But..Here Is Where People Question And Start Asking Again..
What IsThe church of Christ? 
Again, It's Christ's, The Saved, His Body Of Believers,
Those Souls God Ads To The Body When The Gospel Is Obeyed.
So, Shouldn't The Question Be.. How Does One Become A Part Of The church of Christ,
Rather Than Again, Asking And Getting Caught Up In What Is The church of Christ?
Again, Concentrate On How, Not What..
That question was asked in the first century as it is asked today, and the answer remains the same.
We are saved and added to the Lord’s church when we obey the gospel of Jesus Christ.
Like the Apostle Paul, we are saved when our sins are washed away at our baptism.
So, In Summary..
There is one church of Christ.
If you are a member of something else or something more or something less, then you are not serving God according to His plan or according to His will.
He wants you to be a Christian and only a Christian, wearing only the name of His Son,
Jesus Christ, who is the head and the savior of the church, His body.
