Freedom that lacks moral truth becomes its own worst enemy.

Optimism and pessimism are mere matters of optics, of how you look at things, and that can change from day to day, or with a new prescription for your glasses - or with a new set of ideological filters.

"You don't believe what you read in the papers about anything else; why do you believe it about the pope?" That's where I'd start.

When climate change gets some attention in a 100-page document, the most important parts of which will have to do with the theology of stewardship and the theology of "human ecology," it's almost certainly going to be rapturously embraced, or bitterly opposed, as a "global-warming encyclical," despite the evidence that it's much more broadly gauged than that.

More pro-active Vatican communications might be able to do something about all this, but when the Holy See is constantly in the mode of, "No, what the pope really meant was . . . ," the game has already been largely forfeited.

But ripped out of context, ["Who am I to judge?" phrase] has become an all-purpose filter through which everything else - including the pope's multiple reaffirmations of Humanae Vitae, Paul VI's encyclical on the morally appropriate means of family planning - gets airbrushed out of the picture.

The short-term impact is that people are encouraged to give the Church another look. It's up to the liveliest parts of the Church - the dynamically orthodox parts of the Church - to seize that opportunity.
