Devils are depicted with bats' wings and good angels with birds' wings, not because anyone holds that moral deterioration would be likely to turn feathers into membrane, but because most men like birds better than bats.
C. S. LewisOne of our great allies at present is the Church itself. Do not misunderstand me. I do not mean the Church as we see her spread out through all time and space and rooted in eternity, terrible as an army with banners. That, I confess, is a spectacle which makes our boldest tempters uneasy. But fortunately it is quite invisible to these humans.
