Many people in positions of teaching others the doctrine of their particular religion do not actually believe the doctrine themselves. This is a fascinating article from Daniel Dennett and Linda LaScola. I could relate to some of the expressions made.
One preacher quoted in the article:
"Even if Christianity isn’t true, is it best to leave the people alone in their ignorance? And I struggle with that feeling of superiority intellectually, which I’ve read all kinds of faith literature, and they say that’s just a struggle you’ve got to deal with. But is it better to leave them ---? And they’re happy, and they have hope in a life to come, and so it helps them through their suffering, which is a strong selling point of Christianity. You know what I’m saying? I look at things a lot more in kind of a marketing form now."
Meanwhile, he struggles through his job, hiding his beliefs.
"Here’s how I’m handling my job on Sunday mornings: I see it as play acting. I kind of see myself as taking on a role of a believer in a worship service, and performing. Because I know what to say. I know how to pray publicly. I can lead singing. I love singing. I don’t believe what I’m saying anymore in some of these songs. But I see it as taking on the role and performing. Maybe that’s what it takes for me to get myself through this, but that’s what I’m doing."
