If you have evidence to the contrary,please post.
LOL! If I have evidence that Mary knew Scripture? C’mon… you’ve gotta admit that you know that you’ve just set up an impossible task! (Not that it proves your point – just that it’s impossible. I might just as well ask you – since it’s
your assertion that she didn’t – to provide evidence for your claim!

)
The discussion was concerning Mary being ever virgin because of your response I assume that you believe she was not.
Why in the world would you assume
that ?!?
I don’t believe that Mary was asking how a virgin could give birth. I believe she was asking how she, who would never know man, could.
Aren’t these the same question, essentially? “How can
I, who is
X, do
Y ?” and “How can
anyone who is
X, do
Y ?” are materially the same question.
(BTW, I think you’ve mischaracterized the debate: it wasn’t “how can a virgin in general conceive?”, but rather, “was Mary saying 'that means that I’m the
almah in the prophecy in Isaiah! BTW… how can
that prophecy come true, given that we’re talking about a virgin?!?”)
And again, BTW… I would assert that, in that time and place,
every observant Jew knew the messianic prophecies and anxiously looked forward to the coming messiah! One didn’t have to be a Scripture scholar to know them…
