Christian Theology
This guide helps you get your bearings in Christian Theology before you start exploring the interactive timeline, framework graph, and concept maps.
Before You Dive In
- Christian theology is not one unified system — it spans patristic, scholastic, Reformation, liberal, neo-orthodox, liberation, and postmodern movements, each with different methods and assumptions.
- The central debates recur: How do faith and reason relate? Is salvation by grace or works? How is Christ both divine and human? Each era re-engages these questions.
- Start with the distinction between systematic theology (building a coherent doctrinal system) and historical theology (how doctrines developed over time).
- The Reformation (Luther, Calvin) vs. Catholic scholasticism (Aquinas) split is essential for understanding why Protestant and Catholic theology still differ methodologically.
- 20th-century theology fractured dramatically: Barth's neo-orthodoxy, Tillich's correlation method, liberation theology, and postliberal narrative theology represent genuinely different projects.
Key Terms to Know
TrinityThe doctrine that God is three persons (Father, Son, Holy Spirit) in one being — defining Christian theology since the 4th century councils.
SoteriologyThe study of salvation: how, why, and for whom Christ's work achieves redemption.
ChristologyThe study of Christ's nature — especially the relationship between his divine and human natures (Chalcedonian definition, 451 CE).
Natural theologyThe project of knowing God through reason and nature, without revelation (Aquinas's Five Ways are the classic example).
EschatologyThe study of last things: death, judgment, heaven, hell, and the end of history.
Common Confusions
Confusing theology with religious studies — theology works from within a faith tradition and asks normative questions; religious studies examines religion from outside.
Assuming medieval theology was dogmatic and uncritical — scholastic disputation was a rigorous method of structured argument and counterargument.
Thinking "liberal theology" means politically liberal — it refers to a 19th-century movement (Schleiermacher, Harnack) that adapted Christianity to modern thought.

1
Explore the timeline
Open the interactive view and scan the framework timeline. Which frameworks came first? Which ones overlap? Where are the big transitions?
2
Read the articles
Click into individual frameworks to read what each one claims, where it came from, and how it relates to its neighbors.
3
Check the concept map
See how the key ideas within a framework connect. This is useful for figuring out what to learn first and what depends on what.

Test yourself
Take the quiz for any framework you've read about. It's a quick way to find out whether you actually understood the core ideas or just skimmed them.
