This deep dive explores how Karl Barth identified Natural Theology not merely as an academic error, but as the fatal crack in the foundation that allowed the German Church to collapse into Nazism.
For Barth, the political disaster of 1933 was arguably a theological problem long before it was a political one. If you allow “nature” (history, culture, race, blood) to speak alongside Scripture, you will eventually make Scripture say what your culture wants it to say.
1. The Diagnosis: How “Natural Theology” Became a Trojan Horse
Barth’s critique centers on the movement known as the “German Christians” (Deutsche Christen). This group within the Protestant church did not reject the Bible outright; instead, they used a specific form of natural theology called the “Orders of Creation” (Schöpfungsordnungen) to twist it.
The “Orders of Creation” Heresy
This doctrine argued that God reveals His will not just in the Bible, but also through the “natural orders” He established: Family, Volk (People/Nation), and State.
The Logic: Since God created the German people and the German state, honoring these “orders” is an act of obedience to God.
The Deviation: The “German Christians” claimed that Adolf Hitler and the rise of National Socialism were a new “revelation” of God in history. They argued that the Holy Spirit was speaking through the “awakening” of the German nation.
The Result: The Cross of Christ was pushed to the side. Instead of a suffering Jewish Messiah who died for the sins of the world, they preached a “manly,” Aryan Jesus who affirmed German supremacy. Natural theology allowed them to baptize Nazi ideology and call it “Christianity.”
2. The Counter-Attack: The Barmen Declaration (1934)
Barth’s solution was not a political protest, but a theological firewall. He drafted the Barmen Declaration, and Thesis 1 is the direct rejection of this natural theology.
Barmen Thesis 1: “Jesus Christ, as he is attested to us in Holy Scripture, is the one Word of God which we have to hear and which we have to trust and obey in life and in death.”
The Rejection: “We reject the false doctrine, as though the church could and would have to acknowledge as a source of its proclamation, apart from and besides this one Word of God, still other events and powers, figures and truths, as God’s revelation.”
Why this matters:
“Other Events”: This referred to the rise of the Nazi party.
“Other Figures”: This referred to Hitler.
“Other Truths”: This referred to the ideology of “Blood and Soil.”
By asserting that Jesus Christ is the only Word of God, Barth stripped the Nazi state of any divine authority. If God speaks only in Christ, then He is not speaking through the Führer.
3. The Root Error: Religion as a Human Creation
In Church Dogmatics I/2, Barth defines “Religion” (as opposed to Revelation) as the attempt by human beings to create a god in their own image.
The Nazi Idol: The German Church didn’t want the God of the Bible (who judges human pride); they wanted a god who validated their cultural pride. They used “religion” to project their own desires (power, purity, strength) into the sky and call it “God.”
The “Antichrist”: This is why Barth used such strong language. When the church uses natural theology to blend Christ with culture, it creates an “Antichrist”—something that looks like Christianity (it has churches, pastors, sermons) but is actually worshipping the Self/Nation.
4. The Solution: Revelation in Jesus Christ
Barth’s correction—and the only hope for real salvation—is to recognize that we cannot know God by looking at our history or our success. We can only know God where He has chosen to be found: In the person of Jesus Christ.
A. The Cross vs. The Glory of the State
Natural theology looks for God in “glory” (power, success, military victory). The Gospel reveals God in “shame” (the Cross).
The Correction: If you want to know who God is, you don’t look at a marching army (even if they claim to be doing God’s will). You look at the man dying on the cross.
The Encounter: The Cross destroys the idea of the “Superman” or the “Master Race.” It reveals that all humanity—Jew and Gentile, German and French—is utterly sinful and dead, needing a Savior. It levels the playing field, making the Nazi claim to superiority theologically impossible.
B. The Threefold Form of the Word
To prevent the church from drifting again, Barth emphasized that our encounter with Christ is mediated strictly through:
The Revealed Word: Jesus Christ himself (the only source).
The Written Word: Scripture (the unique witness to Christ).
The Proclaimed Word: The sermon (faithful only when it points to Scripture and Christ).
There is no fourth category for “Nature,” “Reason,” or “Politics.”
