Doesn't anybody read Isaiah anymore? [*cough, cough*]
Is this supposed to be a verse from Isaiah?
LOL.
I am genuinely puzzled how the Protestant insistence that Mary was expecting to sexually consummate her marriage to Joseph squares with their hypothesis that she immediately understood that she was to be the prophesied virgin. It, too, fails the basic logic. Let's say the Isaiah connection was clear to Mary.
-- Mary, you will have a son who will be a great King. It is foretold in Isaiah. You shall remain virgin through it.
-- Impossible: I am already virgin! Explain!
Logical, no?
