Too bad abortionists are allowed to flout the authority of the shepherds when creationists aren't.
And btw, the Church does interpret the "new testament" literally. It rejects the literal interpretation of the "old testament" for reasons of theological anti-Semitism.
I reiterate again: the true purpose of the bishops' statement is to attack Zionism. Genesis was thrown in as a fig leaf.
Actually anyone is "allowed" to flout the authority of the Church. You can reject Church authority, the problem comes in calling yourself Catholic. Lots of people do though and I think its scandalous that more Bishops don't distance themselves from the likes of Teddy Kennedy and Teresa Heinz.
As for your other contention, you are entitled to your opinion but it's not plausible to me.
