The Christian church is one of the few organizations in the world that requires a public acknowledgement of sin as a condition for membership. In one sense the church has fewer hypocrites than any institution because by definition the church is a haven for sinners. If the church claimed to be an organization of perfect people then her claim would be hypocritical. But no such claim is made by the church. There is no slander in the charge that the church is full of sinners. Such a statement would only compliment the church for fulfilling her divinely appointed task
