Book excerpt: In the Sermon on the Mount, Jesus puts aside his usual parables and speaks plainly in language anyone can understand. Like Francis of Assisi and others, Arnold chose to live out Jesus' teachings by embracing their self- sacrificing demands. In this collection of talks and essays, he calls us to live for the Sermon's ultimate goal: the overturning of the prevailing order of injustice. In its place, Arnold writes, we must build up a just, peaceable society motivated by love.
