Nope, sorry, this one is Biblical:
2nd Peter, "become partakers of the divine nature"
And Christ's own commentary on the Psalms, "'I have said ye are gods,' and the Scripture cannot be annulled."
Or are you suggesting not that the Church's understanding of salvation is not grounded in her Scriptures, but that the certitude that the Blessed Virgin Mary is among the saved is 'extra-Biblical'?
Ahhhhh . . . and then the wild haired inferences and extrapolations begin. I read that verse and praise God for it. But I have no exhaustive, precise understanding of what exactly it means and doesn't mean. And neither does any other mortal currently. To insist that one can construe it in an exclusively RC meaning way to support all kinds of Marian nonsense is a leap across Mars biggest canyon on a pogo stick after 24 cans of beer.
And Christ's own commentary on the Psalms, "'I have said ye are gods,' and the Scripture cannot be annulled."
Oh, and this mystery is now pinned down as totally and exclusively proving Mary's elevation to godhead!? Hogwash. Unless every other believer is elevated to the SAME level. In which case, prayers to her and adoration of her a la what has resulted is must be admitted to be an arbritrary addition to one individual vs all the possible others.
Personally, I don't know what the mystery in that Scripture is all about. It clearly is not crucial to understand that Scripture to live my Christian life and arrive in eternity with God The Father. I figure eternity is enough time to grow into whatever that means. I certainly have no compulsion to build a huge tradition encrusted castle on that toothpick of a Scripture.

I don't have a real problem ASSUMING that Mary was Saved. There's every reason to believe she was from all the Scriptural evidence and no Scriptural or logical evidence to think she was not Saved.
But jumping from THOSE sparse facts to all the panolpy of Marian encrusted adoration, veneration and thinly veiled worship is a huge and hazardous leap.
