I think it is also note worthy that Jesus gave John the responsibility to take care of Mary and it was John who was the last writer of Scripture and the last Apostle to die. If anyone would have known of any note worthy events surrounding Mary it would have been this Apostle.
The views on Mary by RC's are just one example of what happens in a centralized authority structure when leadership is corrupted. We see it today as the current pope is steering his church to the radical left. Ultimately, RC's will fall in line with whatever they are told because they are indoctrinated from early on that their salvation is dependent on their loyalty to their church. As these events unfold it's a great reminder why the Apostolic Era churches were decentralized.
Not one word about Mary from John or any other writer. She was obviously insignificant to them. Yet the Catholic Church has built much of it's belief structure and practices around her. It's actually pagan in origin probably begun around the goddess Diana to attract the pagans into the Catholic belief system. Paul already was having an issue with the economics built around the worship of Diana and the trinkets being made and sold.
