In speaking of the devil I mean something, though not precisely, like this: Experiences of evil and pressure toward evil that become disturbingly present in our lived experience. We all have these experiences with evil from time to time, and in those moments there’s no doubt that the devil is real. And are angels heavenly energies of grace that are generally non-material (as we understand materiality) but can at times assume a material presence? This seems to be what C.S. Lewis thought and I tend to agree.
