How does it contradict THIS Scripture:
"Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, just as He chose us in Him before the foundation of the world, that we would be holy and blameless before Him." (Ephesians 1:3-4)
That sure fits Mary to a T.
Wrong. Notice the "us" in the verse...plural...not "she".
This does not connote just Mary, but all believers. John in Revelation says Christ was crucified from the foundation of the Earth; all believers were actually sanctifed before time began in a way.
However, all created humankind are sinners while living in Adam's fallen world in time. The scripture you pointed out does NOT delineate Mary as special.
Yeah, what she said!
