Are you implying that the meaning was lost in translation?
That's a very common argument, indeed. See here: http://en.wikipedia.org/wiki/Virgin_birth_of_Jesus >The word "virgin" in Christian translations is disputed.

On a related note, the Hebrew word for "wife" and "woman" are the same. And the same is true of Greek. So quotes of Jesus such as http://biblehub.com/matthew/5-28.htm are probably mistranslated, since it doesn't make sense that two unmarried people can commit adultery, so it's likely that the original word was "wife". And yet because of these translations so many young people's sexual desires were repressed so that they might not look lustfully at any woman, married or not. Whenever I ask other Christians about this kind of stuff, they never seem to have a good answer but continue to insist that it should be "woman", and that young men should still not look with lust at any woman.
