This is the fundamental belief among most if not all Christian denominations. Of course there are some minor specifications that vary but in general it goes something like this:

People who don't accept Jesus Christ as atonement for their
sin go to hell.

For those who don't know. (http://en.wikipedia.org/wiki/Argumentum_ad_baculum)

I'm having trouble determining what words express my question clearly but here it is:

Does the possibility(because I'm not entirely sure if it is really a logical fallacy) that it is a logical fallacy, render it invalid? If so does it render other beliefs founded upon it invalid?

The possibility that something is a logical fallacy is meaningless. You must conclude that something is probable before effectively convincing anyone of something. It's possible that I'm going to give you a million dollars tomorrow. For you to convince a reasonable person that I will, you're going to have to produce some convincing evidence.

Still unclear. Are you saying that in order to convince anyone that this belief is irrational I need to provide evidence?

Of course.

Where did you get the idea that if it's possible something is invalid then it is invalid?

Of course.

Ok gotcha.
