2435. That I will not overthrow the city of which thou hast spoken. That this signifies that so he would not perish, namely, the man with whom there is truth within which there is good, is evident from the signification of a “city,” as being truth (see n. 402, 2268, 2428). It has been disputed from the most ancient times which is the firstborn of the church, charity or faith; for the reason that man is regenerated and becomes a church by means of the truths of faith. But they who have set faith foremost and made it the firstborn, have all fallen into heresies and falsities, and at length have extinguished charity altogether; as we read of Cain, by whom such faith is signified, that at length he killed his brother Abel, by whom is signified charity; and afterwards of Reuben, the firstborn son of Jacob, by whom likewise faith is signified, that he polluted his father’s couch (Genesis 35:22; 49:4), and therefore was held unworthy, and the primogeniture was given to Joseph (Genesis 48:5; 1 Chron. 5:1).

[2] This was the source of all the contentions, and also all the laws, respecting primogeniture that are mentioned in the Word. The cause of there being such a controversy was that it was not known, as even at this day it is not known, that a man has only so much of faith as he has of charity; and that when a man is being regenerated, charity presents itself to faith, or what is the same, good presents itself to truth, and insinuates itself into it and adapts itself to it in every particular, causing faith to be faith; and thus that charity is the very firstborn of the church, although to man it appears otherwise (see also n. 352, 367 t as these things will frequently be treated of hereafter, of the Lord’s Divine mercy we shall say more on the subject as the occasion arises.

367. It is unnecessary to confirm these things by similar passages from the Word, except so far as to prove that charity is the “brother” of faith, and that a “field” signifies whatever is of doctrine. That charity is the “brother” of faith is evident to everyone from the nature or essence of faith. This brotherhood was represented by Esau and Jacob, and was the ground of their dispute about the birthright and the consequent dominion. It was also represented by Pharez and Zarah, the sons of Tamar by Judah (Genesis 38:28-29, 30); and by Ephraim and Manasseh (Genesis 48:13-14); and in both of these, as well as in other similar cases, there is a dispute about the primogeniture and the consequent dominion. For both faith and charity are the offspring of the church. Faith is called a “man” as was Cain, in verse 1 of this chapter, and charity is called a “brother” as in Isaiah 19:2; Jeremiah 13:14 and other places. The union of faith and charity is called “the covenant of brethren” (Amos 1:9). Similar to the signification of Cain and Abel, was that of Jacob and Esau, as just said; in that Jacob also was desirous of supplanting his brother Esau, as is evident also in Hosea:

To visit upon Jacob his ways, according to his doings will He recompense him; he supplanted his brother in the womb (Hosea 12:2-3).

But that Esau, or the charity represented by Esau, should nevertheless at length have the dominion, appears from the prophetic prediction of their father Isaac:

By thy sword shalt thou live, and shalt serve thy brother; and it shall come to pass, when thou hast the dominion, that thou shalt break his yoke from off thy neck (Genesis 27:40).Or what is the same, the Church of the Gentiles, or new church, is represented by Esau, and the Jewish Church is represented by Jacob; and this is the reason for its being so often said that the Jews should acknowledge the Gentiles as brethren; and in the Church of the Gentiles, or primitive church, all were called brethren, from charity. Such as hear the Word and do it are likewise called brethren by the Lord (Luke 8:21); those who hear are such as have faith; those who do are such as have charity; but those who hear, or say that they have faith, and do not, or have not charity, are not brethren, for the Lord likens them unto fools (Matthew 7:24, 26).
