G-d feels welcome and at home in a harmonious atmosphere. On the negative side, the consuming fire which devours the conflicting couple may in fact be the fire of anger, which in its venom provokes diatribe and insult and leaves the relationship in a state of turmoil. The propensity to anger is generally condemned as evil and one is to keep far away from exercising anger. Anger as verbalization that lacks control, is placed on par with idolatry, which also emanates from lack of control and is instead the expression of what one feels like doing. Anger begets angry counter-response, as well as implanting a hardness and arrogance which makes one oblivious to the truth and unconcerned about others.
Anger is a destructive enough force in human relations.
For the married couple, who are in an enclosed environment, it can be devastating. Anger is verbal violence, and the fear engendered by anxiety over when the next tantrum will come puts the entire house on edge. Where respect builds, anger destroys. Where true respect prevails, anger is not likely to come into play, for it is not usual to explode at people whom one really respects. The presence of anger thus points to a double deficit, in that the proper respect that should obtain in the marriage is sorely lacking.
