the Pope is infallible!
... Or you could just disagree and try valiantly to make sense of the 99,000 other Christian denominations who all disagree over what the Bible actually means.
Or just chuck it all and make yourself your own god.
Let's face it. It's a no brainer. No infallible teaching authority means no truth and no certainty.
So why not stick with the obvious right answer?
Simple, really, isn't it?
Papal infallibility for ever!
PS. and fortunately he is rather a nice bloke, too...
