Continuing my above post. Years later I had the opportunity to talk with Bro. Jones about that very subject one on one. Let me just say that in my opinion he is one of the top three IFBx Kool Aid drinkers that I personally know. He let me know where the cow ate the cabbage on that topic in the way only Bro Jones could. Those in the bus ministry at WHBC know what I am talking about.
But I will say that I do not believe the IFB are a cult nor are the IFBxers a cult either in my opinion. I do believe they are extremely cultish in their behaviors. I believe they have many cultist tendencies and characteristics. But I do not know of any Cult that believes in the saving grace of our Lord Jesus and I do believe IFB are correct in that area as well as many others that would not classify them as a Cult.
Also, I will add, I see no Scriptural support for their position on many of the standards and rules they have adopted over the years. Therefore, as ExFundy said above, I believe they are definitely Legalistic but not a Cult.
