It’s interesting.
Another possibility never mentioned about Mary.
God may have buried her to avoid having her body picked apart by idolators.
"...We wish to know if you, Venerable Brethren, with your learning and prudence consider that the bodily Assumption of the Immaculate Blessed Virgin can be proposed and defined as a dogma of faith...;_Deiparae Virginis Mariae.
1946. Pope Pius sends a letter to the bishops of the world concerning the Assumption of Mary.
In order to respond to the Pope, the bishops needed to determine the source of the belief in the Assumption of Mary. Was it just a legend, believed by a few Catholics? Or was it a part of the deposit of faith, revelation handed down from the apostles? The Church could only define it as dogma if it were the latter. SO where do the bishops search for the answer? Scripture and Tradition. Of course, Scripture had no teaching of Mary's death, burial, resurrection, or Assumption. So on to Tradition they went. And that's where they found their doctrine on the Assumption of Mary. With supporting Scripture that is NOT explicit, but IMPLICIT. And can only be understood by those who contemplate and study and ponder these things in their hearts. The faithful and their "supernatural appreciation of the faith" . the sensus fidelium, the concensus of faith. It is an "...instinctive sensitivity and discrimination which the members of the Church possess in matters of faith. In that which the faithful hold in common to be the true Catholic faith, they are infallible and "cannot err in matters of belief."
