Who was Saint mary in the Bible?

Mary was a girl living in a rigid patriarchal world who was raped by her husband, a soldier, or some other predator. In the Biblical narrative, that predator was God.

There is no Saint Mary in the Bible.

Mary was a very poluar name back then. There were three "main" Marys in scripture. The predominant Mary being the mother of Jesus. All three Marys however are considered a Saint; that is just someone who is Heaven.

And then there was his deciple that he Mary whom Jesus was the closest to and even received extra blessings and counseling from Jesus.

I think she's the Sainted Mary everyone prays to.
