Oh now that’s a hoot. A Catholic trying to explain how others are using the Bible wrong. I’m sure that right after the tell us how we interpret the Bible wrong they will explain how the Bible contains the story of the bodily assumption of Mary or that she was installed as queen of heaven.
Non Catholics normally use the Bible wrong. The difference is that private interpretation is Scripturally forbidden.
The whole Mariology thing is partially extra Scriptural, yet believed from the first century by the Faithful. Same as iconology. St Luke was the first to write (paint) an icon - that of Mary - and yet we have the Protestant iconoclasts (born of Islam) who wail and gnash their teeth against icons to this day.
