I often hear the term “cafeteria Christian.” It is a description of our current religious milieu. People pick and choose what’s important to them in their faith. It’s usually said with disdain—and a bit of eye-rolling.
Theologians, who construct systems of belief, want to think about theology as a whole. They are afraid that a generation is going to come along and jettison a couple thousand years of careful thought in lieu of what feels good to them.
