Fundamental Baptist who are separatists are accused of being divisive. Division by principle is always better than unity by compromise. Division caused by harsh words is unnecessary, but division caused by sound doctrine is necessary. It is not Bible doctrine that separates people, but their decision to obey or disobey it. If one person chooses to walk according to the course of this world while another chooses to be crucified unto the world in order to walk with Christ, their choices have divided them. This division is necessary, but dissension is not.
