What is a doctrine?
A doctrine is a set of beliefs, a principle or creed of principles, or a system of beliefs held and taught by a church, political party, or another group.
Like every major world religion, Christianity has its doctrines, which can be classified as major (fundamental) and minor doctrines.
The Importance of Doctrines
Why are doctrines important? And why should Christians know the doctrines of the Bible?
Knowing God More Deeply
The primary reason for studying doctrine is our love for God. If we love Him, we will desire to know about His nature, character, purposes, commandments, and redemptive work.
Sound doctrine helps us grow in faith and deepen our relationship with Him.
Shaping Our Spiritual Life
What we believe influences how we live. Our understanding of God affects our relationship with Him.
If one denies Christ’s deity, they reject His role as the sole mediator between God and man. Similarly, misunderstanding the Trinity, which is the Christian doctrine that defines God as three distinct individuals in one essence—Father, Son, and Holy Spirit— distorts our comprehension of God’s eternal love and unity.
Guiding Our Daily Life
A firm grasp of biblical doctrine equips believers to navigate complex moral and ethical decisions. The Bible does not explicitly address every modern issue, but doctrine helps us apply biblical principles to all aspects of life, such as issues related to social justice, family dynamics, and personal integrity.
Defending the Faith
Christians must be able to articulate and defend their beliefs. Peter urges believers to always be prepared to give a reason for their hope (1 Peter 3:15).
Whether responding to skeptics or helping seekers understand Christianity, a strong doctrinal foundation is essential.
Evangelizing with Confidence
Sound doctrine strengthens our ability to share the gospel effectively. Understanding salvation, grace, and Christ’s atonement enables believers to communicate the gospel clearly and accurately.
Answering Difficult Questions
Doctrine provides answers to some of life’s toughest questions:
How can a loving God allow suffering?
What happens after death?
Why did Jesus have to die?
What is the purpose of life?
Without a doctrinal foundation, Christians risk giving incomplete or incorrect answers that fail to address these profound questions adequately.
Dorothy Sayers, in her essay Creed or Chaos, warned against practicing Christianity without understanding its foundational doctrines:
“It is worse than useless for Christians to talk about the importance of Christian morality unless they are prepared to take their stand upon the fundamentals of Christian theology. It is a lie to say that dogma does not matter; it matters enormously… The brutal fact is that in this nation only a tiny fraction of people knows what the Church teaches about God, man, society, or the person of Jesus Christ.
Sound Doctrine
Doctrine must be true and sound. It must come from God, not from human traditions (John 7:16).
The apostle Paul emphasized sound doctrine in multiple letters (1 Timothy 1:3, 10; Titus 1:9), warning against false teachings. John also instructs believers to reject those who do not abide in the doctrine of Christ (2 John 9-10).
Fundamental Doctrines of the Christian Faith
Christian doctrines fall into two categories:
? Major (Essential) Doctrines
These doctrines impact salvation and are necessary for true Christian faith.
? Minor (Secondary) Doctrines
These doctrines, though significant, do not determine one’s salvation. Christians may hold differing views on these matters while remaining in fellowship.
The Five Essential Doctrines of Christianity
The Trinity
There is one God in three persons: Father, Son, and Holy Spirit. Each person of the Trinity is fully God, co-equal, and co-eternal, yet there is only one God (Matthew 28:19, 2 Corinthians 13:14).
This doctrine is essential because it defines the very nature of God and undergirds the Christian faith. Denying the Trinity leads to a misunderstanding of God’s love, salvation, and the deity of Christ.
The Person of Jesus Christ
Jesus Christ is fully God and fully man. He has existed eternally as God the Son and took on human flesh through the Incarnation to redeem sinners (John 1:1, 14; Colossians 2:9). His sinless life, sacrificial death, bodily resurrection, and ascension into heaven affirm His divine and human natures.
Without this doctrine, salvation would be impossible, as only a sinless and divine Savior could atone for humanity’s sins.
Salvation by Grace Through Faith
Salvation is entirely by God’s grace, received through faith in Christ alone. It is not based on human effort, good works, or religious rituals (Ephesians 2:8-9, Romans 3:28). Jesus’ atoning death on the cross paid the full penalty for sin, and His resurrection secured eternal life for believers.
This doctrine is vital because it states that salvation is a gift from God, not something we can earn.
The Authority of Scripture
The Bible is the inspired, inerrant, and sufficient Word of God. It is the final authority for faith and practice (2 Timothy 3:16-17, 2 Peter 1:20-21). Scripture is God’s revelation to humanity, teaching us about His character, redemptive plan, and moral will.
Without the authority of Scripture, Christians would lack a solid foundation for truth and doctrine, leading to confusion and false teaching.
The Second Coming of Christ
Jesus Christ will return to judge the living and the dead and establish His eternal kingdom (Acts 1:11, Revelation 22:12-13). His return will fulfill God’s ultimate plan of redemption and bring justice to the world.
This doctrine provides hope and encouragement for believers, reminding us that Christ will triumph over evil, restore creation, and reign in righteousness forever.
Conclusion
Doctrine is not an abstract academic pursuit—it is foundational to Christian life. It defines our faith, shapes our relationship with God, and equips us to live out His truth in the world.
A deep commitment to biblical doctrine ensures that we remain anchored in the truth, able to discern falsehoods, and prepared to share the gospel with confidence.
Every Christian is called to grow in the knowledge of God (Colossians 1:10), and this process begins with a firm grasp of the essential doctrines of the faith.
