Wicked sons do not have the Holy Ghost in the same way as do beloved sons, and yet they do have Baptism. So, too, heretics do not have the Church as Catholics have, even though they have Baptism.
We must be on our guard against giving interpretations which are hazardous or opposed to science, and so exposing the word of God to the ridicule of unbelievers.
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.
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.
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.
He who does little, but in a state to which God calls him, does more than he who labors much, but in a state which he has thoughtlessly chosen: a cripple limping in the right way is better than a racer out of it.
Temperance is love surrendering itself wholly to Him who is its object; courage is love bearing all things gladly for the sake of Him who is its object; justice is love serving only Him who is its object, and therefore rightly ruling; prudence is love making wise distinction between what hinders and what helps itself.
Fasting cleanses the soul, raises the mind, subjects one’s flesh to the spirit, renders the heart contrite and humble, scatters the clouds of concupiscence, quenches the fire of lust, and kindles the true light of chastity.
Don't hold yourselves cheap, seeing that the creator of all things and of you estimates your value so high, so dear, that he pours out for you every day the most precious blood of his only-begotten Son.
