Christ Sent Me to Preach the Gospel ~ Not With Enticing Words!

Is Christ divided? Is the body of Christ to be made up of several groups or factions of believers within the larger gathering and assembly; should we, as a church be a diverse group of believers; all very different one from another, everyone doing their own thing and speaking differently one from another?
Or, should there be a oneness of mind and spirit within the church and a unity in the body of Christ?
