For when God said, "Let there be light, and there was light," if we are justified in understanding in this light the creation of the angels, then certainly they were created partakers of the eternal light which is the unchangeable Wisdom of God, by which all things were made, and whom we call the only-begotten Son of God.
Saint AugustineWe cannot pass our guardian angel's bounds, resigned or sullen, he will hear our sighs.
Saint AugustineIn all your movements, let nothing be evident that would offend the eyes of another.
