Those of you who are over others, pay special attention to your neighbors, particularly to those who have not been entrusted to your care. You do not know what good may lie hidden even in those you see doing something wrong. Let each of you, then, strive to be great in virtue, but nonetheless let him know that he is not so in some degree. Otherwise he may proudly attribute his greatness to himself and lose whatever good he has; he might even be rejected because of his sin of pride. - "Forty Gospel Homilies 4"
Who is the greatest subverter of the people of God—he who, relying on the power of free choice, despises the help of the Creator and is satisfied with following his own will, or he who dreads to be judged by the details of the Lord’s commandments? - "Against the Pelagians 2.7"
