No, not just anybody. Obviously, there have been billions of people who have died, whose bodies we don’t have.
But Mary is a person whose body would have been instantly revered, treasured, and kept, judging by the behavior of the early Christians. Even the Jews of that time, who kept John the Baptist’s body.
Note, there has never even been a CLAIMED relic.
The significance of that is that nobody—not even a fraud—ever thought he would be believed if he CLAIMED to have a relic of Mary. That testifies to the fact that it was universally believed from the earliest days, by all Christians, that nobody COULD have a relic of Mary’s body.
Again, you're making a mighty big assumption there. And it only took to 1950 to make it "official". If it was that obvious it would have been a universal understanding from the get go. But it wasn't universally agreed upon by the ECFs.
Pope Pius XII's previous encyclical Deiparae Virginis Mariae (May 1, 1946) to all Catholic bishops stated that for a long time past, numerous petitions had been received from cardinals, patriarchs, archbishops, bishops, priests, religious of both sexes, associations, universities and innumerable private persons, all begging that the bodily Assumption into heaven of the Blessed Virgin should be defined and proclaimed as a dogma of faith.[citation needed] This was also fervently requested by almost two hundred fathers in the Vatican Council (1869–1870).
Following the example of Pope Pius IX, who canvassed Catholic bishops before proclaiming the dogma of the Immaculate Conception, Pius XII asked all bishops for their opinion. source wikipedia
So the pope conducts an opinion poll to see if this will pass??
"Finally it is our hope that belief in Mary's bodily Assumption into heaven will make our belief in our own resurrection stronger and render it more effective."
Are the Words of Christ and the Bible not sufficient proof regarding our resurrection?
This is my problem with catholicism and Mary....you build so much hope in Mary that she's almost been elevated to a co-redemtrix...which I believe will be the next big thing in the catholic church. There just isn't enough support for it....yet. But it's coming.
