When I was a boy, I heard a preacher remind his congregation about the true nature of the cross. He observed that we have turned the cross into both a lovely adornment in our sanctuaries and a piece of jewelry for our bodies. It is, for us, a smooth, attractive, gilded thing. But the original cross, he insisted, was nothing like that. The cross that Jesus bore -- and the cross, therefore, that we are invited to take up as his followers -- is harsh and heavy. It is rugged and bloody. It is heavy wood across the back, not silver or gold on a lapel or necklace.
