Last time I gave three key terms (doctrine, theology, and world view) with an analogy (a brick, a wall, and a castle) to help you think about them. Today, I want to show you three different methods to building castles.
The first method is called Historical Theology. This looks at Christian doctrines down through the ages, how they have been formulated and developed over the past two millennia. It will include studying the thought of famous theologians like Augustine, Aquinas, Luther, Calvin, and Barth, etc. One disadvantage of this approach is it presupposes you already have some background knowledge of scripture. Without this background knowledge this method can be like building a castle without blueprints – you are likely to miss large sections of load-bearing walls, and have to demolish and rebuild continually as you discover more.
The second method is called Biblical Theology. Abandoning our analogy for another, Biblical theology is like a fisherman who casts his net over the whole of scripture and gathers in all the knowledge of the Bible. It will also include the historical, cultural, and religious contexts from which the Bible was written. It looks at how specific doctrines are received and developed throughout the overarching biblical story. This method is good, but it also presupposes you have a good overview of the whole picture. It can be like tying to piece together a puzzle from the inside moving out to the edge, rather than framing the puzzle first with the edges pieces.
The third method is called Systematic Theology. You may hear people describe this as a progression of themes. Systematic theology is often organised in themes, but it is more than simply Thematic Theology, which would be a sub-category of Biblical theology. It is like the fisherman, who casts his net not only over scriptural truth, but also truth from nature, reason, science, philosophy, and even experience, and then hauls in his catch to sort everything in an ordered way. In other words, a systematic theologian, by grouping together the biblical data with data from diverse sources, creates a sensible, structured understanding. To go back to our first analogy: a thoroughly grounded, well-planned, sturdy castle.
Different people will organize their systematic theology differently, but usually the order goes something like this;
Prolagomia – Preliminary remarks (we are here at the moment)
Bibliology – The doctrine of revelation
Theology Proper – The doctrine of God
Patriology – The doctrine of the Father
Christology – The doctrine of Christ
Pheumatology – The doctrine of the Holy Spirit
Angelology – The doctrine of angels
Demonology – The doctrine of demons
Satanology – The doctrine of Satan
Anthropology – The doctrine of man
Harmatiology – The doctrine of sin
Soteriology – The doctrine of salvation
Ecclesiaology – The doctrine of the church
Eschatology – The doctrine of last things
Each of the three methods above will include aspects of the other, and each has its weakness. Systematic theology for instance is vulnerable to “proof texting” – pulling out verses to prove a doctrine without due consideration of the verse’s immediate textual context. Good Christian bookstores will display the above methods in separate sections, and you should now be able to quickly tell what method any book on theology is using by flipping through it.
