Introduction
This free study guide accompanies the Culture Makers episode “Move the World Part 3: Law and Justice.”
We explore how the Church shaped the world’s understanding of law, justice, and moral order. From emperors and bishops to reformers and abolitionists, believers stood courageously to declare that no ruler stands above God’s law. Use this guide for personal reflection, small group discussion, or classroom study as you rediscover how God’s truth has always been the foundation of true justice and freedom.
Overview
Before Christ, law often served the powerful and oppressed the weak. But the gospel introduced a revolutionary truth — every human being bears the Imago Dei, the image of God.
Genesis 1:27
“God created man in His own image; in the image of God He created him; male and female He created them.”
This truth became the foundation for human dignity and equality.
The Church proclaimed that justice flows from the character of God Himself, who calls rulers to govern with righteousness and mercy.
Romans 13:1
“There is no authority except from God, and those that exist have been instituted by God.”
From Ambrose confronting Emperor Theodosius, to Justinian’s Corpus Juris Civilis, to the Magna Carta and the abolition of slavery, the Church’s witness shaped the moral conscience of nations.

The Church and the Birth of Moral Authority
- Ambrose of Milan confronted Emperor Theodosius after the Thessalonica massacre, declaring that even emperors must repent before God.
- Gregory of Nyssa condemned slavery as rebellion against God’s law, teaching that every person is free by nature.
- Augustine of Hippo warned that kingdoms without justice are “great robberies.”
- Thomas Aquinas taught that unjust laws are acts of violence, not true laws, because they contradict God’s eternal law.
Each of these voices reminded the world that justice is not man-made — it is revealed by God.
Law, Order, and the Christian Legacy
Emperor Justinian I (6th century)
- Built the Hagia Sophia (“Holy Wisdom”) in Constantinople
- Compiled the Corpus Juris Civilis, defining justice as “the constant and perpetual will to give each his due”
Archbishop Stephen Langton
- Helped draft the Magna Carta (1215), affirming that rulers are subject to God’s higher law
These foundations shaped Western legal tradition and the idea of constitutional government.
Proverbs 8:15
“By Me kings reign, and rulers enact just laws.”
The Gospel and the End of Slavery
The New Testament did not endorse slavery — it transformed it from within.
Colossians 4:1
“Masters, treat your slaves justly and fairly, knowing that you also have a Master in heaven.”
Philemon 1:16
“No longer as a slave, but better than a slave — as a beloved brother.”
By the 18th and 19th centuries, believers such as William Wilberforce, John Newton, and the Clapham Sect led the fight to abolish the slave trade.
They saw slavery not merely as a social evil but as a sin against God.
Their faith-driven perseverance proved that true justice flows from transformed hearts.

Closing Reflection
Micah 6:8
“He has told you, O man, what is good; and what does the LORD require of you but to do justice, to love mercy, and to walk humbly with your God?”
Justice is not an invention of man but a reflection of God’s holy nature.
When the Church lives out this truth, it becomes a light to nations — reminding the world that righteousness exalts a people, and mercy triumphs over judgment.
Ask God to give you courage to stand for truth and compassion in your generation, that His justice may move the world once again.
