"What Pope Francis "is doing all in his power" is being the Head Pastor of Christ's Holy Church."

So, according to you, just by being the Head Pastor of Christ' s Holy Church, Pope Francis is already doing all in his power to fix the child sexual abuse crimes by priests and cover ups by Bishops scandals. Your reasoning is the perfect excuse for Pope Francis to have done next to nothing so far to fix such scandals.

"...but NO earthly authority can -fix- anything that happens at the ground level. That can only be -fixed- by those at the ground level."

Your statement above does not make sense.  The same can be said of Pope Francis' Christian strategy to fix the child sexual abuse scandals.
