Was John Calvin a Heretic-Burning Maniac?

John Calvin is often black-eyed because of his aggressive, sometimes virulent personality. Even the Oxford Dictionary of the Christian Church claims that “Calvin was the ‘cruel’ and ‘the unopposed dictator of Geneva.’” Bruce Gordon, a Calvin biographer, states that Calvin knew how to manipulate relationships, intimidate, bully, and humiliate. In other words, he was a normal human being like you and me. Calvin seemed to be aware that his character hindered his ministry as in many of his writings he confessed and lamented his sinfulness.

For many of Calvin’s critics the infamous “Servetus affair” defines his posthumous reputation. Michael Servetus was a theologian who taught doctrines contrary to the historic Christian faith in Geneva, the city where Calvin ministered. He was arrested in August 1553 for denying the Trinity and that Christ was the eternal Son of God. He was executed two months later when he was burned at the stake. To Calvin, Servetus was outside the circle of orthodoxy, for Servetus publicly denied the essentials of the faith and encouraged people to embrace his doctrines. Calvin was zealous for God’s reputation and did play a role in Servetus’s execution. Therefore, many think that John Calvin was racing around Switzerland and all of Europe hunting down heretics. Even more, many Christians categorically dismiss the doctrines Calvin taught because of this perception.

Before assuming Calvin was a heretic-burning maniac and dismissing his teachings, consider these points:

  1. People were often executed in Calvin’s day to maintain public order, and heresy was a capital offense. Because of the inherent connection between church and state, anyone who disturbed the peace could be branded as a revolutionary who may do harm to the common good.
  2. Calvin did not oppose Servetus because he was an Arminian. In fact, Servetus was not an Arminian, but a Pelagian (he denied original sin), a Modalist (he denied the Trinity), and a Pantheist (he rejected the fundamental distinction between Creator and creation). Calvin did not oppose people who disagreed with his theological system. For example, he agreeably disagreed with the likes of John Knox over the English prayer book controversy. In reality, Calvin only opposed people who opposed the gospel.
  3. Servetus was the only person put to death for religious opinions during Calvin’s time in Geneva, even though executions for heresy were common elsewhere. Alister McGrath, a historian and Calvin biographer, states that Calvin acted more as a technical advisor or expert witness, rather than prosecutor. Additionally, the great historian Roland Bainton notes that Geneva’s prosecutor was a noted enemy of Calvin and acted independently of Calvin in Servetus’s trial.
  4. Though this may count for little in some eyes, Calvin asked that Servetus receive a more humane execution of beheading rather than being burned at the stake. Calvin’s request was denied.

In Calvin’s zeal to protect his flock, he often lacked mercy and grace, as was most certainly the case with Servetus. We must not, however, envision that if Calvin were alive today he would be seeking out heretics to roast. At the same time, we know that Calvin was not an innocent bystander in this situation; yet his legacy is not in jeopardy because of Servetus’s death.Let us remember that Calvin failed us, and not just in the Servetus affair. Like the great men and women of the faith who went before him and came after, Calvin’s virtue lies in pointing us beyond himself to the only One who never failed us and never lacked mercy and grace. Like you and me, Calvin was a great sinner in need of a great Savior.

  1. When I examined the question, I also found some other unmentioned facts. Servetus, as it turned out, originally Calvin told him to leave Geneva. He was warned that if he returned he would be put to death. He left, but he was under a death sentence by the Roman Catholic church for his heresy. So he returned to Geneva. He was allowed to remain in Geneva as long as he didn’t proclaim his heresies. He refused to keep silent. While it is no excuse for the execution, Servetus went a long way and worked hard at earning it.


  2. Thank you for your reply. I am studying the beliefs of both John Calvin and Martin Luther. I didn’t know the church i attended, which has recently changed its constitution speaks highly of Martin Luther. With the title First Baptist Church as cover I’ve discovered it really is a Protestant Church under a cloak of deception.


  3. I agree with florin.

    To say that Calvin was the least bit justified by being a child of his times denies the fact that he acted in contradiction to what he himself put in his Institutes – that heretics should not be burned at the stake or otherwise executed. The reason? He himself was pursued by the Roman Catholic Magesterium for heresy in France before fleeing to Geneva. Church and state were hardly separate under any modern USA notion, so he in the very least shared in the responsibility for Servetus’ execution, and the execution of other heretics. It can be argued that Calvin took the easy way, instead of doing the right thing and persuading the government of Geneva not to execute anyone at all, especially about spiritual matters. The fact of theocracy in Calvin’s time gave him great responsibility for what was allowed to happen. Under a mistaken and exaggerated adoption of Old Testament principles, there was far too much bloodshed over fine points of doctrine.

    I am also persuaded that what Jesus taught about trees and fruit was meant to be applied in any age irrespective of circumstance. Florin correctly points out that Calvin’s behavior is not to be discounted when it comes to his influence as a teacher of Gospel things. Jesus made it clear that where the fruit is bad, the doctrine is just as bad and is to be rejected. Therefore we need to consider all that is historically available about all the “greats” which we now allow authority in this age practically without question.

    Thank you for listening to my views.


  4. Does anyone have the sources that show that Calvin asked for beheading, that he stayed with Servetus and pled for his repentance, or that the decision was not fully his?


  5. Did Jean Calvin not write following the execution of Servetus —
    “Whoever shall now contend that it is unjust to put heretics and blasphemers to death, knowingly and willingly incur their guilt. It is not human authority that speaks, it is God who speaks and prescribes a perpetual rule for His Church.”

    Defense of Orthodox Faith against the Prodigious Errors of the Spaniard Michael Servetus, written in 1554

    In other words, if you criticize the burning of heretics, then you are just as guilty (and presumably deserving of also being put to death) as are the heretics? And Jean Calvin claimed he was stating this not on his authority but apparently on divine authority. In other words, no criticism permitted?

    And in 1555 in the Harmony of the Gospels he spoke out against Anabaptists being “soft” on heretics.

    “This passage has been most improperly abused by the Anabaptists, and by others like them, to take from the Church the power of the sword. But it is easy to refute them; for since they approve of excommunication, which cuts off, at least for a time, the bad and reprobate, why may not godly magistrates, when necessity calls for it, use the sword against wicked men?”
    (context — commentary on Matthew 13:39 [parable of the wheat and the tares, so clearly in reference to heretics and not criminals)

    According to one writer “In 5 years as magistrate of the Geneva “church-city-state,” Calvin oversaw 58 death sentences and the exile of 76 people.”

    And in 1562 Jean Calving boasted in a letter to Baudoin concerning the execution of Servetus

    ” posterity owes me a debt of gratitude for having purged the Church of so pernicious a monster.”

    And then there was the earlier case of Jacques Gruet (an unsavory character who shocked public decency by wearing pants there were considered too short and previously been convicted for dancing) who had denounced the Geneva city state theocracy and was effectively executed for being a political discontent and opponent of the regime.


    1. The law of Moses commanded that common people put certain sinners to death. Some scriptural language says, “You must be the first to stone such…”. One of the lesser-realized reasons that no human being can be saved by dependence on the Law is because there is no shortage of instances where people failed to kill others for various sins. Unfortunately, there was a poverty of realization of the differences between the two covanents on the part of Calvin, whose New Testament teaching incorporated at least the murderous spirit spawned by the penalties prescribed in the Old Testament. For this and many other reasons Chauvin is very likely to be judged according to law, and subject to hell according to the Law’s decrees. It can be said that everybody who does not put people to death for various sins becomes an instant accessory through the mechanism of omission, by which every Christian and non-Christian can be charged. After all, who can be certain that they are not guilty of sins of omission, especially the ones we never think of or apply?


  6. It has become popular to seek to champion the villains. We think it makes us appear clever and original, and more compassionate than those “less spiritually advanced”. So, Calvin recognized his evil in his writings, did he? So the man knew what he was doing and did not stop himself, but managed to write some things in the hopes of polishing his tarnished lifetime for future readers. No, not all of us bully, manipulate and use people. Those people are called in the Bible “lovers of self”, which Calvin, by his actions, definitely was. “You will know them by their fruit” Christ said-not by self-pitying words they wrote to appear repentant. The man was full to the brim with ego-he appointed himself as one of the many who gave themselves god-like powers to force others to agree with THEM, with torture and death as the result if one did not agree. The reason the church is a shambles, a pageant of ignorance and death is because of the likes of Calvin and all those who still slavishly follow, read and excuse him, instead of reading and studying the actual Word of the Almighty, asking His Holy Spirit to teach us, and living to serve Him. “Seek justice, have mercy, walk humbly with your God”: this was certainly NOT Calvin’s life, nor of others like him. And how did he manage to miss, “I desire mercy, not sacrifice”? It had to have been intentional. If he wrote anything of any value, it would be what is already in the Bible, so his redundancy is worthless.


  7. today calvin is taken right out of his time, environment, history, and sociological background as if he is living right down the street. he was raised catholic. if he thought killing heretics was right, well, so did everyone else. i hate that any Christian ever caused the suffering of another human being. however, that in this very day calvinism is used by so many as a reason to hate others, their own brothers and sisters in Christ, is a grief to my heart. i´m not sure how anyone can read the new-testament and not believe there is some kind of pre-destination at work in our lives, but they do. sadly, they are not content to stop there. they must condemn everyone who can clearly read what the apostle Paul wrote. and not to forget Jesus who said, No one comes to me unless the Father calls him… thank you for your blog about this. here it is 2019 and it seems the anti-calvinists are angrier than ever. that spirit of vitriol and hatred, of blaming people living today for what Calvin did, is not of God. we must pity all… the watchmen fall off the wall when their hearts are filled with hatred and hatred is what i hear coming from anti-calvinists. so so sad…and yet our God allows it. i´ve thought about it a long time and i guess it has to do with being jars of clay. all of us are only jars of clay, no matter how many likes we get.
