Necessary angels

“Not only Saint Augustine of Hippo, but also Blessed John Henry Newman, mentioned angels as matters of fact, and in both cases I gather were in touch with them. I do not mean this in some Jungian, mythopoiec way, wherein universally good things are acknowledged, but as abstractions. I mean this in a “touch the earth,” very literal way, as live entities with names and personal characteristics, no two interchangeable.”
