John Knox in the Resistance Tradition
John Knox sits inside a broader Protestant lineage of writers and pastors who argued, against the absolutist claims of kings, that civil rulers are bound by law and that subjects retain a right — and at times a duty — to resist tyranny. The sources T.Rex stocks on this question do not isolate Knox as a single-volume study; they place him within a continuous tradition that runs from the Reformation through the English Civil War and on into the American Founding. To understand Knox’s contribution to the English constitutional tradition, it helps to see the chain of arguments that other Reformed writers were building at the same time and immediately after.
The Reformation’s Political Question
The Reformation began as a theological correction inside the Roman Catholic Church. When Rome refused to hear it, the movement pushed outward and emphasized personal responsibility, religious liberty, and decentralization of church authority. That emphasis carried an unavoidable political implication: if church leaders could be questioned and limited, civil leaders could be questioned and limited as well.
Several European monarchs disliked this implication as much as the Pope did, and they responded with persecution. The French Huguenots were among the most brutally treated. Out of that crucible came one of the foundational resistance texts, Vindiciae Contra Tyrannos: A Defense of Liberty Against Tyrants, published in 1579 under the pseudonym Stephen Junius Brutus. The book worked through four questions:
- Whether subjects must obey princes who command against the law of God
- Whether it is lawful to resist a prince who breaks God’s law or ruins His Church, and by whom
- Whether it is lawful to resist a prince who oppresses or ruins a public state
- Whether neighboring princes are bound to aid the subjects of other princes who are persecuted for true religion or oppressed by manifest tyranny
The Huguenots did not stop at theory. They organized resistance through free men and lesser magistrates and won significant freedoms to govern their own provinces. Knox’s Scottish work paralleled this French Reformed thinking and fed into the same intellectual current.
From Knox to Rutherford
The constitutional crisis Knox anticipated came to a head in the next century in Britain. In 1598 King James I wrote The True Lawe of Free Monarchies, declaring that a monarch holds absolute authority over his subjects and is an unlimited sovereign. His son Charles I took that doctrine seriously, overruled Parliament, violated the rights of citizens, and broke long-established English laws.
In 1644 the Westminster pastor Samuel Rutherford answered with Lex Rex: The Law and the King. Rutherford argued, across forty-four questions, that law is sovereign and that earthly monarchs are limited by it. The book directly motivated and guided the parliamentary forces and the English people who resisted Charles during the English Civil War. When the Royalist armies were defeated, Charles I was tried and executed on the very principles Rutherford had set out.
Rutherford’s questions track closely with the territory Knox had opened a generation earlier:
- Whether sovereignty is so in and from the people that they may resume their power in time of extreme necessity (Q9)
- Whether the people make a king conditionally or absolutely, and whether the king is tied by such a covenant (Q14)
- Whether the king is above the law (Q26)
- Whether wars raised by the estates and subjects in their own just defense against the king’s bloody emissaries are lawful (Q28)
- Whether self-defense, by opposing violence to unjust violence, is lawful by the law of God and nature (Q31)
After Rutherford’s death, Charles II ordered Lex Rex burned. The book survived. American Founders later relied on it when they confronted a similarly misguided monarch.
The Theological Backbone
The resistance tradition Knox helped shape is not a secular or purely contractual argument. It rests on a specific reading of Scripture about the duties of magistrates and the rights of God’s people. Phillip Kayser’s short volume The Divine Right of Resistance works that biblical case directly: what God’s Word says about submitting to governments, disobeying tyrants, the responsibilities of the civil magistrate, and the rights of individuals. It is a compact introduction to the same texts and principles Knox, the Vindiciae author, and Rutherford each brought to bear.
The core theological moves are consistent across the tradition:
- Civil government is warranted by divine law and the law of nature, but is not itself ultimate
- Royal power is mediated through the people, not delivered immediately and without limit from God to the king
- The king is a fiduciary or ministerial office — closer to a tutor, husband, or steward than a lord or dominator
- The safety of the people is a higher law than the will of the king
- Passive obedience is not the only Christian option; defensive resistance has biblical warrant in the examples of David, the people’s rescue of Jonathan, Elisha, and the eighty priests who resisted Uzziah
Resistance Through the Lesser Magistrate
A distinctive feature of the Knoxian and Reformed strand of this tradition is its emphasis on the lesser magistrate. Resistance is not framed as private vigilantism or mob action. The Vindiciae argued that organized resistance was carried out by free men and lesser magistrates together. Rutherford devoted whole questions to the role of inferior judges, the estates of parliament, and the power they hold relative to the king. The argument is that subordinate civil officers have an independent duty to uphold the law against a higher officer who breaks it, and that they may lawfully shield the people from a tyrant who would otherwise act with impunity.
This is the structural logic that made the English Civil War, and later the American Revolution, defensible in the categories the Reformers had built. It is not innovation by rebellion; it is law-keeping by officers who refuse to participate in lawlessness from above.
Continuity Into the English and American Tradition
Glenn Sunshine’s Slaying Leviathan traces this lineage as a continuous Christian tradition: the early Church, Augustine, the medieval recognition of natural rights, law and government in the Protestant Reformation, Protestant resistance theory, resistance theory in Britain, Locke in his proper context, and the American Founders. The thread running through all of it is a definite claim about inalienable individual rights and definite limits on civil government. Justice requires civil government to uphold the law and also requires that government to be restrained by individuals when it departs from the law.
Knox belongs near the headwaters of that British branch. His insistence that idolatrous and tyrannical rulers could be lawfully resisted was not an isolated Scottish eccentricity. It was a working-out of Reformation premises that Huguenot writers, Rutherford, and eventually the American colonists would all draw on. The same arguments that justified resistance to Charles I were available, in unbroken form, to men confronting George III a century and a half later.
For readers tracing the English constitutional tradition, the practical reading order is straightforward: Kayser for the biblical foundations, the Vindiciae for the first major systematic Reformed treatment, Lex Rex for the mature argument that brought down a king, and Slaying Leviathan for the historical map that places Knox and the others in their proper sequence.
