- Dogma - something essential to the faith. Denying this is in essence excluding yourself from the classification of "Christ-followers."
- Doctrine - something important to a specific group of believers (church, denomination, etc.) but not essential to the faith. Significant disagreement here might mean you'd be better off with a different group of worshipers, but doesn't mean you're not a Christian.
- Opinion - something of interest to you, but definitely not worth dying for.
If you're a part of that group (or are interested in theology and want to enter the conversation), use the comments feature of this blog to facilitate interaction. I'm looking forward to learning with you!
