The sky and the earth and the waters and the things that are in them, the fishes, and the birds and the trees are not evil. All these are good; it is evil men who make this evil world.
Saint AugustineAngels are spirits, but it is not because they are spirits that they are angels. They become angels when they are sent. For the name angel refers to their office, not their nature. You ask the name of this nature, it is spirit; you ask its office, it is that of an Angel, which is a messenger.
Saint Augustine
