Would that be the abridged, heavily edited version of Scripture circa 1611 AD, or the original unabridged, unedited version from 405 AD?
How about those books & letters that were generally accepted as scripture even earlier than that. For that matter - absolutely NONE of the books, Old Testament, New Testament, or even the Deuterocanonical books (Apocrypha) teach that Mary was the “Mother of God”. So there’s a starting point.
Another, very much related, would be the “perpetual virginity of Mary” and the “immaculate conception of Mary), which again is not recorded in ANY book, pre or post-1611.
Both of these originated in the writings and teachings of “church fathers” far after the apostolic age (death of the last of the first-century apostles).
