"Commingled are they with that caitiff choir Of Angels"

(Canto 3, lines 37-38)

The so-called "neutral" angels. They are not really canonical and more like a part of popular belief, however in Revelation 3:15-16 it is said about the "angel of the church of the Laodiceans": "I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth."
