I agree with
@Scarlett O. in post #2.
I think the Lord sometimes overrules disagreements among Christians for His own sovereign purposes.
There was a church in Cardiff, Wales where they had had one Pastor for around 50 years. Toward the end of his time there, he brought his son in as 'assistant to the Pastor' with a view to his taking over when he retired.
However, the elders and the majority of the congregation took a different view and appointed someone else to the post when the Pastor finally retired. But about 50 members of the congregation left the church and set up a new one with the Pastor's son as the minister.
While this is all regrettable in many ways, the result is that there are now two fine Bible-believing churches where there was formerly one. I don't know the situation well enough to say if they are now fully reconciled or not, but I believe God has used an unfortunate situation for His glory.
[N.B. I am not saying that there are only two Bible-believing churches in Cardiff. PTL, there are many more than that, but there is one more than there used to be]
