To be angry is not a sin, for Jesus Himself got angry, as it is written: “And when he had looked round about on them with anger ….” (Mark 3:5). However, to be swift to wrath is a sin, for it is written: “He that is soon angry dealeth foolishly” (Proverbs 14:17) and again: “A quick-tempered man displays folly” (Proverbs 14:29 - NIV).

Therefore, brothers, you must not be quick-tempered but slow to wrath, because – as Wisdom says – “he who is slow to wrath has great understanding” (Proverbs 14:29 – NKJV).

When you get angry with somebody take heed that you don’t speak corrupt words or you don’t lift your hand against him or you don’t make threatening gestures because whereas on the one hand you are allowed to be angry on the other hand you are not allowed to sin, for it is written: “Be angry, and do not sin” (Ephesians 4:26 – NKJV).

Control yourselves, so that you may remain blameless even when you are angry.
