Let your old age be childlike, and your childhood like old age; that is, so that neither may your wisdom be with pride, nor your humility without wisdom.
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.
What then, is correctness of speech but the maintenance of the practice of others, as established by the authority of ancient speakers? But the weaker men are, the more they are troubled by such matters. Their weakness stems from a desire to appear learned, not with a knowledge of things, by which we are edified, but with a knowledge of signs, by which it is difficult not to be puffed up in some way; even a knowledge of things often makes people boastful, unless their necks are held down by the Lord's yoke.
Some people, in order to discover God, read books. But there is a great book: the very appearance of created things. Look above you! Look below you! Read it. God, whom you want to discover, never wrote that book with ink. Instead, He set before your eyes the things that He had made. Can you ask for a louder voice than that?
God suffers not the pain of repentance, nor is He deceived in any matter, so that He would wish to correct that wherein He has erred. But as when a man repents of anything, he wishes to change what he has done; thus where you hear that God repents, look for an actual change. God does it differently from you, although He calls it by the name of repentance; for thou dost it, because you had erred; while He does it, because He avenges, or frees.
The mere change of custom, even though it may be of advantage in some respects, unsettles men by reason of the novelty: therefore, if it brings no advantage, it does much harm by unprofitably disturbing the Church.
Although among heretics and schismatics there is the same Baptism, nevertheless, the remission of sins is not operative among them because of the very rottenness of discord and wickedness of dissension ... Baptism was in them, but it did not profit them outside the Church ... Outside the Church, Baptism works death because of discord.
For I did not know that the soul needs to be enlightened by light from outside itself, so that it can participate in truth, because it is not itself the nature of truth.
Wonderful is the depth of thy words, whose surface is before us, gently leading on the little ones: and yet a wonderful deepness, O my God, a wonderful deepness. It is awe to look into it; even an awfulness of honour, and a trembling of love.
Furthermore, what profit was it to me that I, rascally slave of selfish ambitions that I was, read and understood by myself as many books as I could get concerning the so-called liberal arts?...I had turned my back to the light and my face to the things it illuminated, and so no light played upon my own face, or on the eyes that perceived them.
