You are if you want to make someone a saint! :) This happens all the time, so you must hold many recent miracles as genuine.
I never said I didn't believe in the Virgin Birth - I said science cannot prove or disprove it. It is a statement of faith, which, as a Catholic, I accept.
Since they did not have in vitro technology, why can't science disprove a virgin birth 2000 years ago?
Even those I am not REQUIRED to believe. The Church states that there is substantial and reasonable evidence to prove that a miracle took place. But as a Catholic, I am not absolutely required to place my faith in private miracles, even those declared suitable for belief by the faithful. Personally, if the Church has examined such claims suffiiciently, then I would go along with their findings. However, there is always room for some doubt on such matters BEFORE that happens - there are too many phonies out there.

How are you going to disprove it? It was not observed by science. All of science's hypothesis, laws and theorums are based on observation. Using observation, they come to a conclusion on what will LIKELY happen in a similar circumstance, either from the past or the future. Since science did not observe and record the Christ's conception, science cannot disprove anything. They base their theories on presumptions of observation of other similar events - which doesn't mean that a unique event could happen that is outside of their observational datum.
