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.

In the Book of Enoch he was in heaven. You may poo poo the book of Enoch but many of your church fathers considered it scripture and Jesus' half brother Jude quoted from it. At any rate, the tradition is as good as anything you would call "sacred" tradition.
So Moses and Elijah were dispatched to the transfiguration from limbo?
