Speaking of the EU, Pope Benedict said last March, "A community that constructs itself without respect for the authentic dignity of the human person, forgetting that every person is created in the image of God, ends up by not being good for anyone . . .This is why it appears increasingly more indispensable that Europe should guard itself against that pragmatic attitude, widespread today, which systematically justifies compromise on essential human values, as if the acceptance of a presumably lesser evil were inevitable . . ."*
The "common good" if the premise is wrong, as it currently is in the EU, becomes a "shared ill".
As you say, that applies here to. On this subforum in fact. Look at the abortion threads. How often do we hear, in effect, that a person is better off not being born? That an infant will be consigned to a life of misery, or that a woman will be forced to give up this or that? (your thread about the poll ESPN did on the rising number of college women who abort their babies to save their athletic scholarships is a good example of that mindset).
I know you and I are far apart theologically. And both of us are not Catholic. But we both agree, I think, on the position of Bishop Betori and the Pope on these issues.
Secularism detached from faith is dangerous. All Christians should be able to share that opinion. While Christianity unity is not immanent, we can come closer to unity by reviving the Christian humanism which was, until recently, a defining trait of Western Civilization. St. Thomas, Dante and the progressive, three time Democratic Party candidate for President, William Jennings Bryan, were Christian humanists. Bryan was a liberal, he fought the conservative faction in the Democratic party. Bryan's fundamentalism and Thomism are far apart theologically but socially, materially, similiar.
The president of the Italian Senate and philosopher Marcello Pera, a secularist himself, has proposed something along the line of a return to Christian humanism. He, writing with then Cardinal Ratzinger (who disagreed with him), proposed a Christian civic religion for the EU in which non-believers would find it to their benefit to participate. Ratzinger, in contrast, hopes exceptional Christian individuals will emerge who will pull the EU out of its death spiral.
Other alternatives are, in my opinion, rather grim.
