The Bible emphasizes that we must be united as one body, have the mind of Christ, and be unanimous as the early church was.
11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
1 Corinthians 12:11-13
The reality is that our goal should not be that we be one body, but that we must already be one body in Christ Jesus, to recognize and live this great reality of the church of Jesus.
