In Which We Forgive Those Who Don’t Deserve It, Because We Don’t Either
Anger is unique among the seven deadly sins in that, in general, anger isn’t even a sin (cf. Ephesians 4:26). At one level, it is simply an emotional reaction to having our boundaries crossed. And at the highest level, anger is actually a virtue, since it is a significant part of God’s character — i.e., the “name” to which we are being conformed!
At the same time, anger is also the name of one of the most violent and dangerous sins. We can define sinful anger as a self-righteous passion for punishing those who offend us. This is why anger is so empowering and so deadly: it magnifies the sins of others to the point where we ignore our own.
Because anger is so devastating, we need to combat it with both meekness — the ability to restrain our passions in submission to God’s rule — and peacemaking, which seeks restoration and reconciliation instead of revenge.
Of course, that is easier said then done…
