21.
There are angels that receive more interiorly the Divine that goes forth from the Lord, and others that receive it less interiorly; the former are called celestial angels, and the latter spiritual angels.
Because of this difference heaven is divided into two kingdoms, one called the Celestial Kingdom, the other the Spiritual Kingdom.# # Heaven as a whole is divided into two kingdoms, a celestial
kingdom and a spiritual kingdom (n. 3887, 4138). The angels of the celestial kingdom receive the Divine of the lord in their voluntary part, thus more interiorly than the spiritual angels, who
receive it in their intellectual part (n. 5113, 6367, 8521, 9936, 9995. 10124).
