"I have written something to the church, but Diotrephes, who likes to put himself first, does not acknowledge our authority. So if I come, I will bring up what he is doing, talking wicked nonsense against us. And not content with that, he refuses to welcome the brothers, and also stops those who want to and puts them out of the church."Over time a clique developed and only those core members supporting his inerrant opinions were considered truly Christian. Many members left disenchanted, others were withdrawn from, and sent scurrying down the road. After about ten years only 50-60 hard core members that are completely in subjection to his leadership remain at this location.3 John 9, 10 (ESV)
This church will not work with--and in many cases not recognize--other Churches of Christ in the area, because in his eyes all other COC groups have gone astray, and are no longer a part of the Lord's church. This preacher (?) goes beyond the precept that only COC groups are members of Christ's body; only his church, and those believing exactly like him are acceptable to the Lord.
Men who demand total control of a church, and refuse to work in tandem with other members will destroy that church. They will not tolerate any opinions other than their own perfect understanding of God's Word, and will fight to the bitter end to uphold their self-appointed position against all comers.
