This is Part #3b on my series about the absolute sufficiency of the Scriptures as the sole, infallible authority for Christian faith and life. Part #1 set the stage. Parts #2a and #2b examined what several books in the New Testament had to say on the subject. Part #3a, along with this post, examine several critical passages which teach the doctrine of sola scriptura.
2 Peter 1:16-21
In this passage, Peter shows great concern that Christians “confirm their calling and election,” (2 Pet 1:10). He listed several traits (2 Pet 1:5-7) which should be the practical outworking of a fruitful life in Christ (2 Pet 1:8). Peter endeavored to constantly remind Christians of these points (2 Pet 1:12-15), and then set out to demonstrate the validity of the truth he preached.
Peter made it very clear that he and the other apostles “did not follow cleverly devised myths” when they preached of the second coming of Christ, and reminded his readers he was an eyewitness of His majesty! (2 Pet 1:16). Once again, deviation from a concrete, propositional truth is a negative thing to the NT evangelists. Peter is stressing the legitimacy of the doctrine he preached, and he did so by affirming that it was truthful and in accordance with actual events. Peter recounted what he saw on the Mount of Transfiguration, when he saw the glorified Christ and heard the voice of God the Father issuing His seal of approval on His Son’s ministry. His Second Coming will happen. Peter assures his audience he knows this to be true because he witnessed God’s approval on His Son (2 Pet 1:18).
Implicitly, then, the whole of the Gospel message is also true and correct. Peter makes this very connection when he remarks, “and we have the prophetic word more fully confirmed,” (2 Pet 1:19a). Peter’s eyewitness testimony confirms the validity, accuracy and above all the sufficiency of the OT Scriptures – the transfiguration confirms the eventual fulfillment of the prophesies. Peter uses the authority of the OT Scriptures alone to confirm the new mystery of the church age and the Gospel of Christ. This is progressive revelation once again; the new revelation in perfect accord with the old.
Meanwhile, as Christians wait for that blessed day (Titus 2:13), Peter calls his readers back to the sacred Scriptures, encompassing both the Hebrew Scriptures and the new revelation of the apostles. He tells them to “pay attention” to them, “as to a lamp shining in a dark place, until the day dawns and the morning star arises in your hearts,” (2 Pet 1:19b). “As a light, God’s word has validity and authority.”
It is significant that Peter directs his readers only to God’s unshakable word for comfort and guidance in Christian life. Calvin remarked,
His object only was to teach us that the whole course of our life ought to be guided by God’s word; for otherwise we must be involved on every side in the darkness of ignorance; and the Lord does not shine on us, except when we take his word as our light.
Peter continued onward and emphasized the source of Scripture; “no prophesy of Scripture comes from someone’s own interpretation,” (2 Pet 1:20). Again, it is not a cunningly devised fable. It is divinely inspired. It is propositional truth. No true prophesy “was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit,” (2 Pet 1:21). “To bear” or “to guide” translates the Greek word phero. As Scripture authors penned their works, they were impelled, borne along and guided by the Spirit. “The metaphor here is of Prophets raising their sails, the Holy Spirit filling them and carrying their craft along in the direction He wished.” This, along with 2 Tim 3:16-17, is clear testimony to the divine nature, authority and absolute sufficiency of the Scriptures.
