The Church does not discount either ex nihilio creation nor a Virgin birth. What you haven't explained is why you believe those and yet reject the Real Presence.
Nice twisting of my words there. I didn't say one word about "ex nihilo creation." I said six day young earth creationism. Anyone who can believe that a woman can magically give birth to a child without the participation of a human father can certainly believe the literal truth of everything written in the first eleven chapters of Genesis. The only reason for the discrepancy is that the "virgin birth" is "respectable" and Genesis isn't. That's all there is to it. Scientific theories about origins are based on the assumption that the processes that are gradually bringing about stars, galaxies, volcanoes, islands, etc. today are identical to the processes that brought the heavens and earth into existence in the first place. By this same logic, since all babies require the presence of a mother and a father, the "virgin birth" must also be rejected. But Catholics accept the "virgin birth" and reject Genesis because they are social snobs who look down on "trailer trash."
You knew every bit of this beforehand. Your feigning ignorance makes me wonder about your sincerity.
What you haven't explained is why you believe those and yet reject the Real Presence.
Since I don't believe in chr*stianity in the first place, it's a little unreasonable of you to demand that I believe in the "real presence," isn't it? I also find it difficult to believe that you didn't know this either.
