Lass o' the Glen, thank you so much for your words of encouragement. A couple years ago, when we were having a not-so-pleasant phone conversation, she stated, "I'm not in a cult." I had not said anything about her being in a cult at that time, and I really didn't think she was then, but I could tell that GCC was having an affect on her views. Is it the right thing to do to confront her about being in a cult, or is this a thing that would cause a MacArthurite to be even more intransigent? She has a naturally inquisitive mind and does tend to look things up to get more educated on things.
I am indeed praying for her daily. I have found it difficult in the last few weeks to contact her at all, as it always deteriorates into a criticism/judgment/condemnation session. which I don't want to be a part of. I am praying Isaiah 49:25 over the situation. "I will contend with him that contends with you, and I will save your children."
I would strongly recommend you don't accuse it of being a cult when confronting her. In my experience, when they are confronted with GCC being a cult they usually will block out anything else that is said. Remember that when they have accepted Lordship Salvation they believe all of Christianity is teaching a watered-down salvation, and the second you refer to them as a cult you are dumped into the "non-lordship" category, and no matter what you say it will be disregarded.
If there were a way you could show the similarities between GCC and Scientology, the flaws in the Restoration Process & Counseling doctrines, how the counseling has failed to cure mental illnesses, why other theologians have rejected Lordship Salvation, MacArthur's denial of the atonement of Christ, MacArthur's acceptance of some Calvinistic doctrines and the fact that Calvin was a murderer, etc.
Remember many who get caught up in this cult have not been exposed to any Christianity in the past. Also, it is a very slow mind-control process that they use. The whole thing is not revealed up-front, or people wouldn't join. At first they start by using buzzwords from mainstream Christianity like grace, eternal security, etc. Remember your daughter may not have been exposed to the whole thing yet and she may later realize that it is not what it initially appeared to be. See if she knows why MacArthur opposes Catholocism, what the full implications of end-times conspiracy theories are, and how that affects your salvation in light of the Bible verses mentioned. Why should you have to repent or receive counseling because you work for Catholics? If you are eternally secure why should you have to go through a restoration process to get God to recognize you as a believer and not turn His back on you?
These are things that could potentially get her to start doubting MacArthur. Make no mistake about it, it is definitely a cult. It is designed to eventually get you to give up all your money and time and become a total slave. Members join under high pressure tactics, get others to join, use confrontation to pressure people that have to be "restored," sign up for expensive classes to get degrees to spread the doctrines to get other to join. It is a vicious cycle that needs to be stopped.
