1 Corinthians 1:10  Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.

The Holy Ghost through Paul is encouraging us to speak the same thing meaning we should all believe the same doctrine. It would be difficult to remain in fellowship with a brother or sister who didn't believe that same as you do. We should all agree  on the King James as the Bible which God uses and the only one in English and in any other language for that matter. So doctrinally we should all be on the same page.  There should be no divisions ( splits, schisms). among us.  If we are all saying and believing the same teachings out of the King James Bible there wont be any room for division or confusion.
