6. What is meant by "Jerusalem" in the spiritual sense of the Word, shall also be briefly stated. "Jerusalem" means the church itself as to doctrine, because there in the land of Canaan, and in no other place, were the temple, the altar, the sacrifices, and thus Divine worship itself. On this account, also, three festivals were celebrated there every year, to which every male throughout the whole land was commanded to go. This, then, is the reason why "Jerusalem," in the spiritual sense, signifies the church as to worship, or, what is the same, as to doctrine; for worship is prescribed in doctrine, and is performed according to it. The reason why it is said, "The holy city, New Jerusalem, descending from God out of heaven," is because, in the spiritual sense of the Word, "a city" [civitas] and "a town" [urbs], signify doctrine, and "the holy city" the doctrine of Divine truth, since Divine truth is what is called "holy" in the Word. It is called "the New Jerusalem" for the same reason that "the earth" is called "new"; because, as was observed above, "the earth" signifies the church, and "Jerusalem," the church as to doctrine; which is said "to descend from God out of heaven," because all Divine truth, whence doctrine is derived, descends out of heaven from the Lord. That "Jerusalem" does not mean a city, although it was seen as a city, manifestly appears from its being said that:

Its height was, as its length and breadth, twelve thousand stadia (Rev. 21:16).

And that the measure of its wall, which was a hundred forty-four cubits, was the measure of a man, that is, of the angel (Rev. 21:17).

Also from its being said that:

It was prepared as a Bride adorned for her Husband (verse 2).

And afterwards the angel said:

Come, I will show thee the Bride, the Lamb's Wife: and he showed me that great city, the holy Jerusalem (verses 9, 10).

The church is called in the Word "the Bride" and "the Wife" of the Lord; she is called "the Bride" before conjunction, and "the Wife" after conjunction. As may be seen in the Arcana Coelestia (n. 3103, 3105, 3164-3165, 3207, 7022, 9182).

7022. 'And Moses took his wife' means the good linked to [the law from God]. This is clear from the representation of 'Moses' as the Lord in respect of the law or truth from God, dealt with already; and from the meaning of 'wife' as the good linked to it, dealt with in 4510, 4823. In the internal sense, and also in the highest sense in which the Lord is the subject, 'the wife' who was married to Moses represents the good that had been joined to truth, the reason for this being that every single thing in the spiritual world and in the natural world has the likeness of a marriage within it. The likeness of a marriage exists wherever there is that which is active and that which is passive; and both must be present with each other wherever anything comes into being. Unless they are joined together nothing can possibly be produced. One reason why the likeness of a marriage is present in all things is that all things have a connection with goodness and truth and so with the heavenly marriage, which is a marriage of goodness and truth; and the heavenly marriage has a connection with the Divine marriage, which is a marriage of Divine Good and Divine Truth. And another reason is, as has been stated, that nothing can be produced or brought into being unless there is that which is active and that which is passive, and so unless the likeness of a marriage exists. From all this it is plainly evident that the truth of faith devoid of the good of charity cannot produce anything, and neither can the good of charity devoid of the truth of faith. The two must be joined together to bear fruit and to establish the life of heaven in a person. Regarding the likeness of a marriage present in every single thing, see 1432, 2177, 2516, 5194. And since each detail of the Word has the marriage of goodness and truth within it, 683, 793, 801, 2516, 2712, 4138 (end), 5138, 6343, each detail of the Word has heaven within it, for heaven constitutes that actual marriage. And since each detail of the Word has heaven within it, each detail has the Lord within it, because the Lord is the All in all of heaven. All this shows how it comes about that 'the wife of Moses' represents the good that had been joined to truth, even in the highest sense in which the Lord is the subject, in the same way as Sarah the wife of Abraham represents such good, dealt with in 2063, 2065, 2172, 2173, 2198, and also Rebekah the wife of Isaac, in 3012, 3013, 3077.
