I had a discussion with a brother recently. He believes that there is a difference between fallen angels, unclean spirits and demons. I could show him easily from the Gospels that demons and unclean spirits are the same. But he still insists that fallen angels are not demons. I asked him to show me that in the Bible. He asked me to prove the opposite but I couldn´t either. I belive that Satan fell and some angels with him. Those angels are now called fallen angels or unclean spirits or demons. Every help is appreciated.
