To believe is easy. You can fill stadiums with people wanting to believe, either to solidify what they already think or to grasp hold of something because they feel cast adrift and lost at sea.
To doubt, to interrogate your fear, to really question what you believe, that’s difficult. It’s difficult because we want to protect ourselves from doubt and unknowing. Indeed when we encounter somebody who is different from us, our first experience is often to see them as monstrous, as having beliefs and practices which are alien and stranger and historical and contingent. When we encounter them we either want to consume them, make them part of our social body, or we want to vomit them and get rid of them. Or perhaps we want to have some sort of interfaith dialogue where we can talk about where we agree.
