What book in the Bible is the assumption in?

Answer 1

None, but you might consider these historical realities:

Pope Gelasius in 495 A.D. declared by Papal Decree, an anathema upon all those who would choose to adopt the heresy of the "Assumption of Mary" as a dogma in the Church, this decision was again supported by Pope Hormisdas of the 6th century, when the heresy began to resurface. Yet in 1950, Pope Pius XII in contradiction, infallibly declared this heresy "official Catholic Doctrine which all Catholics are required to believe"! Which Popes were correct. Is the "assumption" even mentioned once by the early Church fathers that were taught by the Apostles or their students? I have been told that centuries later (by the first millennium) the Orthodox had accepted it as well. Irenaeus, Jerome, Augustine, Ambrose and the others Church Fathers said nothing about it. Writing in 377 A.D., church father Epiphanius states that no-one knows Mary's end.[3]

"The belief in the corporeal assumption of Mary is founded on the apocryphal treatise De Obitu S. Dominae, bearing the name of St. John, which belongs however to the fourth or fifth century. It is also found in the book De Transitu Virginis, falsely ascribed to St. Melito of Sardis, and in a spurious letter attributed to St. Denis the Areopagite" (Catholic Encyclopaedia).

The first church author to speak on the assumption, Gregory of Tours, based his teaching on the Transitus, perhaps because he accepted it as genuine.[4] However, in 459 A.D. Pope Gelasius issued a decree that officially condemned and rejected the Transitus along with several other heretical writings. Pope Hormisdas reaffirmed this decree in the sixth century.[5] It is ironic that this heretical teaching was later promoted within the Catholic Church, until eventually it was proclaimed a dogma in the twentieth century.

It was made a dogma around the mid 1900's and even though it was never taught by Jesus or the Apostles or even by any of their students for 300 years and previous Popes had declared it an anathema it is now "required" if you are Roman Catholic.

Answer

Put simply, the assumption of Mary is a belief held by Roman Catholics as well as some other denominations that Mary, at the end of her life, was physically taken up into heaven.

This doctrine cannot be found anywhere in scripture. Revelation 12 is the nearest that The Bible comes to the doctrine, but this is only even remotely relevant if a particular (and some say, bogus) interpretation is placed on this reference in the Bible. There were some references that date from the 4th Century, but these are apocryphal to say the least, and most regard these references as very suspect.

For most non-Catholic Christians the doctrine of the Assumption is heretical and is seen by them as yet another human invention (along with purgatory, limbo and many others) of the Catholic Church.
