You fail to prove that any church is in unity! You are only fooling yourself if you think there is unity in most churches today! Why??? Because they have kicked out the apostles and prophets! Study what they did in the church and tell me we do not need them!
I don't have to prove anything about any church. If you have looked at my profile you would know that I go to an Independent Fundamental Baptist Church. Let me spell that out to you.
We are independent. That means we don't belong to any denomination, association, etc. We are completely independent of others.
We are fundamental. We hold to the fundamentals of the faith and are strongly opposed to all kinds of error such as the Charismatic movement and the ecumenical movement.
We are Baptist and hold to the historic Baptist distinctives.
As such we have a statement of faith that reflects all of the above.
We are united in our doctrine because we have been taught well.
Now, I know that any church that is Charismatic and believes the gifts are for today is bound to be confused in doctrine and a fairly chaotic church. They don't know where they are going or where they have been. So you probably don't know what a unified church is. That is what you seem to be saying.
But you don't have to deny my testimony in saying that we have a church that is unified in doctrine. In fact I know others that would give the same testimony. It is sad that you cannot.
