All that nonsense about Mary being assumed into Heaven is just that, nonsense. The whole nonsensical argument ignores a very simple truth. Jesus Christ gave John the responsibility of looking out for Mary. John was the last Apostle to die. John wrote several of the Books in the NT. John never mentions Mary having any special role, or authority. Also, John never mentions Mary being assumed into Heaven.
If anything extraordinary occurred with Mary, John would have written about it.
Luke 7:28 I tell you, among those born of women none is greater than John. Yet the one who is least in the kingdom of God is greater than he.”
