What sources could one appeal to if trying to argue if a doctrine was or was not consistent with fundamentalism?
The question What is fundamentalism? identifies the historical source and some of the main characteristics of fundamentalism. I am more interested in the current usage of the word an identifying when to label something as fundamentalist and when to use a different label.
There seems to be a lot of overlap beftween the scope of fundamentalist and that of other labels. The media these days bandies the word around* in a way that is generally derogitory, but it isn't exactly clear why. Sometimes it seem to refer to a very specific group as if it were a denomination. Other times it seems to mean just a general theological bent. One minute it is used to pigeon hole far out groups like Westboro Baptist Church, other times it seems to encompass most of mainstream Christianity.
Hoes does this wide ranging usage affect how Christians use the word for themselves? Particularly among those who take this label on themselves, do they refer to any authority or standard in order to do so? Is there an official authority on when one is a fundamentalist and not just somebody who holds most of the same beliefs?
For example, in the Reformed tradition there are specific creeds such as the Westminster Confession of Faith, and identifying yourself as Reformed is commonly understood to that place you somewhere close to to these creeds. What sources would a fundamentalist turn to to show that their beliefs were or were not consistent with the way they label themselves?
* "Evangelical" and "conservative" are viable contenders in the race for meaningless labels.
