Wow! Some flowery stuff being written.
Too bad that NONE of it is Scriptural!
That's because Demontfort also says:
3. In answer to her prayers to remain hidden, poor and lowly, God was pleased to conceal her from nearly every other human creature in her conception, her birth, her life, her mysteries, her resurrection and assumption. Her own parents did not really know her; and the angels would often ask one another, "Who can she possibly be?", for God had hidden her from them, or if he did reveal anything to them, it was nothing compared with what he withheld.
4. God the Father willed that she should perform no miracle during her life, at least no public one, although he had given her the power to do so. God the Son willed that she should speak very little although he had imparted his wisdom to her.
Even though Mary was his faithful spouse, God the Holy Spirit willed that his apostles and evangelists should say very little about her and then only as much as was necessary to make Jesus known.
