I spent about 3 years listening to weekly "The Bible Answerman" programs from Walter Martin when I lived in S. CA. It gave me an amazingly good insight into the cults, right after I had extracted myself from the Local Church.
The Local Church is not its actual name--Witness Lee, a Chinese gentleman, who escaped Communism in China, founded a denomination that he actually denied was a denomination. He in fact disowned any name for his denomination whatsoever, calling his following the "church in Anaheim," the "church in Las Vegas, " the "church in New York," etc. He thought the church should not have a name and should be one in each city, excluding all denominations.
I got into the group because I had been a student of Watchman Nee, and knew that Witness Lee had been his associate in China. What I didn't know is that Lee had changed from Nee, and had indeed started a new cult!
Walter Martin's organization, Christian Research Institute, sponsored a pamphlet by the Passantinos, who exposed it as a cult. I read it and responded, angrily, by letter to Dr. Walter Martin in 10 pages! Then I proceeded to move from the Pacific NW, due to it raining on my motorcycle relentlessly, and find a home in S. California, close to where Lee ministered and where Stream Ministries was located. Stream was the publishing outfit that published books by both Watchman Nee and Witness Lee.
I chose to live in Anaheim because that's where this "Local Church" was based. But I after a few months became convinced myself that it was indeed a cult. They thought of themselves as superior. Martin's group pointed out that they were modalistic in their theology. Another group, Spiritual Counterfeits Project, out of Berkeley, claimed they were "non-Christian," for which SCP was successfully sued.
So yes, they are Christian, but yes, they are also a cult. To my disappointment, a few years back I heard from Gretchen Passantino, the one who had written that tract against Lee's group for CRI. She and the successor to the Bible Answerman, Hank Hanegraaff had decided the "Local Church" was no longer a cult!
We were emailing about this when she stopped writing. I later saw in the news Gretchen died! So I never got the whole scoop. But I'm absolutely convinced that even though the cult has stopped being modalistic in their theology, they are still a cult! They are still eccentric and elitist. They have a strange spirit, coupled together with any possible genuine spirituality.
This is just a human interest story, but it shows I have a personal interest in cultic thinking. And I empathize with Paul in his concern to deal with a cultic group *within Christianity* that was making a pretty outlandish claim.
But then again, take a look at what Democrats ran on in the last election and won!! Open the borders to the contagious, the terrorists, the gangs. Spend money in the trillions to make future generations laden with debt. Kill our energy industries, except the ones that don't work long term so we are slaves to the Middle East and to Russia.
Outlandish statements can always be rationalized away! See Biden.
