2 He cried with a mighty voice, saying, “Fallen, fallen is Babylon the great, and has become a habitation of demons, and a prison of every unclean spirit, and a prison of every unclean and hateful bird!
fallen, fallen is Babylon the Great – see also Rev 14:8, this is a continual cry of the Angels, God’s messengers.
a dwelling place of demons – these demons began with Montanism, and Tertullian in 193. These were the demons who were cast down with Satan, to “fling truth to the ground” in Dan 8:12.
a prison of every unclean spirit – the Church became as a man from whom an unclean spirit departed, and seven more wicked spirits entered in (Luke 11:26).
every unclean and hated bird – Dan 4:12, and Matt 13:32, “the birds of the air come and rest” in branches of the corrupted kingdom of heaven.
