I dunno... The RCC hitched it's wagon pretty tight to the whole "Mary was ever-virgin, and we are infallible on stuff like that" thing.
They'll spin this as well and as desperately as the clintons did, but just as a little blue dress exposed the lies of King Willie (for those with eyes to see) -- mighty Rome will forevermore be mocked by a little stone box with a few simple words carved into it.
I love how God works sometimes.
