" . . . Catholics ask Mary to do only what God has the power to do?"
Only God can pray to God?
That's what you're saying and it's just plain stupid.
Jesus Christ told us to pray and we're told to pray for one another. The real issue is whether or not someone believes Jesus Christ was telling a lie when He said He is God of the living not of the dead.
People who have no life in them always end up directly contradicting Jesus Christ, though, so we understand. We'll pray for you and ask Mary to pray for you as well.
What do you think Catholics ask Mary to do for them?
Let’s start with your level of knowledge, first.
Your damning arrogance is in presuming to know who has Life in them and who doesn't.
Maybe Mary informs you of who the lifeless pagans are, even when you don't know them.
Yes...TO HIM...Not Mary...
