Christ is NOT represented by a homosexual priest PERIOD.
You can throw any theology which requires that out the freaking window.
Considering that the statement is coming out of the Vatican (and how nuanced they make all of their statements), his words are remarkably clear and unambiguous. Made in a way as to apply reason to the declaration where the logic cannot be contested.
Had he simply said, "Gay Priests are an abomination," true, he'd make us happy, but he'd set the Vatican up for a firestorm (considering the gay lobby, perhaps the right word would be "a firebombing"). This way, one can't honestly argue with the logic. (The cool part is that one can apply the same logic to the abomination of so-called female priests, as well)
Sort of refreshing...at least imho. But ymmv.
