I‘m going to quote, without commentary, what the Pope had to say on Thursday about atheism.
If one basic type of violence today is religiously motivated and thus confronts religions with the question as to their true nature and obliges all of us to undergo purification, a second complex type of violence is motivated in precisely the opposite way: as a result of God’s absence, his denial and the loss of humanity which goes hand in hand with it. The enemies of religion – as we said earlier – see in religion one of the principal sources of violence in the history of humanity and thus they demand that it disappear. But the denial of God has led to much cruelty and to a degree of violence that knows no bounds, which only becomes possible when man no longer recognizes any criterion or any judge above himself, now having only himself to take as a criterion. The horrors of the concentration camps reveal with utter clarity the consequences of God’s absence.
The absence of God leads to the decline of man and of humanity. But where is God? Do we know him, and can we show him anew to humanity, in order to build true peace? Let us first briefly summarize our considerations thus far. I said that there is a way of understanding and using religion so that it becomes a source of violence, while the rightly lived relationship of man to God is a force for peace. In this context I referred to the need for dialogue and I spoke of the constant need for purification of lived religion. On the other hand I said that the denial of God corrupts man, robs him of his criteria and leads him to violence.
