[Invincibly Ignorant]

You are correct. the Bible evidence only tells us that Mary was full of grace before Christ was born.

Guess that means she was saved before Christ was born. So it wouldn't be too hard to believe that Enoch, Moses and Elijah were too.

[SoothingDave]

Old Testament figuures were in the Limbo of the Fathers until Jesus came. While they were "saved" by faith in a future savior, they were not truly saved until Jesus opened the gate of Heaven after His death of the cross.

That is, the OT folks had to wait until the Crucifixion to receive the necessary graces to enable them to be clean for Heaven.

Mary did not. She was saved before Christ was even born, saved before she was even born. Not the OT salvation that led to Limbo, but the true salvation that made her ready for Heaven.
