256. It was said above, that by the seven churches here written to, are not meant seven churches, but all those who belong to the church, and, in the abstract, all things of the church; that this is the case is evident from the consideration, that by seven are signified all, and all things, and that by the names are signified things. That all who belong to the church, or all things of the church, are meant by what is written to those seven churches is also evident from the explanation of those things. For all things of the church have reference to the following four general principles, doctrine, life according to it, faith according to life. These are treated of in what is written to six of the churches - doctrine, to the churches in Ephesus and Smyrna; life according to doctrine, to the churches in Thyatira and Sardis; and faith according to life, to the churches in Philadelphia and Laodicea. And because doctrine cannot be implanted in man's life and become a matter of faith unless he fights against the evils and falsities which he possesses from heredity, therefore that combat is also treated of in what is written to the church in Pergamos; for the subject there treated of is temptations; and temptations are combats against evils and falsities.

(That temptations are treated of in what is written to the church in Pergamos may be seen above, n. 130; that doctrine is the subject treated of in what is written to the churches in Ephesus and Smyrna may be seen above also, n. 93, 95, 112; that a life according to doctrine is treated of in what is written to the churches in Thyatira and Sardis, (n. 150, 182, and that faith according to life is treated of in what is written to the churches of Philadelphia and Laodicea, n. 203 and 227.) Because in what is written to this last church, namely, that in Laodicea, those who are in the doctrine of faith alone are treated of, and also, at the end, the nature of faith originating in charity, to what has already been said, it is here to be added, that love constitutes heaven; and because it does so, it also forms the church. For all the societies of heaven, which are innumerable, are arranged according to the affections of love, and also all within each society; so that it is affection, or love, according to which all things are arranged in the heavens, and not in any case faith alone. Spiritual affection, or love, is charity. It is therefore clear that no one can ever enter heaven unless he is in charity.

566. WHAT HELL FIRE IS AND WHAT THE GNASHING OF TEETH IS.

What eternal fire is, and what the gnashing of teeth is, which are mentioned in the Word in reference to those who are in hell, scarcely any one as yet has known, because the contents of the Word have been thought about only in a material way, and nothing has been known about its spiritual sense. So fire has been understood by some to mean material fire, by others to mean torment in general, by others remorse of conscience, and others have held that it is mentioned merely to excite terror in the wicked. Likewise some have supposed the gnashing of teeth to mean actual gnashing, and some only a horror, such as is excited when such a collision of teeth is heard. But any one who is acquainted with the spiritual meaning of the Word may know what eternal fire is, and what the gnashing of teeth is; for every expression and every meaning of the expressions in the Word contains a spiritual meaning, since the Word in its bosom is spiritual; and what is spiritual can be set before man only in natural forms of expression, because man is in the natural world and thinks from the things of that world. Therefore it shall now be told what is meant by "eternal fire" and "the gnashing of teeth" into which the spirits of evil men enter after death, or which their spirits, then in the spiritual world, endure.
