Selection from Heaven and Hell ~ Emanuel Swedenborg
What has been said of heaven may be said also of the church, for the church is the Lord's heaven on earth. There are also many churches, each one of which is called a church, and so far as the good of love and faith reigns therein is a church. Here, too, the Lord out of various parts forms a unity, that is, one church out of many churches.And the like may be said of the man of the church in particular that is said of the church in general, namely, that the church is within man and not outside of him; and that every man is a church in whom the Lord is present in the good of love and of faith.
Again, the same may be said of a man that has the church in him as of an angel that has heaven in him, namely, that he is a church in the smallest form, as an angel is a heaven in the smallest form; and furthermore that a man that has the church in him, equally with an angel, is a heaven. For man was created that he might come into heaven and become an angel; consequently he that has good from the Lord is a man-angel.
What man has in common with an angel and what he has in contrast with angels may be mentioned. It is granted to man, equally with the angel, to have his interiors conformed to the image of heaven, and to become, so far as he is in the good of love and faith, an image of heaven. But it is granted to man and not to angels to have his exteriors conform to the image of the world; and so far as he is in good to have the world in him subordinated to heaven and made to serve heaven. And then the Lord is present in him both in the world and in heaven just as if he were in his heaven. For the Lord is in His Divine order in both worlds, since God is order.
