The assumption of Mary
The assumption of Mary means that Mary did not die but directly ascended to heaven in the same way that Jesus did.
We again read in the Catholic Catechism of 1997, Part 1, section 2, chapter 3, article 9, paragraph 6
974 The Most Blessed Virgin Mary, when the course of her earthly life was completed, was taken up body and soul into the glory of heaven, where she already shares in the glory of her Son's Resurrection, anticipating the resurrection of all members of his Body.
Of course the Catholic church has no Scripture to back this claim up and they even admit it. Father William G. Most tells us concerning this doctrine:
There had been a problem of how the Pope could define the Assumption. There seemed to be nothing in Scripture on it, and what things there were in the Tradition of the Fathers seemed to come not from an apostolic origin, but from some apocryphal stories that circulated chiefly beginning in the fourth century. A Pope is not required to specify precisely where in the sources of revelation he finds a given doctrine.
The Catholic church admits that their doctrine of the assumption of Mary is not in the Bible but was made up by the Pope's. The Catholic church puts the value of the Pope's inventions equal with the Scriptures, which is another problem that we will deal with later. When anyone puts the words of a sinful man above the Scriptures, you can only form heretical doctrine.
