As a bishop and cardinal he use to lash out strongly against gay marriage. Somebody in the Vatican is yanking his chain.
Here's what I think: When apologists make arguments proving Papal Infallibility, we are often confronted with bad popes from the past, like the Borgias. Part of our argument includes admitting that we have had a few bad popes, and how that does not have a bearing on the doctrine.
Well, I say we have a bad pope now. He is certainly not a Borgia, but he has bad political leanings for sure. But until he tries to dogmatically define something erroneous Ex Cathedra, Catholic doctrine still stands regardless of his personal remarks.
