Further on it mentions that he removed himself from the shepherding group and publicly repented of his involvement in it.....
CGM’s strong emphasis on submission was controversial. Lydia Prince herself disapproved, and as stories of abuses came out the movement was condemned by Pat Robertson, Kathryn Kuhlman, and the Full Gospel Business Men's Fellowship International. Most of the opposition to these teaching came from those who heard of the abuses yet never studied the actual teachings. Many leaders eventually reversed their position (e.g.; Bill Britton Ministries). Lydia died in 1975, and when Prince later wanted to marry Ruth Baker, his fellow shepherds prayed about it, and each of them initially felt it was not God's will. Derek chose to submit to their discernment. A very short time later each of the men said God made it clear to them it was His will, and Prince was re-married in 1978. Derek believed this was a test by God to see if he would live what he taught. Derek was the elder statesman of the group and lived by the principles he taught. Nowhere in any of his teaching on submission and authority does it suggest any person has the authority to demand submission. Nor does it suggest that those in authority make decisions for those under authority. The fact that these teachings were perverted and used by the immature and unscrupulous is something seen in every facet of human endeavor.
Derek later left the group and repented in public over being a member of this group.[21] There are several sermons where Derek commented on the shepherding controversy (sometimes referring to it as "discipleship movement").,[22] even in Ft. Lauderdale years after.[23]
One thing we always need to keep in mind and be on the alert for is that Satan works to get people to deny Christ on the one side and on the other to corrupt the teachings if they do believe. We can take on faith what Jesus said but not what man teaches. We need to be very careful to “test the spirit”.
1 John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Given the amount of false doctrine out there the words of Paul to “search the scriptures daily” is of vital importance.
It’s interesting that your post mentions Kathryn Kuhlman. It was she that most influenced Benny Hinn after he went to her meetings in Jerusalem in 1974. There is a very good article about her here: http://www.deceptioninthechurch.com/kuhlman.htm that looks to be done in an honest way. That site also has many other articles about deception in the church that may be of interest. I have not read them all so make no claims about them one way or the other.
