Christians believe that moral authority flows ultimately from God. The personal misbehavior of people God employs to speak moral truth may give some a convenient excuse to ignore that truth, but the truth is the truth no matter what sort of scumbag happens to be proclaiming it.
There are folks that worship an invisible Christ, and those that worship visible, man-made, unbiblical religious structures and institutions.
Institutions fail, men fall, as do the organizations that hire them for pay. Acting LIKE Jesus, guarantees moral authority. NOT acting like him, diminishes it, regardless of the particular and peculiar claims of verity and truth, the organization one is a member of makes.
I strongly support YOUR right to believe it your way. I also strongly disagree with the RC position on their own "moral authority" in this matter. Pedophiles do NOT represent Christ. Neither do organizations that provide them with cover and employment. THAT is what I believe.
Taking the body of Christ from the hands of a man who, moments before has been fondling the unmentionable aspects of an altar boy's privates... is blasphemous to some of us.
