That's a good description, Hitch! As a former Charismatic, I testify to the way that definitions are simply changed (without saying so up front) so that their teachings sound orthodox while being nothing close to orthodoxy at all.

In my Charismatic days, faith was "that force which is present in all humans whether regenerate or not, that can be called upon and put to use by means of the spoken word, both for good or for evil." Hardly a biblical definition at all, yet the way the term was applied, that was the only possible meaning!

The FV folks do the same thing with terms like justification, imputation, covenant, and church.
