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.
Revelation 6:10
10
They cried with a loud voice, saying, "How long, Master, the holy and true, until you judge and avenge our blood on those who dwell on the earth?"
