causes of separation coincide with the causes of concubinage, which are treated of in the latter part of this work in their own chapter, the reader is referred thereto that he may see the causes in their order. The legitimate causes of separation are the following.
