Were the Apostles’ Doctrines Shaped by Their Fallen Nature?

Question 01004.

The question of scriptural reliability becomes very pointed when we ask whether the apostles’ fallen nature corrupted the doctrines they taught. It is a fair thing to wonder. Peter, Paul, John and the rest were sinners like us. Paul had been a Pharisee. Peter was impulsive and once had to be rebuked to his face. If sinful men wrote the Bible, did their sin seep into the text and distort the truth? On the answer to that hangs a great deal, because if the apostles’ flaws compromised their teaching, then scriptural reliability collapses and we are left guessing which bits to trust.

I want to take the worry seriously rather than wave it away, because it touches the foundation of everything else we believe. So let me set out why the fallen nature of the human authors does not undermine the scriptural reliability of what they wrote.

What the question really asks

At root this is a question about how inspiration works. Nobody denies that the apostles were sinners. The real issue is whether God was able to use sinful men to produce a text that is nonetheless His own true word. If inspiration depended on the moral perfection of the writers, we would indeed be in trouble, because there were no perfect writers. But Scripture never claims that its authors were sinless. It claims that God so superintended their writing that what they produced was exactly what He intended.

That is the doctrine of inspiration, and it is the hinge on which scriptural reliability turns. The classic text is 2 Timothy 3:16, where Paul says all Scripture is breathed out by God. The Greek word is theopneustos, God breathed, and it locates the origin of Scripture in God rather than in the unaided minds of men. I have written more on this term in my article on what God breathed means.

How God secured scriptural reliability through sinners

The clearest description of the process is in 2 Peter 1:21: no prophecy was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit. The picture is of a ship carried by the wind. The human authors were genuinely active, using their own vocabulary, personality and style, yet they were borne along by the Spirit so that the result was God’s word and not only theirs. That is how scriptural reliability survives the fallenness of the writers.

Notice that this does not turn the apostles into typewriters. Paul still sounds like Paul, John still sounds like John, and their distinct voices come through on every page. The Spirit did not bypass their humanity, He sanctified the use of it, ensuring that what they freely wrote was at the same time precisely what God willed to be written. Their fallen nature was overruled, not given free rein.

Jesus and the apostles on scriptural reliability

It is worth remembering that Jesus Himself authorised the apostolic witness in advance. In John 16:13 He promised that the Spirit of truth would guide them into all the truth, and in John 14:26 that the Spirit would bring His teaching to their remembrance. So the writing of the New Testament was not a group of fallible men doing their best from memory. It was the fulfilment of a specific promise that the Spirit would secure the accuracy of their testimony.

Jesus also treated the Old Testament, written by equally fallen men, as utterly trustworthy, down to its smallest details. He said Scripture cannot be broken in John 10:35. If the sinfulness of human authors had compromised the text, Jesus did not seem to know about it, and His confidence in scriptural reliability ought to settle the matter for those who follow Him.

Does the Bible’s honesty about sin help here?

One thing that quietly strengthens the case for scriptural reliability is how unflinchingly the Bible records the failures of its own heroes and authors. If sinful men had shaped the text to flatter themselves, we would expect their flaws to be airbrushed out. Instead we read of Peter’s denial, of Paul’s past as a persecutor, of David’s adultery and the patriarchs’ deceit. This is not the work of men managing their reputation. It is the mark of a text governed by a higher hand committed to the truth.

The candour cuts the other way from the objection. Far from their fallen nature corrupting the record, the writers were carried along to tell the truth even when the truth condemned them. That is exactly what we would expect if God, and not human vanity, was directing the project.

Why scriptural reliability matters so much

This is not an abstract debate. If the apostles’ sin had infected their doctrine, you could never know whether any given teaching was God’s truth or only Paul’s prejudice, and the whole house of faith would rest on sand. Scriptural reliability is what allows us to take the Bible’s teaching about salvation, about Jesus, about eternity, as the reliable word of God rather than the fallible opinion of ancient men. Everything else depends on it, which is why I treat the trustworthiness of Scripture as the ground I stand on, as I explain in my piece on what infallible means.

So the fallenness of the writers, far from being a problem, actually magnifies the wonder of what God has done. He took sinful men, did not pretend they were anything other than sinners, and yet through them gave us a perfectly trustworthy word. That is the same pattern by which He saves and uses any of us.

Scriptural reliability and the manuscript evidence

Some who worry about the apostles’ fallen nature are really worrying about a related question, namely whether the text has been faithfully preserved across the centuries. It is one thing to say that God inspired the originals, and another to ask whether what we hold today reflects them. Here the evidence is genuinely reassuring. The New Testament is preserved in thousands of manuscripts, far more than any other document of the ancient world, and the agreement among them is remarkably high, so that scriptural reliability is well supported on historical as well as theological grounds.

Where variations between manuscripts exist, they are overwhelmingly minor matters of spelling and word order, and none of them unsettles a single doctrine of the faith. The God who inspired the apostles also providentially preserved their writings, so that the church across the ages has had access to a trustworthy text. I have written more about the textual questions and the claims of the King James Only movement in my article on KJV Onlyism, but the short answer is that scriptural reliability does not hang by a thread.

This matters because the objection about the apostles’ sin and the objection about manuscript transmission often travel together in the mind of a doubter. Both ultimately ask the same thing, can I really trust this book. The biblical answer ties scriptural reliability to the character and providence of God at every stage, from the inspiration of the writers to the preservation of their words, so that the Bible you hold is not a corrupted relic but the reliable word of the God who has guarded it.

What this means for the doubting believer

I have sat with Christians whose confidence in the Bible was quietly draining away because someone had planted the thought that it is, after all, just a human book written by flawed men. The doctrine of inspiration speaks directly to that fear. Yes, the writers were flawed, and Scripture never hides it, yet God carried them along so that what they wrote was His own word. Your faith does not rest on the unlikely hope that ancient men happened to get everything right. It rests on the God who guaranteed that they would.

That truth is meant to be more than a debating point. It is meant to send you back to your Bible with confidence, reading it as the voice of God rather than the opinions of men. When a passage searches your conscience or makes a demand you would rather avoid, you cannot dismiss it as one writer’s personal bias. And when a promise seems too good to believe, you can lean your whole weight on it, because the same God who inspired the words stands behind every one of them.

So, now what?

Let this steady your confidence the next time someone suggests the Bible is just the religious opinions of flawed men. It was written by flawed men, yes, but it was breathed out by God, who carried them along so that scriptural reliability rests on His character rather than theirs. You are not trusting Peter’s good judgement or Paul’s self control. You are trusting the God who superintended every word.

So read your Bible as what it claims to be, the reliable word of God. Bring its teaching to bear on your life with confidence, not with the nagging suspicion that some sinful bias might have crept in. If God could keep His word pure through fallen men, can He not also be trusted to keep His promises to fallen people like you and me?

For no prophecy was ever produced by the will of man, but men spoke from God as they were carried along by the Holy Spirit.
