how can a person be both Christian and gay

It's long been my personal belief that Paul was gay. Also that he was schizophrenic. And remember that today's Christianity is much more Paul-based than Jesus-based.

You know the common caricature of the man-hating dyke? I believe that Paul was a woman-hating fag. It's certainly well documented that he was woman-hating (this is probably largely where the decreed celibacy of the Cathoic priesthood comes from), and there are many passages in the Bible that can easily be read as implying homosexuality and that he was ashamed of it (which may further explain priesthood celibacy decree).

But that's just my 2 cents.
