Sometimes, a holy anger happens for God’s sake, but it does not have nervousness and loss of temper, it is a holy zeal.
James, the apostle, said about human anger “…for the wrath of man does not produce the righteousness of God.” (James 1:20) Our saintly fathers, have many sayings on rebuking anger.
St. Aughoris said, “The prayer of the angry is a defiled and rejected incense and the offering of the angry is unaccepted.” He also said: “Anger is an action of the insane… It makes humans like beasts… the eyes of the angry are evil, full of blood, while the face of the gentle is radiant and his eyes look with dignity.”
St. Agathon used to say, “Even if the angry raised the dead, it is not accepted by God and nobody will come forward to him.”
