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.

681. What celestial and spiritual food is can be seen best of all in the next life. The life of angels and spirits is not maintained by any food like that found in the world but 'by every word that goes out of the mouth of the Lord', as the Lord Himself teaches in Matthew 4:4. The situation is this: The Lord alone is the life of all. From Him comes every single thing that angels and spirits think, say, and do. This applies not only to angels and good spirits but also to evil spirits. The reason the latter speak and do things that are evil is that they receive and corrupt in this way all goods and truths that are the Lord's. For as is the form of the recipient so is the nature of reception and affection. This may be compared to different objects which receive the sun-light. According to their form and according to the arrangement and delimitation of their parts, some convert the rays of light received into unpleasant and hideous colours, while other objects convert them into pleasing and beautiful colours. In such a manner the whole of heaven and the whole of the world of spirits derive their life from everything that goes out of the Lord's mouth, and from this each individual has his life. Indeed this applies not only to heaven and the world of spirits but also to the whole human race. I realize that people are not going to believe it, but I can positively declare from years of uninterrupted personal experience that this is utterly true. Evil spirits in the world of spirits however refuse to believe that it is so, and consequently they have been shown it convincingly time and again until they have grudgingly confessed it to be true. If angels, spirits, and men were deprived of this food they would instantly breathe their last.
