Ya know, I gotta say, I don't find it much comfort to hear that "well, other denominations are losing adherents too."  (As bad as the "well, other people abuse children too" with the implication that the hierarchy is somehow excused from the abuse and cover-up.)  The overall drift away from Catholicism and other Christian denominations suggests a bigger overall problem.  Christianity began and grew in the midst of a decadent secular Roman society, so frankly, it's not society's fault.  I can't help thinking too many supposed Christian leaders have become too wrapped up in trying to dominate society with secular power rather than leading by spiritual example.
