The Authority of the Holy Scriptures

(Excerpts from Francis Turretin, simplified)

1. What We Mean by the Authority of Scripture

The authority of Scripture means that the Bible has the right to command our faith and obedience. When Scripture speaks, God Himself speaks. Therefore, the Bible is not merely helpful advice, but binding truth.

“All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness.”
— 2 Timothy 3:16

Scripture does not borrow its authority from the church, scholars, or human approval. It has authority because it comes from God.

2. Scripture’s Authority Comes from God Alone

Francis Turretin strongly taught that the Bible’s authority is intrinsic, not borrowed.

• Scripture is authoritative because God is its author

• God is truth itself and cannot lie

• Therefore, His Word must be true and authoritative

“The word of the Lord proves true.”
— Psalm 18:30

Just as a king’s decree has authority because it comes from the king, so Scripture has authority because it comes from the King of heaven.

3. The Church Does Not Create Scripture’s Authority

The church does not give authority to the Bible. Rather, the church recognizes the authority already present.

Turretin carefully distinguished between:

• Authority itself (which belongs to Scripture alone)

• Recognition of that authority (which the church provides)

“The church is built on the foundation of the apostles and prophets.”
— Ephesians 2:20

The foundation supports the building, not the other way around. The Bible stands above the church, not beneath it.

4. Scripture Is Self-Authenticating

Turretin taught that Scripture carries clear marks of its divine origin. These include:

• Its holiness and purity

• Its harmony and consistency

• Its power to convict, convert, and comfort

• Its fulfillment of prophecy

• Its majesty and simplicity combined

“The law of the Lord is perfect, reviving the soul.”
— Psalm 19:7

Just as light proves itself by shining, Scripture proves itself by its divine power and truth.

5. The Role of the Holy Spirit

Although Scripture is objectively authoritative, we are blind without the Spirit. Therefore, the Holy Spirit inwardly persuades believers that Scripture is God’s Word.

“My sheep hear my voice.”
— John 10:27

This inward witness of the Spirit:

• Does not add new revelation

• Does not replace Scripture

• Confirms Scripture’s authority to the heart

The Spirit opens our eyes to see what is already true.

6. Scripture Is the Supreme Judge in All Matters of Faith

Because Scripture comes from God, it is the highest court of appeal.

• Traditions must be tested by Scripture

• Councils may err

• Teachers may fail

• Scripture alone is infallible

“To the law and to the testimony! If they do not speak according to this word, it is because they have no dawn.”
— Isaiah 8:20

Nothing stands above the Word of God—not reason, not experience, not church authority.

7. Our Duty Toward Scripture

If Scripture is truly authoritative, then our response must be:

• Faith – believing what God has spoken

• Submission – obeying even when it corrects us

• Reverence – handling it with fear and humility

• Diligence – reading, hearing, and meditating on it

“If you love me, you will keep my commandments.”
— John 14:15

To reject Scripture is to reject God Himself.

8. Summary in Simple Words

Francis Turretin teaches us this:

• The Bible is authoritative because God wrote it

• The church does not give the Bible authority—it recognizes it

• Scripture proves itself by its divine qualities

• The Holy Spirit convinces believers of its truth

• Scripture alone is the final judge of faith and life

Where Scripture speaks, God speaks.
Where Scripture commands, we must obey.
