Frank Schaeffer:

If there is one thing all Christians should have learned by now, it's that we -- of all people -- should never, ever cast aspersions on anyone else's sex life.  When it comes to pointing the finger over sexual "sin," the worldwide Christian community -- from the halls of the Vatican and many a Greek, Russian, or Arab Orthodox bishop's palace, to an Evangelical "home church" established in somebody's basement two minutes ago -- is in the morally compromised position of a violent habitual rapist criticizing a shoplifter for stealing a candy bar.
