Arcana Coelestia #61
61. Everything that has to do with cognitions of faith is called spiritual, and everything that has to do with love to the Lord and towards the neighbour is called celestial. The former belong to man's understanding, the latter to his will.

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
