Your point is unScriptural, it has no basis in the faith of the early Christians, and like your defense of the_doc's words it is quite simply wrong.
No praying to the dead is unscriptural.....show me the assumption...or prayers to the dead in scripture...History only God is omnipresent..so only God can be present to all our thoughts and all our prayers at the same time..
Why did God make me.."to know ,love and serve him in this world and the next.." a right on bit of the old Baltimore Catechism...Right now Mary and all of the Saints are doing exactly what they were created for..enjoying God forever.. Rev 19:5 And a voice came out of the throne, saying, Praise our God, all ye his servants, and ye that fear him, both small and great.
