Because of their understanding of spiritual marriage, the people of the Most Ancient church perceived 'male and female' as two faculties in the spiritual self: 'male' refers to the understanding and 'female,' to the will. When these faculties act as one, they called it 'marriage.'

In Revelation 19:11, this signifies revelation from the Lord respecting the internal sense of the Word, which is seen only by people whose spiritual minds are opened; i.e., people who love the Lord and have genuine faith in Him. (Arcana Coelestia 2760[2])
