Karol Wojtyla, Pope John Paul II, has been a devoted son of Mary ever since early youth, when he worshiped at her shrines in the neighborhood of his native Wadowice. During the Nazi occupation of Poland, as a chaplet leader in a "living rosary," he joined in prayers to Mary for peace and liberation. He also studied the works of St. Louis Grignion de Montfort (1673-1716), from whom he takes his motto as pope, totus tuus ("I am wholly yours").
It would be a mistake to think of the pope's attachment to Mary as the fruit of sentimentality. He emphatically denies that Marian teaching is a devotional supplement to a system of doctrine that would be complete without her. On the contrary, he holds, she occupies an indispensable place in the whole plan of salvation. "The mystery of Mary," writes the pope, "is a revealed truth which imposes itself on the intellect of believers and requires of those in the Church who have the task of studying and teaching a method of doctrinal reflection no less rigorous than that used in all theology."
The pope's understanding of Mary
When the Pope speaks he teaches!
God used Mary for His plan, in this I agree.
Also God used John the Baptist, Apostles, prophets, David, Moses, Abraham etc...
And with that comes John 19:30.
You seem to post many things that do not prove what you claim, and you show every plan of not understanding that failure.
