Faithful creeds, confessions, and quotes are doing the same work a preacher does; they are explaining, illustrating, and applying the authoritative Word of God. The difference in Scripture and the preacher, the creed, the confession, Charles Spurgeon, John Calvin, John MacArthur, Steven Stanley, and John Fry is that we can err, and the Scripture does not.

The inspiration, inerrancy, and authority of the bible all relate to one another because they are all necessarily required and they all flow into one another.
