Angels 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 AugustineLet those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me.
Saint AugustineMary heard God's word and kept it, and so she is blessed. She kept God's truth in her mind, a nobler thing than carrying his body in her womb.
