<<Nobody knows why Stefanini was rejected by the Vatican. It may have had nothing to do with his predilections and it may have had nothing to do with him.>>
But in your earlier post, you asserted as justification for the Vatican's rejection of Mr. Stefanini's nomination: "The Vatican regularly rejects Catholic candidates whose public status is at odds with Church teaching." Since that does not describe Stefanini's situation, do you have some other theory about why his nomination was rejected?
<<To my knowledge, Callista Gingrich is not in favor of legalizing polygamy and has never suggested that adultery is not morally wrong.>>
What point (if any) are you trying to make here?
