The word anger or angry is a condition and expression of human emotions. It is about as hard to define as the word love. My purpose in this brief summary of biblical texts is not to purely define the word anger, but rather to show in contradistinction to the popular Christian psychological movement that anger is not merely a communicative expression. I ve heard Christians say that anger is expressed by facial contortions or the volume of one s vocal expression or any composure that seems displeasing to the recipient. Then there are those who equate anger with contemptuousness and contentiousness.
Contemptuousness refers to an arrogant and defiant person.
Contentiousness refers to hostility and strife. Anger is a biblical concept associated with that dimension of the soul called the affections in previous centuries, but now generally referred to as the emotions. Any expression of the emotions may be sinful or it may be righteous. The only way that sinful men, and all men are sinful, may interpret an emotional concept is to understand the biblical teaching of that particular concept, whether it is love, anger, hate, et al. God is said to be angry.
