And Jesus said, “You have heard that it was said to the men of old, ‘You shall not kill; and whoever kills shall be liable to judgment.’ But I say to you that everyone who is angry with his brother shall be liable to judgment; whoever insults his brother shall be liable to the council, and whoever says, ‘You fool!’ shall be liable to the hell of fire.”

Those of us who have brothers or sisters or spouses can take little comfort from those words of Jesus. With those close to us getting angry, hurling insults, and yelling “You fool!” (or more likely “You idiot!” which expresses the Greek better) comes as second nature.

In fact, if we’re honest, the entire Sermon on the Mount (Matthew chapters 5 to 7) stands as an enormous challenge to the way we do most things most of the time.

This summer at PEAK, Wyoming Catholic College’s high school program, theologian Dr. Jeremy Holmes taught the Sermon on the Mount.
