Doctrine, An Introduction

Doctrine, An Introduction

Do you wear clothes? Have you ever heard of marriage? Do you enjoy weekends?

Wearing clothes, the institution of marriage, the concept of a week and weekends, and much more are doctrines of the Christian faith. The word “doctrine” seems to be lost in many churches today, yet doctrine guides every aspect of a believer’s faith, life, origins, and practice.

What Is Doctrine?

The term "doctrine" refers to a set of beliefs or teachings based strictly on God’s Word that are held and promoted by the Church as authoritative. Many of these are core, foundational truths that guide all aspects of a believer’s life.

Doctrines are developed because we take God and His Word as the absolute starting point—what greater foundation could there be? From there, we study what God reveals in the Bible and develop doctrines based on specific studies of His Word.

When we study God, we are engaging in theology—the doctrine based on Scripture about who He is (i.e., the character and person of God) and what He is like (i.e., the nature of God). The Greek word theos means "God," and -ology means "the study of," so the doctrine of God is called theology. In modern times, the term theology has come to mean the study of any major biblical topic.

Key Doctrines of Theology

Doctrines include beliefs about all three persons of the Godhead, which can be studied separately or collectively as the Triune God (Triadology):

  • Triune God (Triadology)
  • God (Theology)
  • Christ (Christology)
  • Holy Spirit (Pneumatology)

Doctrines Rooted in Genesis

Doctrine also includes beliefs about Creation (Creationology or Creation Ex Nihilo). Few realize that every doctrine of theology—directly or indirectly—has its foundation in Genesis, particularly Genesis 1–11. Many doctrines of Christianity, as well as concepts found in other world religions, openly borrow from God’s Word because these doctrines cannot be justified within their own religious systems! Consider just a few key doctrines found in Genesis:

Doctrines About Scripture

Some of the most significant doctrines concern the Bible itself. The study of Scripture is called Bibliology, which includes:

  • Inerrancy of Scripture
  • Inspiration of Scripture
  • Authority of Scripture
  • Sufficiency of Scripture
  • Infallibility of Scripture

There are many more doctrines, including those reaffirmed during the Reformation in the 1500s (e.g., the 5 Solas), fundamental doctrines (such as love, faith, hope, and grace), and more.

The Purpose of Learning Doctrine

In future installments, the aim is to provide an overview of a wide range of doctrines from a biblical authority perspective. Some doctrines are non-negotiable because the Bible is crystal clear on them.

However, in some cases, different churches interpret doctrine differently. Creeds, Confessions, and Statements of Faith outline the doctrinal positions of various denominations. In such instances, I hope to provide historical background, an overview of different positions, and encourage readers to explore these theological discussions further—whether through their local church or personal study.

In other words, this is not to convince you of specific debated doctrines but rather to educate readers on what they are so that they can investigate them in more detail if one chooses to. Within Protestant Christianity (any church that emerged from the Reformation—not Roman Catholic, Oriental, or Eastern Orthodox), most denominations agree on major doctrines. Differences typically arise in interpretations of Revelation 20, Calvinism vs. Arminianism, modes of baptism, and a few other areas—these should be addressed in future installments.

False Doctrines and Heresies

Unfortunately, some cults, groups, “churches”, and ministries deviate from sound theology and fall into error. These deviations are called false doctrines. Some leaders impose outside ideas onto Scripture, claiming to be new prophets, promoting doctrines of men, incorporating secular views, or mixing Christianity with other religions to justify their positions.

This series will also address some of these false doctrines. Where good and true doctrines are developed from Scripture, believers must use discernment and rely on Scripture to refute false doctrines that originate outside of God's Word. In fact, some doctrines are so dangerous that God Himself warns that they are doctrines of demons.

The Final Authority

In all things, God’s Word—the 66 books of the Bible—remains the supreme authority.
