One City One Church, any of the Church Fathers Practice it?

I think many members of the LC didn't use their brain enough when they're taught of certain doctrine. I no longer see the one city one church as truth when I use my basic logic. I accepted it back then not because I was convinced but because I was taught like that, that's what I know about Christianity from a non Christian background. Think about it, how many scholar or believers in this world? They don't see the ground of oneness yet watchman saw it, the Lord have revealed to him. How strange, sounds like Joseph Smith experience?

The LC are locked within their own thing, since they're so proud of themselves, it's a closed and self serving system. They say they practice open fellowship, says if 10 brothers gatherd, they will make a conclusion or agreement by majority vote, but obviously they're not open up that fellowship to the rest of the body. Their oneness is practiced within themselves, strange nobody raise the issue. Because I think no one dare to raise the issue, otherwise you'll be quarantine for speaking the truth or be label as rebellion. How does this kind of environment is encouraging? The damage done to the people within is not a small matter. It fooled people and caused them to lost the blessing from being able to love other Christian who's not in their group.
