"Since her assumption into heaven, sworn to by the Bishop of Jerusalem, Never happened. Never taught or believed before 500s AD.
Please listen to your Pope.
Pope Benedict XVI (Ratzinger) writes...
"Before Mary's bodily Assumption into heaven was defined, all theological faculties in the world were consulted for their opinion. Our teachers' answer was emphatically negative... Altaner, the patrologist from Wurzburg…had proven in a scientifically persuasive manner that the doctrine of Mary’s bodily Assumption into heaven was unknown before the 5 century; this doctrine, therefore, he argued, could not belong to the “apostolic tradition.
And this was his conclusion, which my teachers at Munich shared. - J. Ratzinger, Milestones (Ignatius, n.d.), 58-59. .
(Saint) Bishop Macarius swore in a letter to Saint Helena that the Virgin Mary was assumed into heaven, in reply to Helena's request for the remains. He said he was sending the Virgin Mary's grave clothes and coffin, but could not send the body because of her Assumption into heaven. This letter would have been dated approximately 326-328 AD, when Helena went to Jerusalem to recover as many relics of Christ's life and passion as possible. There are quite a few historical accounts about Helena's efforts from that time and later.
Even Ratzinger didn't trust his teachers as incapable of error, since some of them even doubted Jesus ever lived!
