10. The twenty-first chapter in the book of Revelation describes the holy Jerusalem in this way, that it had in it a light “like a most precious stone, like a jasper stone, bright as crystal;” that it had “a great and high wall, and twelve gates, and over the gates twelve angels, with names written on them...of the twelve tribes of the children of Israel;” that it had a wall of “a hundred and forty-four cubits, the measure of a man, that is, of an angel;” that the construction of its wall was of jasper, and its foundations of all kinds of precious stones — jasper, sapphire, chalcedony, emerald, sardonyx, sardius, chrysolite, beryl, topaz, chrysoprase, jacinth, and amethyst; that “the twelve gates were twelve pearls;” that the city was “pure gold, like transparent glass;” and that it was square, “its length, breadth, and height...equal, ” measuring “twelve thousand furlongs.” And so on.

All of these particulars must be understood spiritually, as can be seen from the fact that the holy Jerusalem symbolizes a new church to be established by the Lord, as we showed in The Doctrine of the New Jerusalem Regarding the Lord 62-65. And because Jerusalem in this description symbolizes a church, it follows that everything said about it as a city — about its gates, its wall, the foundations of the wall, and about their measurements — contains a spiritual meaning. For matters having to do with the church are spiritual.

[2] We have explained the symbolic meanings of each of these particulars in The New Jerusalem and its Heavenly Doctrine (London, 1758), no. 1. We therefore forgo any further explanation of them here. It is enough for it to be known from that book that there is a spiritual meaning present in each particular of the city’s description, like a soul in its body. Also, that apart from that meaning, nothing relating to the church would be understood in the depictions there, as that the city was of pure gold, with its gates of pearls, its wall of jasper, and the foundations of its wall of precious stones; that the wall was of a hundred and forty-four cubits, the measure of a man, that is, of an angel; that the city itself was twelve thousand furlongs long, wide, and high; and so on.

Someone who has a knowledge of correspondences and knows from it the spiritual sense, understands the meanings of these things — as that the wall and its foundations symbolize doctrine drawn from the Word’s literal sense, and that the numbers 12,144, and 12,000 have similar symbolic meanings, namely all the truths and goods of the church in their entirety.

54. Doctrine not only makes the Word understandable, but also to shine, so to speak, and that is because the Word is not understood apart from doctrine and is like a lampstand without any light, as we showed above. Doctrine is what makes the Word understandable, therefore, so as to be like a lampstand with its lamp lit. A person then sees much more than he saw before, and also understands what he had not understood before. Dark and conflicting passages he either does not see and passes on by, or sees and explains them so as to be in harmony with the doctrine.

The Word’s being viewed in the light of doctrine, and moreover explained in accordance with it, is something experience in the Christian world attests. For the Protestant Reformed all see the Word in the light of their doctrine and explain the Word in accordance with it. Roman Catholics likewise see the Word in the light of their doctrine and explain it in accordance with that doctrine. Indeed, Jews do the same. Consequently falsities are seen in the light of a false doctrine, and truths in the light of a true doctrine.

It is apparent, therefore, that a true doctrine is like a lamp shining in darkness, and like a signpost pointing the way.

Doctrine, however, must not only be drawn from the Word’s literal sense, but it must also be verified by it. For if not verified by it, doctrinal truth has the appearance of having only man’s intelligence in it, and not the Lord’s Divine wisdom, and in that case doctrine would be like a house in the air and not on the ground, thus one without its foundation.
