Going KJO significantly pushes an IFB toward cultism. Since KJO tend to break fellowship with those who don't agree it moves them toward being part of the "exclusive" true believers. Also it opens the door to follow man centered traditionalism much like the Catholics.That is a really odd list. See response:
1. KJO does not a cult make. It may become heretical in some churches (only saved by KJV), but a little heresy isn't a cult, it is incorrect teaching.
2. Nowhere near Amish standards. They only want women in dresses and not low cut tops. Plenty of very modern attire. Much of the modern dresses are, however, very flattering to form. Wearing a dress doesn't promote rape - that is just weird.
3. I have been in most of the dominant IFB churches over the past 40 years. I have never heard anyone wish to ban holidays.
4. Bill Gothard? Not really who I think of with IFB, but, whatever.
5. yeah, agreed.
6. Scofield as authoritarian text? I could see if you put the teachings of Hyles, Rice, etc. Most IFB have no commentaries other than sermon tapes from JH and don't read any other writers.
The first IFB I attended years before I settled in an IFB held no affinity for Christmas. In this particular church the sr. pastor was always happy and positive and an older assistant pastor was the guy to bring out the wrath. I remember him coming out and talking about there being nothing significant about Christmas and for him and his family it was just another day. Talked about how December was even the wrong time of the year for Christ's birth and that if we were meant to celebrate it then God would have provided the date in His Word. I think it's a minority of IFBs that reject the celebration of holidays but they still exist.
