13.  We believe in the same church organization as existed in the time of Christ and his apostles. The highest office in the Church is that of an apostle, of whom there are twelve, who constitute special witnesses for Jesus Christ. They have the missionary supervision and the general watch care of all the churches.

Christ’s church has not changed. The organization that Christ left was the way he wanted it, so why would we want to change what Christ created. The apostles have the responsibility for the general watch care of the church as well of overseeing missionary work.  For further study read Mathew 10, Ephesians 4, Colossians 9:1, Mormon 9:18, Message 112:13.
