As ever, the Cigoña blog got it right here. Whether Bishop Sanchez Sorondo should be described as a cretin, whether his comments should be described as rubbish, whether he is more of an imbecile than Fisichella, are questions of vocabulary and register, but the sentiment is right.
The Bishop is Chancellor of the Pontifical Academy of Sciences, and of the Pontifical Academy for Social Sciences, so might be presumed to know a thing or two. He especially might be expected to know a thing or two about global warming, and, as a fellow Argentine might have had a chat with the Pope before the latter made his recent comments about
"Once the Pope has taken a position, it becomes part of the Magisterium of the Church, whether we like it or not. It is part of the Magisterium just as the fact that abortion is a grave sin is part of the Magisterium."
How very wrong this is: Steinbeck says somewhere something like: "you have to be very clever to be that stupid". What happens when the Pope decides that diesel cars put far more greenhouse gases into the atmosphere than petrol ones: does that become part of the Magisterium? Does my Mondeo Estate become a mortal sin?
One effect of this very Latin American papacy is that the sort of carefully described and nuanced differences between the value and importance of papal statements has been thrown away, to be replaced by a sense in which they are simply what the Boss said, and therefore to be enforced by his enforcers.
Either the Pope knows this sort of thing is going on and doesn't care, which would be scandalous; or he doesn't know, which would be scandalous.
God Help Rome, and all of us.
