Mary isn't God or like the Father to be worshiped, but she is the Mother of Jesus, His Son and our Savior.
To my understanding, and I'm shooting for the smaller, "be as children" sense of wonderment rather than the Phariseean approach, purpose and need to win arguing the details, she would have to be as purified as a human can be by the Father Himself for this mission and purpose.
Of all in the Biblical story, who comes close to such favor? So, when looking at all of the various flavors of Christianity, I think the Catholics have the best understanding regarding Holy Mother Mary.
For me, these interfaith Cain and Able and Phariseean arguments chase the "be like little children" mentality away, while placing limits on understanding God and His/our Holy Family and limits our recognizing the prophetic signs around us now.
I believe she had a mission in life and has a mission now to prepare the world for her Son's return, hence the sightings, warnings, tears of blood, etc.
God bless you!
Sorry about that...
don’t we already have the warnings in the Bible??
