The Importance Of Biblical Doctrine

The Importance Of Biblical Doctrine

The lack of solid biblical doctrine in a church can cause immense problems. When people in the church are not trained to know the truth from the Bible—then it is easy to fall into error.

If You Don’t Learn Doctrine

A church could be led astray by unbiblical teachings of a leader, false prophet, bad interpretations, syncretism (mixing Christianity with another religion), etc. Consider for a moment if a church leader begins teaching something contrary to Bible, all the while saying it was biblical? Sometimes, it even sounds good and right until it is examined and tested against God’s Word carefully. Sadly, this happens all the time.

For instance, have you ever heard a Christian leader say that “Christianity is a relationship, not a religion!”? It sounds good and it’s been repeated for decades—so much so that its origins are shrouded in mystery.

But a quick test against the Bible and you’ll find that God openly calls Christianity a religion in the book of James—twice (James 1:26 and 1:27).

If anyone among you thinks he is religious, and does not bridle his tongue but deceives his own heart, this one’s religion is useless. Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world. (James 1:26-27, NKJV)

The Christian religion is to be pure and undefiled, with bridled (i.e., restrained, kind, and pure) speech and a life unstained by the world’s false teachings. In other words, Christianity should not be mixed with false religions and the erroneous teachings of the world. Otherwise, believers might be led astray into false doctrine, which can result in improper care for widows and orphans, among other consequences.

Is Christianity a relationship with Christ? Yes, but it is also a religion—the only true religion.[1]

Consider the situation of a new believer who has just received Christ as Lord. They know very little about many doctrines! New believers need to be taught and trained in biblical teaching. That is the essence of Christian education.

Now, what happens in a church if people are not trained in doctrine? First, their spiritual growth can stagnate. Second, they could fall into error. And lastly, they will be less effective in teaching and sharing the Gospel with the next generation—because they are simply not equipped to do so.

The importance of sound biblical doctrine cannot be overstated. One should not expect children or new believers to be experts in Christian doctrine, nor able to defend biblical authority, until they are properly trained. Again, that is the purpose of Christian education!

Training the next generation of believers in doctrine and a reasoned defense of the faith (called “apologetics”) is crucial. This is why apologetics often goes hand-in-hand with doctrinal teachings.

The Levels Of Doctrine: Primary, Secondary, and Tertiary

Primary doctrines are the most important teachings of Christianity because they define the Christian faith itself. These include beliefs such as the Trinity, the deity of Jesus Christ, His death and resurrection, salvation by grace through faith, and the authority of the 66 books of the Bible. If someone rejects these core teachings, they are rejecting essential parts of biblical Christianity. Christians should be united on these foundational truths.

Secondary doctrines are important teachings that affect how churches operate and practice their faith, but Christians can still recognize one another as fellow believers even when they disagree. Examples include the proper subjects and mode of baptism, church leadership, the timing of the administration of the Lord's Supper, eschatology, post-Flood boundary, certain theological debate within the realm of biblical authority (e.g., the Calvinism vs. Arminian debate), and when to rest.

These doctrines often explain why there are different Christian denominations, yet believers who disagree on them can still share the same gospel. But they often staunchly divide on these secondary doctrines.

Tertiary doctrines are teachings that Christians may discuss and debate without causing major divisions in fellowship. Examples include what clothing to wear, what style of music in which to listen and one’s understanding of the role of demons and fallen angels. These topics are worth studying because they help believers understand Scripture more fully, but Christians should show grace and charity toward one another when disagreements arise.

A good rule is: stand firmly on primary doctrines, take solid but gracious views of secondary doctrines, and discuss tertiary doctrines with humility and respect.

A Practical Example

Sadly, many people today reject the plain teaching of Genesis 1–11 regarding origins and reinterpret it to accommodate the Big Bang, millions of years, and evolutionary ideas. Some may argue that this is merely a side issue—a secondary or tertiary doctrine at best. However, this is fundamentally an issue of biblical authority.

There is a clear denial of what the Bible teaches in Genesis 1–11: that God created the world in six days and rested on the seventh. To reject this teaching and instead accept ideas that originate from other worldviews (the Big Bang, millions of years, and evolution are subsets of secular belief systems such as naturalism, evolutionism, secular humanism, and atheism) is a direct denial of the authority of Scripture, which is a primary doctrine.

When a professing Christian does this, he or she abandons what the Lord Jesus Christ has said in His Word, beginning with Genesis. Jesus is God; therefore, the Bible—including Genesis—is the Word of Christ. This, too, is a matter of primary doctrine. Genesis 1–11 serves as the foundation for every major biblical doctrine, either directly or indirectly, and it provides the essential foundation for the Gospel itself.

Genesis should not be casually neglected in favor of ideas that come from false religions or unbiblical worldviews. As a teaching point, notice how many Christians attempt to demote the straightforward and foundational teaching of Genesis 1–11 to the level of a secondary or tertiary doctrine. The reality is that denying Genesis 1–11 is a direct attack on the authority of God's Word.

The Bible, including Genesis, comes with the authority of Jesus Christ Himself. A professing Christian should stand upon that authority, not mock or undermine it.
