This is what the Angel said:
[28] ...Hail, full of grace, the Lord is with thee: blessed art thou among women. [...30...] 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.The angle says what will be. Nothing happened yet. But for some reason, Mary does not take it as a prediction of her future child with Joseph:
How shall this be done, because I know not man?
Note: she is more astonished about conceiving a child than about that child having this extraordinary power.
The angel them proceed to further explain, all that in the future sense: "The Holy Ghost shall come upon thee..."
So it is not my own interpretation: Mary is astonished that she, a betrothed woman, will have a child. Go figure.
when are you interested in ‘verbatim’?
Always. Some verses of the Bible are poetical or allegorical, but by default the first interpretation is always literal and even if not, attentive to detail. I am, you know, Catholic: I love, study and obey he scripture as written. If I wanted to spread around my own theories I'd become Protestant and tell tall stories instead.
Some people seem unable to grasp the FACT that if a typical young woman (let's just set aside today's issues with premarital sex, birth control, etc.) who is engaged is told that she will conceive a child, her reaction will be along the lines of, "Of course, my husband and I will have intercourse after we marry and hopefully I will get pregnant very soon."
She would react this way because this has been the NORM throughout history. The ONLY REASON why a woman would react otherwise is if she believed that there was no possibility for her to conceive and, for a young virgin two thousand years ago, this could ONLY mean that she planned to remain a virgin.
People try to pretend that the Holy Family was a "normal" family, but they weren't, they were the most abnormal family ever. Angels of God appeared to both the Blessed Mother and Saint Joseph, they KNEW that their entire lives wouldn't be "normal" because they were being entrusted with the care of the Son of God.
Since you attest to your love for Scripture and your attention to detail, I wonder if you have ever wondered why that verse (Luke 1:28) only says "full of grace" in one (1) English translation of Scripture. It happens to be the Douay-Rheims version. In all others it says "highly favored"; "favored woman"; "favored one"; "favored by the Lord"; or "to whom special grace has been given". Has it ever occurred to you that maybe the Bible didn't really say "full of grace"?
I also find it a little curious that you say the only reason Mary said "How shall this be done, because I know not man?" must mean she never intended to have sexual intercourse. Could she also not have meant that she and Joseph still had some time to go on their betrothal period before they would come together to consummate and the angel's announcement sounded imminent? I think it is the detested "Protestants" that cling more to the Scriptures as written, and don't create their own "tall tales" or "theories" to advance their own wistful legends.
