Are you sure? The following shows Scripture to be authoritative to teach, etc.:
2Tim 3:16 - "All Scripture is God-breathed (theo pneustos) and is useful for teaching, rebuking, correcting and training in righteousness,
so that the man of God may be thoroughly equipped for every good work."
"--and the Scripture cannot be broken--" (Jn 10:35)
Assigning authority over Scripture causes as much grievous error and damage as does anything else.
Are you familiar with its history of salvation by meritorious works, which is contrary to Paul in every way?
In both cases the "Scripture" being discussed would be the Old Testament, likely the Septuagint Version. When these words were penned the New Testament was in the beginning of its formation.
Be that as it may, teaching is a far cry difference from authoritative. For that matter neither is rebuking, correcting and training in righteousness authoritative. It is best described as charity, because clarity of the Word of God is charity.
The New Testament was written by the Apostles for the authority of the Church.
"The Bible is, and remains the Church's book, and the Bible can exist as Scripture only in the [Catholic] Church. Rahner [whom we've previously cited here] also maintains the Catholic insistence on Scripture and tradition as the bearers of revelation. Many recent Protestant authors have also faced up to the need to discuss the role of tradition, at least in the formation of the canon." Joseph T. Lienhard SJ, The Bible, the Church, and Authority,, p 84
Scripture, tradition and the Church co-exist and are co-authoritative. Without the Catholic Church to validate Scripture, Scripture loses authority to teach faith and morals. Scripture can never stand alone as the single and only source of God's word, as the sole purveyor of faith and morals. This freezes faith to a first century understanding which become unable to cope and grow with the current era. Simply, Sacred Scripture never makes the claim that it and it alone is the sole authority of faith. Scripture relies on the Church for its authentication. Equally important Sacred Scripture when defined as "the sole source" of God's words precludes miracles, prophecy, Church, and the doctrines of the ECFs. We know this not to be the case because the great and small saints of the Church are 'prophets of God'. Equally important is the Apostles weren't given a BOOK to worship, they were given a Kingdom to mend the fruits of His nation. It's within this Church that we find the Catholic Tradition the means of canonization (authentication) of Scripture. Our salvation would be ill advised to stop even at Tradition, rather we find 'Church' to be a part of a sole and infallible rule of faith. So we find the Apostles as authoritative witnesses wrote the Scriptures for the authority of the Church.
It is only in the Church that we hear the divine word taught divinely. I'll repeat, neither the bible, the Holy Spirit nor the Apostles would have infused "authority" in a BOOK. Had they done so, God's word would be mute once the Book is closed. If it did indeed have authority of this type, then every word, every phrase, every sentence would have been a clear as daylight and we could find (or not) our name in the list of saints.
Do you worship a book?
