6417. Joseph is the son of a fruitful one. That this signifies the spiritual church, in the supreme sense the Lord as to the Divine spiritual, is evident from the representation of Joseph, as being in the supreme sense the Lord as to the Divine spiritual, in the internal sense the spiritual kingdom and the good of faith, and in the external sense fruitfulness and multiplication (see n. 3969, 3971); and because “Joseph” denotes the fruitfulness of good and the multiplication of truth, he is called the “son of a fruitful one.” By “Joseph” is here described the Lord’s spiritual kingdom, and above by “Judah” His celestial kingdom; for there are two kingdoms which constitute heaven, the celestial and the spiritual. The celestial kingdom constitutes the inmost or third heaven; the spiritual kingdom, the middle or second heaven. To the spiritual kingdom the Lord appears as a moon; but to the celestial kingdom as a sun (n. 1053, 1521, 1529-1531, 4060). It is said that by Joseph in the supreme sense is represented the Lord as to the Divine spiritual, but the case is this. The Lord is nothing else than Divine good; that which proceeds from His Divine good and flows into heaven, in His celestial kingdom is called the “Divine celestial,” and in His spiritual kingdom the “Divine spiritual;” thus the Divine celestial and the Divine spiritual are so called relatively to the receptions.
