This is axiomatically correct. And there are religious traditions (particularly eastern ones) where doubt is the path. Total doubt, not just of religion, not just of atheism, but of everything. Doubt of the “I” that pops up in your mind out of habit. Doubt of words that one uses to name one’s feelings.

There is nothing “wrong” with believing the Bible. There is nothing right about it. It’s just another belief that is also subject to doubt.

We don’t know shit. And we don’t even know that we don’t know shit. Doubt that too.
