Hi James. In a short answer, I would say yes and no, as are most things with Mary. There is very little about Mary in the Scriptures and much of Mariology and Marian devotion is a development later in the Church which becomes a part of the living Tradition. However, we do see in the Scriptures that Mary was highly favored by God, Jesus turned her over to us as our mother too, etc.

I’m no expert in Marian doctrine so I am hesitant to answer in more detail, especially definitively, but what I wrote is the jist of it. Does this help at all?
