Dude....do you read the text or just repeat the talking points?? Is this really what they teach priests in catholic seminaries???
The context of Matthew 1 and Luke 1 will put things in perspective.
There is no vow of chastity in anything Mary said.
When she was told she was going to have a baby she knew she and Joseph had not engaged in sexual intercourse as they were not living together as husband and wife...she also knows they hadn't been having sexual intercourse period nor had she had it with anyone else.....so she's trying to figure out how this is going to happen.
This speaks to the upbringing that both Joseph and Mary had. They were honoring the Law and not committing adultery. Joseph is described as a righteous man by Matthew. We know Mary had a strong upbringing in the things of God by her knowledge of the Scriptures.
Then Gabriel tells her how it will come about. He also tells her Elizabeth is pregnant as well.
When Mary hears this she tells Gabriel, "behold, the bondslave of the Lord; be it done to me according to your word."
Now we turn to the story in Matthew for a timeline and background of Joseph and Mary's relationship.
Matthew 1:19 (NASB)
Now the birth of Jesus Christ was as follows: when His mother Mary had been betrothed to Joseph, before they came together she was found to be with child by the Holy Spirit.
Same verse except in Douay-Rheims
Now the generation of Christ was in this wise. When as his mother Mary was espoused to Joseph, before they came together, she was found with child, of the Holy Ghost.
They were considered to be married for all practical purposes except in actual practice. However, we gather from the text they were not living together as husband and wife.
Matthew 1:20 the angel tells Joseph not to be afraid to take Mary as his wife.
Matthew 1:24 notes they actually married.
NASB
And Joseph awoke from his sleep and did as the angel of the Lord commanded him, and took Mary as his wife,
Douay-Rheims
And Joseph rising up from sleep, did as the angel of the Lord had commanded him, and took unto him his wife.
Instead of hurling abuse, how about sticking to the subject?
Read Luke’s account. Mary is, by our standards, already married. She has just been told by the angel that she is to conceive and bear a child.
THE ANGEL HAS NOT TOLD HER SHE IS ALREADY PREGNANT. NOR HAS HE TOLD HER SHE IS GOING TO BE PREGNANT WITHIN MINUTES.
Her question to the angel makes no sense if she expects to be engaging in relations with her husband in the near future.
