3129. And Rebekah had a brother. That this signifies the affection of good in the natural man, is evident from the signification of a “brother” and a “sister” in the Word, namely, that a “brother” is the affection of good, and a “sister” is the affection of truth (see n. 367, 2360, 2508, 2524); for in the natural man, as in the rational, there are relationships by both blood and marriage of all the things therein (see n. 2556, 2739). And it also is from this that the mind, both the rational and the natural, is called a “house” (or family), where parents, brothers, sisters, kinsmen, and other relatives exist in order.

2739. From the marriage of good and truth in the heavens descend all loves, which are such as the love of parents toward their children, the love of brothers for one another, and the love for relatives, and so on, according to their degrees in their order. According to these loves, which are solely from good and truth, that is, from love to the Lord and faith in Him, are formed all the heavenly societies; which are so joined together by the Lord as to represent one man, and therefore heaven is also called the Grand Man. There are unutterable varieties, all of which take their origin and are derived from the union of good and truth from the Lord, which union is the heavenly marriage. Hence it is that the origin of all consanguinities and relationships on earth is derived from marriages, and that loves were derived in like manner according to their degrees mutually among themselves; but as there is no conjugial love at this day, consanguinities and relationships are indeed reckoned from marriage, but there are no consanguinities and relationships of love. In the Most Ancient Church the derivations of love were of this nature, and therefore they dwell together in the heavens distinguished as it were into nations, families, and houses, all of which acknowledge the Lord as their only Parent.
