I ask the Living to pray. I do not ask the dead nor pray to the dead nor FOR the dead. Let the dead bury their dead. Christ alone LIVES. All others sleep.
Mary is dust, and she will wake up, transformed, the same time as everyone else who has died since Christ. She isn’t hearing prayers, thinking any thoughts or aware of anything that is or has gone on for the last 2000 years. Zippo. Nada. Zilch. None. Nope.
Who said that Mary was dead? Where are her remains?
I believe you are incorrect. Mary was assumed into heaven, after she died. This is celebrated in the Catholic Church as the Feast Of The Assumption.
It wasn't dust who appeared to the three children at Fatima, I might point out.
If so, how is it that he was having a conversation with Jesus (Mt. 17:3) ?
