There is no doubt in my mind that you believe that this is what the Catholic Church teaches.
Please cite the Catechism of the Catholic Church to support your belief.
It doesn’t matter what the Catechism may teach, it is what the average rank and file Catholic may believe and practice. Amulets, rosaries, appeals to Mary to interevene, appeals to the power of her purity, the “fullness of her Grace”; The sacred heart images with Mary clutching a thorn briar bound glowing heart?
We get the “wink wink nod nod” of what you say the Catechism says vs. what the people actually do!
Be doubtless all you want; but it was a CATHOLIC who posted "Mary softens the hearts of angry people. And then she guides them to her Son. ♥ "
So the questions comes to you: Is this poster correct or not?
