My own reading and discussion indicates that RCC doctrine is an ever evolving system, and because of attributing certain things to Mary such as perpetual viginity (some believe Jesus didn't even pass through the birth canal as with normal births, but miraculously passed through the wall of the womb) and sinlessness, they then had to develop the whole idea of the Assumption....I say develop, but I think I mean invent.
Studious gave a good answer...Also in Jewish thought one has to see that Jesus became the once and for all sin-offering for ALL mankind...for both Jews to whom the Temple and sacrifice system were well known and part of their life...and to Gentiles who were untaught and afar off.
Yes praise G-d that the Father sent the Son to pay the price for our sin and to give us the gift of eternal life....the very thought of which is a life-long meditation of blessing.
Besides the fact that Mary's body disappeared - per witnesses - and likely during the lifetime of St John who may or may not have been so excited by this news that he told someone in his letters in the NT - that he had good news to share face to face.
That all aside - if her assumption was invented...
So was Elijahs, Henochs and Moses.
Who were - as i tried to point out at least twice previously, precursors to how God can and does work.
He works outside of time and space.
The Gospel shows us Jesus standing with Moses and Elijah - and them also in their glory and yet this is before His death and resurrection.
Now plainly, if you follow what i am telling you, you will eventually grasp how this leads to Mary's own Body going to Heaven also.
Certainly the woman who was filled with a unique grace and the mother of the Lord [Who is God] - would be received into Heaven - if Jesus were to take the other three first.
And again, after Jesus does and rises, we call Him the First Fruits of Heaven because He opened the gates.
SO why did He show them Moses and Elijah in their glory before He opened the gates to Heaven??
Thats the million dollar question .
Answer:
He was showing, if one can see, that He is outside of earthly time. He is not constrained to our perceptions and our own 'natural' law that He doesnt subscribe to.
NOW i KNOW my posts are boring - long winded and whatever...
But take the time to read them... and this one again, slowly.
Being that He was proving He is not tied to our way of doing things, that not only does the greeting to Mary mean something of her character's sinlessness, and being 'presaved' by her Son as though already washed by baptism, but she enjoyed that state prior to the greeting of the Angel.
And not only is Jesus the first fruit of Heaven, and Moses and Elijah and Henoch enjoyed the glorious state prior to His death and resurrection on earth, but there is no way Moses, Henoch and Elijah could have made it to Heaven first if God doesnt work outside of human time.
OR scriptures and the Apostles would have lied by calling Him the first fruits - since it is evident Moses and Elijah were already there.
Stop thinking in the practical and putting God in a human box that He must conform to us, He just wont.
See the singnificance of what i am telling you.
And there is nothing in all of scriptures to suggest it would be impossible for Mary to be assumed into Heaven bodily...
In fact, scriptures of the OT and NT show it is not only possible, but for her, definite.
