Be not hasty in your spirit to be angry: for anger rests in the bosom of fools.
All Commentaries on Ecclesiastes 7:9 Go To Ecclesiastes 7
Gregory The Dialogist
AD 604
When the peace of the mind is lashed with anger, torn and rent, as it were, it is thrown into confusion, so that it is not in harmony with itself and loses the force of the inward likeness. Let us consider, then, how great the sin of anger is, by which, while we part with mildness, the likeness of the image of the Most High is spoiled. By anger, wisdom is cast off, so that we are left wholly in ignorance of what to do and in what order to do it. .
