Emanuel Swedenborg

“ And as all good pertains to love (for good to any one is what he loves) the good also of the other kingdom is called celestial, and the good of the other spiritual. Evidently, then, the two kingdoms are distinguished from each other in the same way as good of love to the Lord is distinguished from good of love towards the neighbor. [5] And as the good of love to the Lord is an interior good, and that love is interior love, so the celestial angels are interior angels, and are called higher angels. ”

“ Moreover, every truth is turned into good and implanted in love as soon as it enters into the will; but so long as truth remains in the memory and in the thought therefrom it does not become good, nor does it live, nor is it appropriated to man, since man is a man from his will and understanding therefrom, and not from his understanding separated from his will. [9]
27. Because of this difference between the angels of the celestial kingdom and the angels of the spiritual kingdom they are not together, and have no interaction with each other. ”

“ It has been said that these angels have wisdom and glory above others for the reason that they have received and continue to receive Divine truths at once in their life. For as soon as they hear Divine truths, they will and do them, instead of storing them up in the memory and afterwards considering whether they are true. They know at once by influx from the Lord whether the truth they hear is true; for the Lord flows directly into man's willing, but mediately through his willing into his thinking. ”
