I am sometimes greeted with surprise when people find that I am a vicar and also a scientist. Around 20 years ago, some prominent scientists did try to take on religion but their arguments soon faded, not least because they often attacked ideas of God that few people of faith hold. When I attend scientific meetings to give talks or present data, I always wear my clerical collar. I rarely get a second glance, although some people have thanked me for openly displaying my faith, most recently at a meeting where I spoke in Zurich. Science and faith should not be in conflict if they remember they are asking different questions. Science is a way of looking at the natural world and understanding how it works. It cannot say much useful about the existence and nature of God, because God is above and beyond the natural world. Scientific methods do not work when we encounter the spiritual; that is when we must listen to our souls as they respond to mystery.
