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.
Isaiah 56:4-5
4
For thus says Yahweh, "To the eunuchs who keep my Sabbaths, and choose the things that please me, and hold fast my covenant:
5
to them I will give in my house and within my walls a memorial and a name better than of sons and of daughters; I will give them an everlasting name, that shall not be cut off.
