“Now the Apostle, under the inspiration of the Holy Spirit, says, "Knowledge inflates: but love edifies." The only correct inerpretation of this saying is that knowledge is valuable when charity informs it. Without charity, knowledge inflates; that is, it exalts man to an arrogance which is nothing but a kind of windy emptiness.”
“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.”
“His knowledge is not like ours, which has three tenses: present, past, and future. God's knowledge has no change or variation.”
“Charity is no substitute for justice withheld.”
“Yet we must say something when those who say the most are saying nothing.”
“After saying all that, what have we said, my God, my life, my holy sweetness? What does anyone who speaks of you really say? Yet woe betide those who fail to speak, while the chatterboxes go on saying nothing.”
“The wisdom of what a person says is in direct proportion to his progress in learning the holy scriptures--and I am not speaking of intensive reading or memorization, but real understanding and careful investigation of their meaning. Some people read them but neglect them; by their reading they profit in knowledge, by their neglect they forfeit understanding.”
