Apocalypse Explained # 330
330. Out of every tribe and tongue. That this signifies from all those who are in truths as to doctrine and as to life, is clear from the signification of a tribe, as denoting all truths and goods in the aggregate (concerning which see above, n. 39); for those things are signified by the twelve tribes, and hence by every tribe is signified something of truth and good, therefore by out of every tribe is signified from all those who are in any kind of truth and good; and from the signification of tongue as denoting the doctrine of life and faith. That tribes signify all truths and goods in the aggregate, will be shown more fully in its proper article below. Similarly, that tongue signifies the doctrine of life and faith, thus religion. (Those [passages] only shall be adduced here that are shown in the Arcana Coelestia concerning the signification of the tribes, namely, the twelve tribes of Israel represented, and thence signified, all truths and goods in the aggregate, n. 3858, 3926, 4060, 6335; similarly the twelve apostles of the Lord the like, n. 2129, 3354, 3488, 6397. There were twelve, because twelve signifies all, n. 577, 2089, 2129, 2130, 3272, 3858, 3913. Because the twelve tribes represented, and thence signified, all truths and goods in the aggregate, therefore they represented heaven and the church, n. 6337, 6637, 7836, 7891, 7996. The twelve tribes signify various things according to the order in which they are named, and thus also all things of heaven and the church with variety, n. 3862, 3926, 3939, 4603 et seq., 6337, 6640, 10335; therefore, replies could be given and were given by the Urim and Thummim, on which the names of the twelve tribes of Israel were engraven in precious stones, n. 3858, 6335, 6640, 9863, 9865, 9873, 9874, 9905.)
The New Jerusalem and its Heavenly Teachings # 7
7. Turning specifically to the body of teaching that now follows, it too comes from heaven because it comes from the spiritual meaning of the Word, and the spiritual meaning of the Word is the same as the body of teaching that is found in heaven. You see, there is a church in heaven just as there is on earth. That is, the Word is there, there is a body of teaching drawn from the Word, and there are church buildings there with sermons being delivered-all because there are both ecclesiastical and civil institutions there. In brief, the only difference between things in the heavens and things on earth is that everything in heaven is in a more perfect state because all the people there are spiritual, and spiritual realities are far more perfect than earthly ones. On the fact that this is what heaven is like, see my book Heaven and Hell throughout, especially the chapters on forms of government in heaven (§§213-220) and divine worship there (§§221-227).
This shows what it means when it says that a holy city, a New Jerusalem, was seen coming down from God out of heaven.
But I need to turn now to the actual teachings for this new church, which are called "heavenly" because they have been revealed to me from heaven. That is, after all, the reason for this book.
