They're merely reporting what the Fathers said. St. Irenaeus of Lyons wrote, around AD 180:
"Consequently, then, Mary the Virgin is found to be obedient, saying: "Behold, O Lord, your handmaid; be it done to me according to your word." Eve, however, was disobedient; and when yet a virgin, she did not obey.... having become disobedient, was made the cause of death for herself and for the whole human race; so also Mary, betrothed to a man but nevertheless still a virgin, being obedient, was made the cause of salvation for herself and for the whole human race.... Thus, the knot of Eve's disobedience was loosed by the obedience of Mary. What the virgin Eve had bound in unbelief, the Virgin Mary loosed through faith."St. Irenaeus was two degrees removed from the Beloved Disciple, St. John. (St. John taught St. Polycarp of Smyrna, who taught St. Irenaeus.)
Thirty years before St. Irenaeus, St. Justin Martyr also compared Mary's obedience to Eve's disobedience.
Compared to that, most Protestant doctrinal distinctives are Johnny-come-lately's.
Uh...
