“On the Legitimacy of Evangelical Churches
and Denominations”
We believe, as do most Christians, that the Body of Christ is uniquely and universally one (1 Cor. 1:12-13; Eph. 4:4; Col. 3:15). We also believe that the Lord’s desire is for the practical local expression of His Body to be locally one. In fact, the divine oneness of His believers practically is among the things He died to accomplish
(John 17:21; Eph. 2:14-15). The implication of this basic understanding is far reaching. It means that we must receive all genuine believers in the common fellowship of the Body of Christ (Rom. 15:7; 1 Cor. 1:9).
Romans 15:7 is very important to the nature of a local church. In principle it must receive all whom Christ has received. The very word
church stands against the thought of divisions and denominated believers according to something other then where they live.
I wrote above that if any church I participated in made the reading of books by Witness Lee a requirement of being received, I would not recognize that gathering as true local church. There is a need for repentance and recovery in that case.
For Paul's instruction is to receive as brothers and sisters all those whom we can discern have been received by Christ Himself. And that is all kinds of believers.
"Therefore receive one another, as Christ also received you to the glory of God." (Rom. 15;7)
Take the creator of the critical video, Brent Barber. Now, all the local churches I have ever met with would receive this man
IF he wants to be received. He may not like messages by Witness Lee. But if he belongs to the Lord, to cut him off is to cut off ourselves. He is a member of the Body of Christ.
Now if Brent Barber doesn't want to participate in the oneness on the local ground for some reason, he has the freedom of conscience to not meet on that ground. He may choose a denominational ground.
The fault of division is not on the local church. The preference to meet in division is Brent's decision.
The Lord said where ever two or three are gathered into His name, there He is in the midst. So the gracious Lord is faithful to give His presence where ever Christians meet in His name.
However the Lord did not say that every gathering of two or three is a church. Otherwise Jerusalem, where they gathered from house to house in probably hundreds of homes in that locality would have had hundreds of churches.
You can never find the mention of churches [plural] in Jerusalem in the New Testament. You can never find the mention of more than one church in ANY locality in the New Testament.
Having said that, neither should Brent make an issue of saints on the local ground who DO feel enthusiastic about following the ministry of Lee and Nee. Both kinds of saints should mature and be accepting of each other in love. He cannot say Christ has not received them who like Lee's books. They cannot say Christ has not received Brent who has become suspicious of those books.
