16. God the Father gave his only Son to the world only through Mary. Whatever desires the patriarchs may have cherished, whatever entreaties the prophets and saints of the Old Law may have had for 4,000 years to obtain that treasure, it was Mary alone who merited it and found grace before God by the power of her prayers and the perfection of her virtues. “The world being unworthy,” said Saint Augustine, “to receive the Son of God directly from the hands of the Father, he gave his Son to Mary for the world to receive him from her.”
The Son of God became man for our salvation but only in Mary and through Mary.
God the Holy Spirit formed Jesus Christ in Mary but only after having asked her consent through one of the chief ministers of his court.
Luke 1:26-38 Douay-Rheims 1899 American Edition (DRA)
26 And in the sixth month, the angel Gabriel was sent from God into a city of Galilee, called Nazareth,
27 To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin's name was Mary.
28 And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women.
29 Who having heard, was troubled at his saying, and thought with herself what manner of salutation this should be.
30 And the angel said to her: Fear not, Mary, for thou hast found grace with God.
31 Behold thou shalt conceive in thy womb, and shalt bring forth a son; and thou shalt call his name Jesus.
32 He shall be great, and shall be called the Son of the most High; and the Lord God shall give unto him the throne of David his father; and he shall reign in the house of Jacob for ever.
33 And of his kingdom there shall be no end.
34 And Mary said to the angel: How shall this be done, because I know not man?
35 And the angel answering, said to her: The Holy Ghost shalt come upon thee, and the power of the most High shalt overshadow thee. And therefore also the Holy which shalt be born of thee shall be called the Son of God.
36 And behold thy cousin Elizabeth, she also hath conceived a son in her old age; and this is the sixth month with her that is called barren:
37 Because no word shalt be impossible with God.
38 And Mary said: Behold the handmaid of the Lord; be it done to me according to thy word. And the angel departed from her.
(shall / shalt is NOT 'asking' Mary if she'll do something for GOD)
(This ain't CONSENTING)
17. God the Father imparted to Mary his fruitfulness as far as a mere creature was capable of receiving it, to enable her to bring forth his Son and all the members of his mystical body.
18. God the Son came into her virginal womb as a new Adam into his earthly paradise, to take his delight there and produce hidden wonders of grace.
God-made-man found freedom in imprisoning himself in her womb. He displayed power in allowing himself to be borne by this young maiden. He found his glory and that of his Father in hiding his splendours from all creatures here below and revealing them only to Mary. He glorified his independence and his majesty in depending upon this lovable virgin in his conception, his birth, his presentation in the temple, and in the thirty years of his hidden life. Even at his death she had to be present so that he might be united with her in one sacrifice and be immolated with her consent to the eternal Father, just as formerly Isaac was offered in sacrifice by Abraham when he accepted the will of God. It was Mary who nursed him, fed him, cared for him, reared him, and sacrificed him for us.
A poor and misleading paraphrase of Gabriel's words to Mary.
For the correction please quote chapter and verse of the visit by Gabriel to Mary.
If there is a Catholic translation that verifies your statement please quote and link that.
What does the "16" signify?
If those are your original words (an opinion at best) fine, but the FR guidelines insist on documentation of quotes from others.
Mary merited NOTHING.
She did not earn it or deserve it any more than anyone else God used to accomplish His plan for redemption of the human race.
God’s plans are not thwarted and no human can do anything to either aid or hinder them.
God alone is sovereign and no human can change that.
