Augustine of Hippo, on Matt 5:20

“For I tell you, that unless your justice abound more than that of the scribes and Pharisees, you shall not enter into the kingdom of heaven.”

“(ubi sup.) In the third case are three things; anger, the voice expressive of anger, and a word of reproach, Thou fool. Thus here are three different degrees of sin; in the first when one is angry, but keeps the passion in his heart without giving any sign of it. If again he suffers any sound expressive of the passion to escape him, it is more than had he silently suppressed the rising anger; and if he speaks a word which conveys a direct reproach, it is a yet greater sin.”
