Selection from Arcana Coelestia ~ Emanuel Swedenborg
Unless Something Divine were Concealed Therein
• with the angels through appearances of truth of a higher degree
• with men through appearances of truth of a lower degree
consequently through the Word, in the internal and external senses of which are contained these appearances.
For truths Divine themselves are such that they can never be comprehended by any angel, still less by any man, because they surpass every faculty of their understanding. Yet in order that there may be conjunction of the Lord with them, truths Divine flow in with them in appearances; and when truths Divine are with them in such appearances, they can be both received and acknowledged. This is effected by adaptation to the comprehension of each person; and therefore appearances, that is, truths angelic and human, are of three degrees.
