Apocalypse Explained #184
184. And the seven stars, signifies from whom are all the knowledges of truth and good. This is evident from the signification of "seven," as being what is full and all things (See above, n. 20, 24), also from the signification of "stars" as being the knowledges of truth and good (See also above, n. 72). It is said to the angel of this church, "These things saith He that hath the seven spirits of God, and the seven stars," because those within the church who are living a moral but not a spiritual life, because they have little regard for the knowledges of spiritual things and thence for intelligence and wisdom, are here treated of; for "the seven spirits of God" signify all the truths of heaven and of the church, and "the seven stars" the knowledges of truth and good; and through these two come all intelligence and wisdom. To the angel of each church is premised something respecting the Lord, which indicates what is treated of (See above, n. 113).
Heaven and Hell #140
140. Since the Lord as the sun is divine love, and divine love is the essential divine good, the divine that emanates from him - his divine nature in heaven - is called divine truth for the sake of clarity, even though it is divine good united to divine truth. This divine truth is what is called "the holy" that emanates from him.
