Of course he doesn't.
In all the years I've been Catholic, I never learned that the Pope, or any priest or nun spoke for me. A pope is merely the vicar, the successor of St. Peter, the shepherd who continues to guide us along the path that Jesus took and wanted us to take.
That's how I learned it.
A Congressman or POTUS doesn't speak for me either.
Even an attorney doesn't speak for me. S/he pursues a legal cause for me but doesn't speak for me.
Guide us to socialism? How’d that work out for Cuba? Venezuela?
