One of the statements that I have always made and the book by David Cloud that I am linking to back it up is that those who sit in fundamentalist pews are usually the most biblically ignorant among all Christians. This is due in large part to the cult mentality that they typically share. It expresses itself in KJV Onlyism and man worship among other things.
What is sad is that many of the people like Hyles and others are followed almost blindly and even have excuses made for them, but if you are a genuine Pastor out there attempting to teach and instruct your congregation to study the Bible for themselves and don't happen to use the KJV; well you are cast out, excommunicated, and cast off as a blasphemous heretic.
Further, what is sad is that most people today have no clue how brainwashed they truly are. That is ultimately the success or failure of a cult in that how many can they brainwash into blindly following and obeying their every word and demand without a second thought of whether or not they should. What is the ultimate in cult like fundamentalism is when you can convince a large group of people to defend you even when you have engaged in gross sin.
I think there were many that got caught up in a lot of this and were at best naive. Had they known better many would have ran away as fast as they could have. Sadly, there are those to this day that will toe the fundamentalist line even if it means casting off their own family members; even their family members in the Pastoral ministry; albeit not fundamentalist pastoral ministry.
I simply refuse to do anything because some man said so, but rather I will operate under the clear teachings of Scripture, and instead of man worship, I will engage in Christ worship. Instead of engaging in radical Onlyism, I will teach my congregants to study the Bible as much as they can, in the original languages, and in its full context.
One of the best things that Cloud's book brings out is that for Hyles and many fundamentalist preachers they only use the Bible for their pretext or jumping off point and then from that point you can just shut up your Bible and simply listen to the man instruct you as to how you can please him better.
So take some time and read through both of these as they are related. I hope you will reach out to anyone you know caught up in this and help them escape this mentality.
