Do be do be do
Fr. Bob Carr ruminates about why the slogan "What Would Jesus Do?", a currently popular theme in Evangelical Protestant youth culture, never really sat quite right with him. He offers a story to illustrate why we need not just the question, but also the answer. He starts here and gives a followup.
For what it's worth, here's another angle: "WWJD?" by itself is a question about morality, and while moral guidance is good, it's not everything. Sometimes we get the guidance and we still fail to live up to the way of Jesus. Another question comes to help us out: "What did Jesus do?" He became an inexhaustible fountain of forgiveness for us. We listen to the answers from Jesus the Preacher, but we also need Jesus the Priest.
