What is systematic theology? it is any study that answers the question, “What does the WHOLE Bible teach us today about any given topic?” It involves collecting and understanding all the relevant passages in the Bible on various topics and then summarising their teachings clearly so that we know what to believe about each topic.

In a secondary way, we also then refer to the teachings of the generations gone by to make sure we have not interpreted in vain. Studying church history, particularly the ministry gifts of God and key theologians writings, significantly deepens our comprehension of the Bible’s teachings across various subjects. It will be foolish to think that God has not given revelation to other people throughout church history and not compare your own to it.

Someone might ask: “Why not just accept what the Bible says as it is, without trying to organise it into systems or explain how everything fits together?” The answer is: you actually can’t do that for long.

Human beings naturally try to organize and connect information. When we learn facts, our minds automatically look for patterns, meaning, and how everything fits together. We don’t like having scattered or unrelated ideas. This happens in every area of life—not just the Bible. People always try to systematize knowledge (science, history, etc.), rather than leaving it as random facts.

So, when it comes to the Bible, Christians also naturally try to:

• connect teachings together
• resolve apparent contradictions
• understand how doctrines relate

Because of this, theology systems are unavoidable. Throughout church history, every group has ended up forming some kind of structured way of explaining Bible truth.

In short:
We don’t just collect Bible facts—our minds naturally try to organize them into a system, so theology systems will always exist.

We can do a whole seminar on faith, and yet if we do not teach on how it works by love, we will have a whole group of hurt people in the church. We can shout from the pulpits “have faith” but if we do not teach people on how to get faith, faith cannot come. If we touch on love without touching on the shedding abroad of Gods love in our hearts by the Holy Spirit, we will walk in natural human love. So all teachings are connected.

The Bible contains past, present and future truths. Jesus was prophesied about in the Old Testament and lived among us in the New Testament gospels. Today, He sits at God’s right hand. Therefore, the present truth is He is seated on the right hand side of God. The future truth is His return to reclaim us. Systematic theology aims to summarise each doctrine for us, enabling them us to “BE ESTABLISHED IN THE PRESENT DAY TRUTH”.

We sometimes use terms and concepts not found in any single Biblical author’s writings but that arise from combining teachings from two or more authors on a specific subject. The terms Trinity, incarnation, and deity of Christ, for example, are not found in the Bible, but they usefully summarise biblical concepts. Many today ask where is the trinity mentioned in the Bible? The fallacy is the same as asking where chapter and verse are mentioned in the Bible! The system of chapter and verse was invented by man and makes it easy for man to find scriptures easily.

Systematic theology will immerse you in Scripture, fostering spiritual maturity and growth in grace (2 Peter 3:18). It transforms intellectual understanding empowering you to live Holy. Remember, growing in grace is linked to knowledge, so don’t treat Biblical knowledge lightly.

Different Theologies

Historical theology (a historical study of how Christians in different periods have understood various theological topics) causes doubt 

Philosophical theology (studying theological topics largely without use of the Bible, but using the tools and methods of philosophical reasoning and what can be known about God from observing the universe) causes rise of false religion

Apologetics (providing a defence of the truthfulness of the Christian faith for the purpose of convincing unbelievers). Faith is not intellectual 

Systematic theology (a thorough study of God’s word to see what it says, free from opinions) - this is the best form of study. Brings Faith.

Some people say the results of systematic theology are "too neat" and that theologians are forcing the Bible's teachings into an artificial box, twisting the real meaning to make everything fit neatly together.

Of course, poor teaching can be found among any scholars, not just theological ones. And bad teachers have caused many of problems.

It's important to be clear here because this objection often comes from people who—maybe without realising it—have picked up a doubt from our culture: the idea that we can't find real truths about anything, even about God.

A common appalling approach in evangelical churches today—we might call it "random theology" or "theology with no order"—is a weak alternative to systematic theology. It's too personal and too influenced by culture. It leads to broken and confused beliefs, leaving the church unprepared, like "children tossed back and forth by waves and blown around by every new teaching" (Eph. 4:14).

Systematic theology will ground you.

The 10 Sections Of Systematic Theology

1. Prolegomena (The Introduction)

Before diving into specific doctrines, we must establish the "rules of engagement." This section deals with methodology, epistemology and doxology. It asks: How do we know what we know? What is the authority of the Bible? How do we interpret it? All this leads to true worship.

2. Theology Proper (The Doctrine of God)

This focuses strictly on God the Father. It covers His existence, His attributes (holiness, love, omniscience), and the mystery of the Trinity. It also explores His decrees—His sovereign plans for creation and providence.

3. Bibliology (The Doctrine of Scripture)

This section examines the nature of the Bible itself.

• Inspiration: How God breathed out the text.

• Inerrancy: The truthfulness of the original manuscripts.

• Canonization: Why these specific 66 books are considered authoritative.

4. Anthropology (The Doctrine of Humanity)

This explores what it means to be human. It covers the Imago Dei (Image of God), the relationship between the body and soul, and the origin of the human race.

5. Hamartiology (The Doctrine of Sin)

Often paired with Anthropology, this section analyzes the "Fall." It looks at the nature of sin, its origin in the Garden of Eden, and Original Sin—how the rebellion of Adam affects every human born today.

6. Christology (The Doctrine of Christ)

This is the study of Jesus Christ. It focuses on the Hypostatic Union (Jesus being fully God and fully man) and His roles as Prophet, Priest, and King.

7. Pneumatology (The Doctrine of the Holy Spirit)

This section focuses on the person and work of the Holy Spirit. It covers His role in creation, His inspiration of the authors of Scripture, and His ongoing work in the life of the believer (sanctification and spiritual gifts).

8. Soteriology (The Doctrine of Salvation)

This is often the "heart" of systematic theology. It outlines the Ordo Salutis (Order of Salvation), which includes:

• Election and Calling

• Regeneration (The New Birth)

• Justification (Being declared righteous)

• Sanctification (Growing in holiness)

• Glorification (The final state in heaven)

9. Ecclesiology (The Doctrine of the Church)

This looks at the "Called Out Ones." It discusses the nature of the universal church versus the local church, the requirements for leadership (elders and deacons), and the Ordinances (Baptism and the Lord's Supper).

10. Eschatology (The Doctrine of Last Things)

Finally, we look at the end of the story. This covers death, the intermediate state, the second coming of Christ, the resurrection of the dead, the final judgment, and the New Heavens and New Earth.

Examples Of Jesus Using Sytematic Theology

Organising the Law into a Theological System

Jesus performed a brilliant feat of systematic categorization. Instead of picking one of the ten, he synthesized the entire Law and the Prophets into two vertical and horizontal pillars.

• Love God (Deut. 6:5)
• Love your neighbor (Lev. 19:18)

This is systematic theology: He reduces many commands into a unified framework

Harmonising Doctrines (Resurrection Debate)

In Matthew 22:23-33, the Sadducees—who rejected the afterlife—tried to trap Jesus with a logical puzzle about marriage and the resurrection. Jesus responded using Bibliology (how we interpret Scripture) and Theology Proper (the nature of God).

• The Logic: He quoted Exodus 3:6, where God says, "I am the God of Abraham, Isaac, and Jacob."

• The Systematic Deduction: Jesus argued that God is the God of the living, not the dead. Therefore, if God is currently their God, Abraham, Isaac, and Jacob must exist in a state of life. He used the present tense of a verb to build a systematic proof for the existence of the soul after death.

The Road to Emmaus

This is perhaps the most "academic" example of Jesus teaching systematic theology. In Luke 24:27, after his resurrection, Jesus walked with two disciples and gave what was essentially a masterclass in Christology.

The Method: He didn't just stay in one book. He moved through the entire Bible or what we call in systematic theology "canon" (Moses, Prophets Writings) to show how a single theme—the suffering and glorified Messiah—unified the diverse texts of the Old Testament. This is the definition of Biblical Theology feeding into Systematic Theology.

Without systematic theology, Bible teaching can easily drift into imbalance, exaggeration, or even error. A major cause of excess is building doctrine on a few favourite verses. Some teachings become excessive because they isolate one truth and ignore its counterpart. Faith without love, Grace without holiness. False or exaggerated teachings often sound convincing in isolation. In some circles, experience can begin to dominate truth. There was a time when unless you vomited, the demon did not come out! Unless you shouted and sweated you are not anointed, etc.

Here is a powerful example of how the devil quotes scripture and Jesus counters it with another scripture rightly dividing the word of truth:

Jesus knew the whole counsel of God and knew what scripture worked under what circumstances.
