Know What You Believe: Why Doctrine Matters*

Image by Dariusz Sankowski from Pixabay

I have never been a big fan of systematic theology. Unlike some friends of mine – men whom I admire, brothers who love to read theological literature – my eyes glaze over when I try to read theology. For me, reading theology is like reading spreadsheets. It all blurs together.

Some people are actually disdainful about doctrine. “Doctrine divides,” they complain. “Why can’t we all just love Jesus?”

Doctrine matters, for instance, precisely because it matters what we mean when we use the name of Jesus. Doctrine drills down on essential questions like who Jesus is and why we should love and worship Him.

THE TEACHER AS A LEARNER

I’m teaching a class on our church’s Statement of Faith; I’m trying to explain what we believe as a fellowship and why we believe it. And I don’t want the class to devolve into something along the lines of driver’s ed classes, a crushingly boring class you must simply endure (with apologies to any readers who teach drivers ed, of course).

So I have had to think carefully about why doctrine matters. 

In my first class, I explain what doctrines are: interlocking assumptions about key truths that control the way we think, key truths like

-- who God is: His attributes, the Trinity

-- human nature: what makes humans such splendid creatures, capable of such great things, but also so corrupt and capable of great wickedness

-- how we can deal with the brokenness in our nature, how I cope with the fact that I can’t even live up to my own standards, much less withstand the scrutiny of a holy God

-- who Jesus was and is: what He accomplished at the cross, what happened on that magnificent Sunday following His death, our expectation that we will see Him again

-- what role the Bible ought to play in our lives and in our thinking

In other words, doctrine is about the bedrock issues of our how we perceive and interpret what we see and experience. 

Doctrine matters because of how important these key truths are.

This is why we need to have a firm grasp on what we believe. Fuzzy thinking about money or time management has consequences. Procrastination will almost always create problems. Always having “too much month at the end of my money” can bring about real difficulties. But fuzzy thinking about doctrine is a matter of spiritual life and death. 

This is why Paul says that helping God’s people grow theologically is one of the primary responsibilities of Christian leaders. He uses a terrifying word picture – babies floundering in the water – to describe what happens when we get stuck in spiritual immaturity because we don’t have a good grasp on doctrine: 

And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes. Eph 4:11-14, ESV

We cannot afford to be careless in our thinking about God, about our own nature, about our sin, about Jesus, about the Bible. If our doctrine is shaped by the culture or our own life circumstances or (worse yet) social media, we will find ourselves vulnerable to deception and error. 

HOW DOCTRINE OPERATES BENEATH THE SURFACE

Doctrines are articulated in statements, but doctrine usually operates as a set of unconscious assumptions. Doctrines function like an operating system in a computer, always running in the background, controlling the way we think and react. The way we think about these key ideas isn’t usually intentional; we don’t consciously rehearse our views on these matters every day. But we operate on those assumptions all the time. 

-- We assume that God is interested in our well-being, a wise and generous Father; or we assume that He is remote and disinterested. 

-- We assume that people are basically good and well-intentioned; or we assume that people are inwardly corrupt and self-serving. 

-- We assume that the life of Jesus was the fulcrum on which human history turned and that He’s coming again to make all things right; or we assume that He was only a kind and good teacher, one of the great moralists of history, who showed us how to live more ethically.

This is why we read Scripture and we sometimes refer to the creeds in our sermons, because we are forgetful. In a culture that always ignores sound doctrine and sometimes attacks it, it is far too easy to give head space to faulty assumptions about God, ourselves, Jesus, the Bible. So we need to remind ourselves frequently of these key truths, these bedrock doctrines.

WHY THE ASTERISK*

Why the asterisk in the title? The asterisk is there because of the sad fact that it is possible to be an expert in sound doctrine that doesn’t actually matter.

For doctrine to matter in my life, it must penetrate my heart, it must have an impact on my character and my priorities, particularly on the way I treat people. If I have all the key doctrines locked down but I am arrogant and impatient, my doctrine is no more significant than, as Paul describes it, “a noisy gong or a clanging cymbal” (1 Cor 13:1). 

Social media is full of arrogant, impatient doctrine warriors pounding their gongs and clanging their cymbals, filling the web with vitriol

and taking pleasure in their devastating critiques on the doctrines of other believers. If my doctrine doesn’t make me humble and compassionate, either my doctrine isn’t actually Christian or I don’t really understand Christian doctrine.

So, yes, doctrine does matter because I need to have a good grasp on what I believe. And because I am forgetful, I need to often remind myself and be reminded of key truths about God, my own heart, Jesus, the Bible. 

Someday, in the next life, when we have reached our glorified state, we will see all things clearly, and all the key truths that we have in doctrine will be obvious and self-evident. But for now, we need to remind ourselves, to remember the doctrines, so we don’t forget.

Four Reasons Why the Echo Chamber Is So Dangerous

Image by  Naji Habib  from  Pixabay When the pandemic first began to change our way of life, I wrote that crisis would reveal things to us about ourselves, things we might not want to know. I’m not happy about how right I was. What we have learned in those darks times about the Christian witness in the marketplace of ideas is discouraging, if not disturbing. If our social media posts are any indication, •          we Christians are more anxious than we ought to be •          we are easily duped •          we are angry and irritable •          and we aren’t paying much attention to God’s Word Why are these things so? Why are so many people who have been bought by the blood of Christ thinking and speaking and acting so much like people who don’t know him? There are probably many answers to that question...

How Biblical Stewardship is Less Like Accounting and More Like Starting Your Own Business

Image by senivpetro on Freepik When you hear a pastor mention “stewardship,” it usually means he’s going to talk about money. So the whole topic of stewardship often ranges somewhere between tedious and awkward. Stewardship does have to do with money, of course, but the biblical understanding of stewardship is far richer and deeper than mere money management. Many Christians have a one-dimensional view of stewardship. Their approach to stewardship runs something along these lines: “carefully managing my money so that I can give God His 10% share so that I still have enough to meet all my present and future wants and needs.” That understanding of stewardship is faulty on several counts. The most obvious is that a steward is not an owner, but the popular understanding of stewardship focuses almost all its attention on the self (go back and notice the four first-person singular pronouns in that definition). But there’s a deeper problem that me-centered way of thinking about steward...

The Day I Learned "Grace"

Image by  Pexels  from  Pixabay I know people go to seminary to learn theological terms, and I learned plenty of -isms and -ologies during my summers at Dallas Theological Seminary. But one term - grace - found its mark deep in my heart because of something Michael Green did. Michael Green was a young professor who taught the required course on evangelism. He was big on personal responsibility and organization. “You’re in seminary now,” he would say. “There’s no excuse for late or sloppy work,” and many other exhortations to that effect. One of the class requirements was a take-home test, which we were to grade in class on a certain day. As I did every summer at DTS, I had dutifully noted all my due dates for all my projects in all my courses on a calendar after the first day of class, but I had written down the wrong date for this take-home test. I didn’t realize my error at first.  This day I came to my class on evangelism, and I heard my classmates discussing the ...
