Read it in its entire context. If you will look at the discussion that is provided by John Calvin on this passage in The Institutes of the Christian Religion you will discover that Augustine is not placing the Scriptures under the authority of the Church, as Mr. Matatics would have us to believe. Now, in just a few more seconds that is available to me, I want to bring up the issue of self-authentication. Mr. Matatics took on the issue of my statement that the Scriptures are self-authenticating. I want to point out again the vast chasm that separates us on this issue and how this demonstrates it.
Scripture is theopneustos.
It is God-breathed. God authenticates Himself. That is not the church of the New Testament. The Church of the New Testament is the Bride of Christ. She is obedient to the Word of God.
