Christians can read the same Bible, confess the same Jesus Christ, pray to the same Father, and sincerely desire to follow the Holy Spirit—and still disagree about doctrine. Sometimes those disagreements concern relatively minor matters. At other times they involve baptism, spiritual gifts, salvation, church government, prophecy, the Lord’s Supper, the relationship between Israel and the church, or the meaning of particular passages of Scripture. Some disagreements have lasted for centuries.
Why?
That question is worth investigating, but not because we need another doctrine explaining all the doctrines. Nor is the purpose of this investigation to suggest that doctrine does not matter. Scripture repeatedly demonstrates that what we teach and believe matters greatly. Neither should an examination of doctrinal disagreement become an excuse for saying that everyone is right, truth is relative, or theological differences are unimportant.
Another concern should remain with us throughout the investigation: love.
Jesus did not tell His disciples that the world would recognize them because they had resolved every theological disagreement. He said, “By this all will know that you are My disciples, if you have love for one another” (John 13:35, NKJV). That does not make truth unimportant. Jesus also spoke repeatedly about truth. But it does mean our pursuit and defense of truth cannot be separated from how we treat one another.
Perhaps, then, the first question should not be, “Which doctrine is right?” Perhaps we should begin one step earlier.
What does the Bible mean by doctrine?
What Is Doctrine?
The English word doctrine can sound rather formal. We may think of systematic theology, denominational statements, creeds, confessions, councils, or books containing carefully defined theological positions. Those things may contain doctrine, but the New Testament words translated doctrine begin with something considerably simpler.
Two important Greek words are διδαχή (didachē) and διδασκαλία (didaskalia). Both belong to the language of teaching and instruction. Their usages are not identical in every passage, but neither word inherently means an elaborate theological system.
After Jesus finished the Sermon on the Mount, the people “were astonished at His teaching” (Matthew 7:28). The NKJV uses teaching there for didachē. In Acts 2:42, the first believers “continued steadfastly in the apostles’ doctrine.” Again, the idea is what the apostles were teaching.
Paul uses didaskalia repeatedly in his letters to Timothy and Titus. It can describe good teaching or bad teaching depending upon what is being taught. That alone tells us something important: doctrine is not automatically trustworthy merely because someone calls it doctrine. The teaching must itself be examined.
Paul therefore instructs Timothy to remain in Ephesus so that he can charge certain people “that they teach no other doctrine” (First Timothy 1:3). A few verses later he speaks of teaching that is contrary to “sound doctrine” (First Timothy 1:10).
The expression translated sound doctrine is particularly revealing. Paul uses language of healthy, sound teaching. The Greek verb ὑγιαίνω (hygiainō) carries the idea of being healthy or sound. Paul is concerned with teaching that is spiritually healthy rather than corrupted.
But notice what Paul says immediately after warning about different teaching:
“The purpose of the commandment is love from a pure heart, from a good conscience, and from sincere faith” (First Timothy 1:5).
Paul does not place sound teaching on one side and love on the other. Proper teaching is supposed to produce something in the people receiving it.
That should give us our first warning against creating a false choice. Biblical doctrine and biblical love are not competitors.
Timothy Was Told to Watch Two Things
Paul later gives Timothy an instruction that deserves more attention than it sometimes receives:
“Take heed to yourself and to the doctrine. Continue in them” (First Timothy 4:16).
Timothy was responsible for teaching sound doctrine. Yet Paul did not merely tell him to watch everybody else’s theology.
Watch yourself.
And watch the teaching.
That order is worth pondering.
It is possible to become so occupied with identifying error in someone else that I stop examining myself. I may become very skilled at recognizing another person’s assumptions while remaining almost blind to my own.
Paul does not permit Timothy that luxury.
Second Timothy gives us another important piece. Scripture is “profitable for doctrine, for reproof, for correction, for instruction in righteousness” so that the person of God may be “complete, thoroughly equipped for every good work” (Second Timothy 3:16–17).
Doctrine therefore has a destination. Scripture teaches, reproves, corrects, and trains. The objective is not merely that I possess correct theological information. Something is supposed to happen to me.
Sound doctrine should produce a life increasingly shaped by the One whose teaching I claim to believe.
Then Why Do We Disagree?
If Christians have the same Scriptures, why do sincere believers sometimes understand them differently?
There is probably no single answer.
We do not approach Scripture as blank sheets of paper. We have languages, cultures, histories, experiences, teachers, churches, families, assumptions, and traditions. Most of us encountered some understanding of Christianity before we ever investigated Scripture independently.
Translation adds another layer. The biblical writings came to us primarily in Hebrew, Aramaic, and Greek. English translations necessarily involve decisions about how to represent words, grammar, idioms, and constructions. Usually those decisions communicate the text remarkably well. Sometimes an English word carries associations the original expression did not, or one original word has a range of meaning that no single English equivalent can capture.
Then there is context. One reader may emphasize one passage while another begins somewhere else. One may read a statement primarily through Paul, another through John, another through the Torah or the Prophets. One may see continuity where another sees discontinuity.
And then there is theological inheritance.
Catholic, Orthodox, Lutheran, Reformed, Wesleyan, Baptist, Pentecostal, Anglican, Anabaptist, and other Christian traditions did not arise in historical vacuums. Each developed within particular circumstances, controversies, questions, and inherited ways of reading Scripture. Within those broad traditions, differences remain.
Recognizing this does not prove that every interpretation is equally correct. It also does not mean truth is unknowable.
It simply means that reading Scripture and interpreting Scripture are not always the same activity.
What Does Scripture Say, and What Do I Believe It Means?
This may be one of the most important distinctions in any doctrinal investigation.
There is what Scripture states.
There is what Scripture may imply.
And there are conclusions we infer from what Scripture states.
Inference is not automatically wrong. Much human reasoning necessarily involves inference. Sometimes an inference may be strongly supported by numerous passages.
But an inference remains something we have reasoned from the evidence.
Over time, we can express an interpretation more precisely. That formulation can become part of a theological system. The system can be taught to another generation. Eventually people may encounter the theological formulation before they encounter all the biblical passages from which it was constructed.
Then something subtle can happen.
Instead of letting Scripture produce our theology, we can begin letting our theology determine how Scripture must be read.
That does not mean every traditional doctrine is wrong. Age does not make an interpretation false any more than novelty makes one true. Christians who lived centuries before us deserve to be heard, just as contemporary scholars deserve examination.
The question is simpler:
Can I still tell the difference between what the biblical text actually says and what I have concluded that it means?
That question applies to everyone—including me.
The New Testament Already Had Disagreements
Doctrinal and interpretive disagreement did not suddenly appear after the apostles died.
The New Testament records disagreements among people who were much closer to the events than we are.
Acts 15 provides an extraordinary example. Some believers taught that Gentile converts needed circumcision according to the custom of Moses to be saved. Paul and Barnabas had “no small dissension and dispute with them” (Acts 15:2).
The matter was serious. They did not pretend the disagreement did not matter.
The apostles and elders gathered to consider it. There was discussion. Peter spoke. Paul and Barnabas reported what God had done among the Gentiles. James appealed to Scripture. They concluded and communicated it to the churches.
Disagreement required investigation.
But Scripture also records disagreements of another kind.
Romans 14 describes believers reaching different conclusions concerning food and the observance of days. One believes he may eat all things; another eats only vegetables. One esteems one day above another; another esteems every day alike.
Paul does something fascinating.
He does not require everyone to reach the same conclusion before they can accept one another.
“Let each be fully convinced in his own mind” (Romans 14:5).
Yet conviction comes with a warning. The person who eats must not despise the one who does not, and the person who abstains must not judge the one who eats.
Apparently, being convinced does not permit me to despise someone who is convinced differently.
That does not mean Romans 14 can be stretched over every theological disagreement. Paul certainly did not treat every teaching as a matter of individual conviction.
Galatians demonstrates that clearly.
Not Every Difference Is Harmless
Paul could be remarkably patient with disagreement, but he could also be uncompromising when he believed the gospel itself was being distorted.
In Galatians 1:6–9, he warns about a “different gospel.” First Timothy warns about other doctrine. First John 4:1 tells believers, “do not believe every spirit, but test the spirits, whether they are of God.” First Thessalonians 5:21 says, “Test all things; hold fast what is good.”
The New Testament therefore does not permit us to solve doctrinal disagreement by declaring that doctrine does not matter.
But it also does not permit us to classify every disagreement as heresy.
That leaves us with work to do.
We must examine the teaching.
We must examine Scripture.
And perhaps most uncomfortably, we must examine ourselves.
How Do We Correct Someone Wrong?
Suppose after careful investigation I remain convinced that another believer is wrong.
What then?
Paul gives Timothy unusually specific instructions:
“A servant of the Lord must not quarrel but be gentle to all, able to teach, patient, in humility correcting those who are in opposition” (Second Timothy 2:24–25).
Read that carefully.
Paul does not say error should never be corrected. He explicitly speaks of correcting someone in opposition.
But he also governs the behavior of the person doing the correcting.
Do not be quarrelsome.
Be gentle.
Be patient.
Correct with humility.
Immediately before this, Paul tells Timothy to “avoid foolish and ignorant disputes, knowing that they generate strife” (Second Timothy 2:23).
Apparently, not every argument needs to be won.
That presents us with a difficult possibility:
I can be correct about the doctrine and still be wrong in the way I treat the person whose doctrine I am correcting.
If my defense of biblical teaching requires me to ignore biblical teaching about gentleness, patience, humility, and love, something has gone wrong.
Different Biblical Worldviews
Another layer lies beyond individual doctrines.
People sometimes approach the entire biblical story differently.
One person sees certain passages primarily through the lens of covenant. Another sees dispensations. Another emphasizes kingdom. Another emphasizes sacrament. Another emphasizes restoration. Another begins with the church fathers. Another begins with the Reformation. Another attempts to reconstruct the first-century Jewish setting. Still another concentrates heavily upon the original languages.
These frameworks can help people notice genuine patterns.
They can also become lenses.
A lens is useful because it helps us see. But if we forget we are wearing it, we may assume everyone looking at the same text must see exactly what we see.
This is where genuine conversation becomes valuable.
Someone who disagrees with me may be wrong.
But another possibility is worth considering.
He may have noticed something I missed.
That does not require surrendering conviction. It requires humility.
Acts 17:11 describes the Bereans as receiving the word “with all readiness” while searching the Scriptures daily to determine whether what they were hearing was so.
Notice the combination.
They listened.
And they examined.
Those activities were not enemies.
Love Does Not Mean Doctrinal Indifference
When Jesus said His disciples would be known by their love for one another, He was not telling them that truth no longer mattered.
Likewise, when Paul wrote that love “rejoices in the truth” (First Corinthians 13:6), he did not separate love from truth.
Perhaps our mistake is assuming we must choose between them.
Biblical love does not require me to say that something is true when I believe Scripture demonstrates otherwise. Biblical conviction does not require me to treat another person as an enemy because we disagree.
Jesus joined love and obedience: “If you love Me, keep My commandments” (John 14:15). He also commanded His disciples to love one another as He had loved them (John 13:34).
Truth without love can become a weapon.
Love detached from truth can become sentimentality.
The New Testament gives us neither option.
Perhaps the Hardest Doctrine to Examine Is My Own
It is easy to investigate someone else’s theology.
I can identify where their tradition influenced them. I can find their assumptions. I can point out where they moved from explicit statement to inference. I can explain how their denomination developed historically.
But then Paul whispers something uncomfortable through his instruction to Timothy:
“Take heed to yourself and to the doctrine.”
Myself first.
Then the doctrine.
Before asking why another Christian cannot see what seems so obvious to me, I should ask some questions about my own understanding.
Where does Scripture actually state this?
Where am I drawing an inference?
What assumptions did I bring to the passage?
Did I learn this conclusion before I examined the text for myself?
Have I listened carefully to the strongest biblical evidence offered by someone who understands it differently?
Would I recognize evidence against my interpretation if I encountered it?
And perhaps the most difficult question:
Am I willing to be corrected?
If the answer is no, then my investigation has already reached its conclusion before I open the Bible.
One Lord, Many Students
Christians will probably continue disagreeing about Scripture until the Lord Himself settles everything we have misunderstood.
That does not make doctrine unimportant. It makes humility indispensable.
We should study carefully. We should test teaching. We should preserve sound doctrine. We should correct serious error when correction is necessary. We should refuse to make theological indifference a substitute for truth.
But we should also remember who sits in the Teacher’s chair.
Jesus said, “One is your Teacher, the Christ” (Matthew 23:10).
The rest of us are students.
Some students have studied longer than others. Some know Hebrew and Greek. Some have spent decades studying church history. Some possess advanced theological degrees. Some have quietly read their Bibles faithfully for a lifetime.
But none of us becomes the Teacher.
That realization should not weaken our convictions. It should shape the manner in which we hold them.
When another believer disagrees with me, I can listen without surrendering conviction. I can examine his evidence without accepting his conclusion. I can explain why I understand the passage differently without attacking his character. If correction is necessary, I can correct without quarreling. If I discover that I was wrong, I can change my understanding without believing that God’s Word failed.
And through all of it, I can love the person standing across from me.
Perhaps that is part of what sound doctrine is supposed to produce.
The purpose is not merely to become people who can identify error in everyone else.
It is to become people increasingly shaped by the truth we claim to believe.
So when I encounter a different doctrine or biblical worldview, perhaps my first question should not be, “How do I prove this person wrong?”
Perhaps I should begin with three quieter questions:
What does Scripture actually say? What have I inferred from what it says? And can I examine the difference while still loving the person who sees it differently?
If I cannot do the third while investigating the first two, more than one doctrine may need examination.
