538. About the Dragon
It is amazing that although the dragon, or the "old serpent," does not cease to persecute believers - so very cunningly that I cannot describe his wiles and poisons - he has nevertheless admitted several times that he knows better than all others that Jesus Christ is the God of the universe, and governs the universe. Moreover, spirits can also speak with him, and I have spoken with him just as with another person, often exposing his tricks in front of him. But I have done this only [through] spirits. Those who are in the heavens do not speak except through spirits.
