Augustine of Hippo
Catena Aurea · Matthäusevangelium 5
For I say unto you, That except your righteousness shall exceed the righteousness of the Scribes and Pharisees, ye shall in no case enter into the kingdom of heaven. Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment: But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
(ubi sup.) Here we have three arraignments, the judgment, the council, and hell-fire, being different stages ascending from the lesser to the greater. For in the judgment there is yet opportunity for defence; to the council belongs the respite of the sentence, what time the judges confer among themselves what sentence ought to be inflicted; in the third, hell-fire, condemnation is certain, and the punishment fixed. Hence is seen what a difference is between the righteousness of the Pharisees and Christ; in the first, murder subjects a man to judgment; in the second, anger alone, which is the least of the three degrees of sin.
