Since I got nothing else but my own realization of irony, best to post that.
Oh, and when I say "you" I speak to whoever cares to think I'm talking to them, not like I'm pointing anyone out. Just trying to explain how I can..
2. Reason (apologetics)
3. Revelation (mystical or semi-mystical experience)
Ok, I found it somewhat ironic that to be a "true believer" you only become completely oblivious to logicality and end up following anything that you want. (nothing wrong with that, but it seems a bit off without any proof to rationalize it all)
Faith: belief without proof. Now, if you need "faith" to be a "true believer" you'll be believing completely out of your own opinion. There is no proof that your belief is correct and when you have faith in it, you won't have any real logical explaination other than "I have no proof, but I believe." I can see why this works, but still; it appears a bit off.
Reason: (there are many defintions, I'll use this one for now) A premise, usually the minor premise, of an argument. Somehow, you can have "reason" in a belief of something that cannot be proven? To create a reasonable explaination of this belief you have would only belief without proof. You would be using "reasoning" to explain how something exists that is not provable to exist? That isn't quite rational. If you're going to be a "true believer" the only reasoning you have is circular because nothing can be proven. That will make you a "true believer" albeit an irrational sounding one.
Revelation: (here's something) Something revealed, especially a dramatic disclosure of something not previously known or realized. Ok, if you've discovered something or had something happen to make you believe something new, then it should be easily explainable or at least somewhat believable, or else "how would you, yourself, believe it?" When you have that "eureka moment" and realize something is real and it had not been apparent to you before, you've just established that anything else you did know is incorrect. You've found something new and remarkable that affrims your beliefs and makes it all make sense to you. You've had a revelation and are now able to be a "true believer" because you have actually created your own truths in the process. Figuring something out that has not been previously known by you, but not having any explaination or proof of it makes it basically a silly following.
I felt I should chime in on this since I'm new and haven't seen anything else that I actually know about. (hehe) Still reading over everything around here, nice concept.
