Don't underestimate the power of symbols; people's entire subconscious functions on that level.

There actually are a lot of liberal Christians for example who hold their faith quite loosely and non-literally. Their faith isn't pointless; it provides them with belonging, refuge, and incitement to be egalitarian and inclusive and to perform charitable works.

On a worldwide basis, last I looked, only about 17% of Christians identify as evangelicals. So it is almost a certainty that most Christians are less rigid than evangelicals concerning literalism, inerrantism, and authoritarianism in their religion.

I still consider liberal Christianity way too crufty for me to want to play in that sandbox. It still lacks a sufficient commitment, in my view, to critical thinking. However ... I do not discount the power of its appeal to many people.

Even as Catholic (and a more "Evangelical" Christian), I viewed the Trinity as a symbol. Despite my exit from the Catholic Church, I find myself using Christian language. At the end of the day, I don't care what theists think about my beliefs.
