I'm not a theologian, and I must say honestly that Vatican astronomers' views [on astronomy] are entirely in accord with ours. I'm not aware of any Church positions that contradict modern science. In my own life, my science and my religion are separate. I'm Jewish, and so religion to me is a kind of moral code and a kind of history. I try to do my science in a moral way, and, I believe that, ideally, science should be looked upon as something that helps us understand our role in the universe.
