Jesus died but rose from the dead = possible.
Jesus ascended bodily into heaven = possible.
Jesus' mother taken bodily into heaven = impossible.
Not at all. I'd say it goes like this:
Jesus died but rose from the dead = recorded in Scripture.
Jesus ascended bodily into heaven = recorded in Scripture.
Jesus' mother taken bodily into heaven = not recorded in Scripture; not even hinted at in Scripture.
Mary was about 15 when she was betrothed to Joseph, so she gave birth to Jesus at age 15 or 16. Jesus was crucified when he was 33 or so, meaning Mary was about 48 or 49 by then. It is generally agreed that John wrote the Gospel of John c. 90 A.D. At that point, he wrote, “And NO MAN has ASCENDED up to heaven, but He that came down from heaven, even the Son of man which is in heaven” (John 3: 13). If one assumes that John did not mean that his use of “man” excluded women, then Mary would not have yet been assumed into heaven and would be at least 105 or 106 years old. Of course, maybe her assumption happened after that.
