The tension between right and wrong inside church polity.

 Put simply, church discipline is ignored unless it is both horrific and public. Consider how long it took the Catholic church (child pornography and abuse) and the Southern Baptists (pastoral predators) to admit the rot that had taken place in their leadership for so many years. The Presbyterian PCA church, though not as public, has had its own pastoral accountability issues (details).
