I don't have time to explain the whole story of where your definition came from, but I will just say:n
1. It's not a theological definition, but a popular one.
2. It is not accepted by fundamentalists, and we consider it to be pejorative. It is usually a way to insult fundamentalists, so I'm disappointed you are using it. You usually impress me with your posts.
3. It did not exist until the New Evangelicals started their movement in the 1940's and 1950's. Until then, everybody in evangelicalism believed in honoring God with their standards. Many were even against things we modern fundamentalists believe to be okay: the theater (for plays, not movies), etc.
4. If you think it's fine to go to church without a suit, or women wearing pants, etc., fine, but that is not what evangelicalism used to be. It's an invention of the New Evangelicals. At our church, anyone can wear almost anything, but they gradually learn what we believe honors God.
That's all I'll say. I'm away from home at the Bible Faculty Summit, or I could give plenty of evidence in the form of historical events, quotes, and the like.
You are obviously convinced of your position and willing to call me a legalist, so I'll bow out now.
