Same authority has been given to every believer in Christ.
By Matthew 16:18-19
Then why do all these protestant churches elect leaders to be spokesman for their church? Where in the Bible does it say that there's a "Office of the President of the Southern Baptist Convention". Did Jesus give Bryant Wright that authority? Seems pretty "unbiblical" to me. If they believe in the "same authority of all believers", then all 16.7 million members of the SBC ought to be voting on what their denomination says, not this guy.
