Don't forget that the "religiosity" in the countries that are the historic home of the church is also very poor. You go into a Cathedral or Basilica during mass in most places in Europe and all you find are old ladies. Basically, the home base of the Church has abandoned the Church.

Coincidentally those places are also technologically and philosophically sophisticated, places that do care about the future by definition. Yet they also tend to have low birthrates. The Church is simply taking advantage of these two situations in a campaign to explain a short term (though sizable) economic blip which is already reasonably explainable in ways that don't conform to the obvious ideological footprint the Church is trying to fit all this into and for all appearances looks to already be on the upswing anyways.
