Pseudo-Chrysostom
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.
He who is angry without cause shall be judged; but he who is angry with cause shall not be judged. For if there were no anger, neither teaching would profit, nor judgments hold, nor crimes be controlled. So that he who on just cause is not angry, is in sin; for an unreasonable patience sows vices, breeds carelessness, and invites the good as well as the bad to do evil.
