Many of us learn the hard way that the most damning laws and standards are those unwritten ones. The Pharisees, ancient and modern, are masters of using the unwritten standards to club the uninitiated into a coma. An explicit, biblical confession, on the other hand, does not subject the believing community to these secret laws; instead, it liberates us from self-standards and also makes the church open to all under the same standards. Thus a solid confession cleanses from disease and bolsters the immune system with a salutary unity.
