For they derive a different disposition from a different kind of life implanted by parents through the ages, so that they have an altogether different life. Consequently they have a different nature which is consociated with celestial things, as was noted [n. 564] at the representation of the rainbow among the angels of their interior heaven; and because their nature is then consociated with celestial things, representatively as the colors of the rainbow, and the nature of each, being from a different root, is diverse, the interior angels cannot be consociated.
