As a matter of fact she is mentioned by Acts as being present at Pentecost. And she may be mentioned in John’s Revelation as the lady surrounded by twelve stars. John implicitly mentions her in his prologue, where he speaks of the Word becoming flesh. One does not have to accept Catholic mariology in toto as true to know that Mary played a critical role in our salvation, simply by bearing a child.
Oooo, aren’t you clever. In the same passage as the ascension no less and in a crowd of 120. Now there’s a significant contribution and surely one can draw conclusions from that that she was central to the rest of scripture. Good grief.
Of course she is the mother of Jesus but making up stories not in scripture is dangerous. The woman of Revelation 12 is Israel, not Mary.
