Knowing what we know now of our environment, the earth, and its place in the cosmos (we are but a speck, really), the very concept of a human-centred "religion" is untenable. In fact, it is downright suicidal. So a few pronouncements here and there is not going to change anything. Reannouncing that the God of Jesus and of Mohammed and of Abraham "may" offer some ideological solace to certain groups in the very short term but it's a dangerous waste of time since it deludes us into a comfort zone that isn't one. There needs to be a huge change, which won't happen, since any change will more than question the validity of the Catholic Church's existence.
Faith is one thing; the business of faith is a different beast altogether.
