“Tribes are a normal part of life. They can be as simple as a high school hockey team or a label like ‘Presbyterian.’ Our family is a mini-tribe. Tribalism turns a tribe into a center of worship. Tribes tend towards tribalism, largely because that’s what the heart does. In tribalism, the tribe then becomes not just an affinity grouping but a source of life. In short, the tribe becomes an idol. It’s easy to see tribalism in others, but it’s hard to see our own.”
