John Calvin’s Conversion

“Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that that are his.  And, Let every one that nameth the name of Christ depart from iniquity” (2 Tim 2:19).

The late Dave Hunt, a popular Christian author, wrote a book in which he did not exactly cover himself with glory.  In fact, it is a disappointing volume and undermines his trustworthiness, to my mind, at least.  If he could perpetuate and promote errors such as those found in his attack on John Calvin in his book “What Love is This? Calvinism’s Misrepresentation of God”, how do I know he hasn’t taken the same approach with his other books, some of which I’ve read and benefited from?

Unfortunately, this book has become very influential and many people who want to know about Calvinism turn to it.  It was even recommended to me by a Baptist pastor with whom I’ve been discussing Calvinism.  Fortunately I was able to say I’ve read it twice and found it not only tediously repetitive but offensive because of its misrepresentation of Calvin and Augustine.  It’s a book which appears on the surface to be thorough and complete, and many Christians see it as an authority. 

Of the various “mistruths” in Hunt’s books, one of the most outrageous is his claim that Calvin was not saved.  One of those who have read Hunt’s book in order to understand Calvinism is another well-known author, a Baptist named David Cloud.  He wrote a booklet against Calvinism titled “The Calvinism Debate” and one of his sources is Dave Hunt’s book; he, too, says, “Calvin never gave a testimony of the new birth; rather he identified with his Catholic infant baptism”.  It is this error which I want to refute in this article, and show that Calvin was biblical through and through, having been washed in the blood of the Lamb and born anew by the Holy Spirit and the Word of God.  The change in his life was total and he dedicated his life to the service of God from that moment.

Unfortunately, much of what people today think they know about Calvin is probably gained either directly from his writings, or indirectly through people such as Dave Hunt (particularly so) and David Cloud.  The source of at least some of the “untruths” may have originated from a vengeful converted monk (he later returned to the Catholic Church) who vilified Calvin in print.  “But Calvin’s theological certitude withstood many challenges and conflicts, including the trial of Jerome Bolsec, a former Catholic monk who had become a Protestant physician.  Bolsec vigorously countered Calvin’s doctrine of predestination – the very underpinning of his clerical and civil authority.  (Bolsec was banished and later wrote a slanderous and historically destructive biography of Calvin.) In 1553, as public support for Calvin again ebbed lower, his supporters were once again galvanised by the arrest, trial, and execution of Miguel Servetus, the infamous author of a book that discounted the more universally accepted and fundamental doctrine of the Trinity.  Servetus had been arrested when he travelled to Geneva, and was later burned at the stake, though Calvin appealed for a more humane execution” (Preface to “The Institutes of the Christian Religion” p. xiv).   

Even the online Catholic Encyclopedia says of Bolsec’s biographies of Calvin and Beza, “These works are violent in tone, and find little favour with protestant writers. Their historical statements cannot always be relied on”CATHOLIC ENCYCLOPEDIA: Jerome-Hermes Bolsec (

Calvin’s Own Testimony of His Conversion

An excellent discussion of Calvin’s conversion can be found on this link:

Microsoft Word – The Conversion of John Calvin (  The account below, which is a fraction of the wonderful and enlightening material, was taken complete from this website.  I highly recommend the whole article. 

“Precisely when Calvin’s conversion took place cannot now be ascertained. The energy that has been spent and the ingenuity exercised on this point have been more or less fruitless, because the events of his life between 1528 and 1533, the period of his first Christian activity, have never been precisely recorded. Calvin himself mentions no particular calendar month or year, and we must resist the temptation to play the game of date-fixing. Yet if the time is uncertain, the fruits are not. Nevertheless, of some circumstances surrounding his conversion we may be sure.

‘Every time that I looked within myself,’ he recalls, ‘or raised my heart to Thee, so violent a horror overtook me that there were neither purifications nor satisfactions which could in any way cure me. The more I gazed at myself the sharper were the pricks which pressed my conscience, to such a point that there remained no other solace or comfort than to deceive myself by forgetting myself. But because nothing better was offered me, I continued on the course that I had begun. Then, however, there arose a quite different form of doctrine, not to turn us away from our Christian profession but rather to bring it back to its proper source and to restore it in its purity, cleansed, as it were, from all filth. But I, offended by the newness of it, was scarcely willing to listen to a word of it and I admit that at the beginning I valiantly and courageously resisted it. For, as men are naturally obstinate and stubborn in maintaining the system that they have once received, I had to confess that all my life I had been nourished in error and ignorance. And there was one thing especially which kept me from believing these people, that was reverence for the Church. But after I had sometimes listened and suffered being taught, I realized that any such fear that the majesty of the Church might be diminished was vain and superfluous. And when my mind had been made ready to be truly attentive I began to understand, as if someone had brought me a light, in what a mire of error I had wallowed, and had become filthy, and with how much mud and dirt I had been defiled. Being then grievously troubled and distracted, as was my duty, on account of the knowledge of the eternal death which hung over me, I judged nothing more necessary to me after having condemned with groaning and tears my past manner of life, than to give myself up and to betake myself to Thy way…’ (Quoted in J.Cadier: The Man God Mastered. IVF. 1960. 40-I)”.

“A further recollection yields a less intense account of the same momentous experience. ‘God in his secret providence finally curbed and turned me in another direction. At first, although I was so obstinately given to the superstitions of the papacy, that it was extremely difficult to drag me from the depths of the mire, yet by a sudden conversion He tamed my heart and made it teachable, this heart which for its age was excessively hardened in such matters.’ (Op cit.59. See Calvin’s Preface to the Psalms. C.T.S. 4. 40)”.

Calvin’s Conversion (by William Wileman)

One of Calvin’s many biographers, William Wileman also describes Calvin’s conversion.  He describes the discussion between Calvin and his cousin, Robert Olivetan, which led to Calvin’s salvation and new birth.  He says, in part:

There are only two religions in the world’.  This appears to have been the sword-thrust from the lips of Olivetan which silenced his cousin.  He persisted in showing that one religion was invented by man, and consisted in the supposed merit of good works; and that the religion that came from God was wrought in the heart by God himself as its Author and Finisher.

In plain terms, he pleaded that salvation is entirely of grace, through faith, not of works, but the gift of God…..The arrow of conviction having thus been fixed in the heart and conscience of the young student, none but the same hand could draw it out.  Calvin could not comfort himself, nor would he accept comfort from his cousin.  But Olivetan did all he could to persuade Calvin to study the Scriptures…..God continued to show him more clearly every day that there was no salvation by the works of the law or by human merit; that the law could only curse him, and that his own works were defiled and dead.  Herein was the whole of the Reformation being enacted first in the soul of the Reformer.  It is ever so.

None but a saved sinner can preach salvation by grace; none but a crucified man can preach a crucified Christ.  ‘Every time I went down into myself’ he tells us of this conflict, ‘or raised my heart to God, so extreme a horror fell upon me that no purifications, no satisfactions, could cure me of it.  And the more closely I considered myself, the sharper were the goads that pressed my conscience, so that there remained no other comfort than to forget myself’….

…..In this trouble of soul, Calvin went to the Bible.  He opened, he read, he discovered.  As he continued to open the Word, it was opened to his renewed understanding.  As he read, it was read to him by its Author.  As he discovered its holy doctrines, they were applied to him by the hand that wrote them.  In them he learned this essential truth: ‘Neither is there salvation in any other name under heaven given among men, whereby we must be saved’.

At length the day dawned, and the darkness fled away.  As he read and looked away from self, he came to this: ‘But He was wounded for our transgressions; He was bruised for our iniquities; the chastisement of our peace was upon Him; and with His stripes we are healed’ (Isaiah 53:5).

By the application of this word he received the atonement, joyfully believing in Jesus.  ‘O Father’, he responded, ‘His sacrifice has appeased Thy wrath; His blood has washed away my impurities; His cross has borne my curse; His death has atoned for me!’

On that day salvation came to that heart (Luke 19:9), and the Reformation in France was begun

The entrance of God’s words gave light to Calvin, and lighted a candle that is burning to this day” (Kindle pages 14 – 17; emphases added).

Microsoft Word – The Conversion of John Calvin (

An article on how Calvin was converted (by J. H. Merle D’Aubigne)

“’THE kingdom of Christ is strengthened and established more by the blood of martyrs than by force of arms,’ said the doctor of Noyon one day. At this period he had occasion to experience the truth of the statement. One day in the year 1527, a man thirty-six years old, of good family — he was related to M. de Lude — of ecclesiastical rank, prothonotary, [or protonotary: chief clerk in some law courts] and holding several benefices, Nicholas Doullon by name, having been accused of heresy, stood in front of the cathedral of Notre Dame, while an immense crowd of citizens, priests, and common people were looking on. The executioner had gone in the morning to the prison, stripped the prothonotary of his official robes, and having passed a rope round his neck and put a taper in his hand, had conducted him in this guise to the front of the church of the Virgin. The poor fellow had seen better days: he had often gone to the palaces of the Louvre, St. Germain, and Fontainebleau, and mingled with the nobles, in the presence of the king, his mother, and his sister; he had also been one of the officers of Clement VII. The good folks of Paris, whom this execution had drawn together, said to one another as they witnessed the sad spectacle: ‘He frequented the king’s court, and has lived at Rome in the pope’s service’. Doullon was accused of having uttered a great blasphemy against the glorious mother of our Lord and against our Lord himself: he had denied that the host was very Christ.

The clergy had taken advantage of the king’s absence, and had used unprecedented haste in the trial. ‘He was taken the Thursday before,’ and four days later was standing bareheaded and barefooted, with the rope about his neck, in front of the metropolitan church of Paris. Everybody was listening to hear the apology he would make to the Virgin; but they listened in vain; Doullon remained firm in his faith to the last. Accordingly, the hangman again laid hands on him, and the prothonotary, guarded by the sergeants, and preceded and followed by the crowd, was led to the Greve, where he was fastened to the stake and burnt alive. fc195 The execution of a priest of some dignity in the Church made a sensation in Paris, especially in the schools and among the disciples of the Reform. ‘Ah,’ said Calvin subsequently, ‘the torments of the saints whom the hand of the Lord makes invincible, should give us boldness; for thus we have beforehand the pledge of our victory in the persons of our brethren.’ While death was thinning the ranks of the evangelical army, new soldiers were taking the place of those who had disappeared. Calvin had been wandering for some time in darkness, despairing of salvation by the path of the pope, and not knowing that of Jesus Christ. One day (we cannot say when) he saw light breaking through the obscurity, and a consoling thought suddenly entered his heart. ‘A new form of doctrine has risen up,’ he said. fc196 ‘If I have been mistaken… if Olivetan, if my other friends, if those who give their lives to preserve their faith are right… if they have found in that path the peace which the doctrines of the priests refuse me?’… He began to pay attention to the things that were told him; he began to examine into the state of his soul. A ray of light shone into it and exposed his sin. His heart was troubled: it seemed to him that every word of God he found in Scripture tore off the veil and reproached him with his trespasses. He shed floods of tears. ‘Of a surety,’ he said, ‘these new preachers know how to prick the conscience. fc197 Now that I am prepared to be really attentive, I begin to see, thanks to the light that has been brought me, in what a slough of error I have hitherto been wallowing; fc198 with how many stains I am disfigured… and above all, what is the eternal death that threatens me.’ A great trembling came over him; he paced his room as Luther had once paced his cell at Erfurth. He uttered (he tells us) deep groans and shed floods of tears. He was crushed beneath the weight of his sin. Terrified at the divine holiness, like a leaf tossed by the wind; like a man frightened by a violent thunderstorm, he exclaimed: ‘O God! thou keepest me bowed down, as if thy bolts were falling on my head.’… Then he fell at the feet of the Almighty, exclaiming: ‘I condemn with tears my past manner of life, and transfer myself to thine. Poor and wretched, I throw myself on the mercy which thou hast shown us in Jesus Christ: I enter that only harbor of salvation…. O God, reckon not up against me that terrible desertion and disgust of thy Word, from which thy marvellous bounty has rescued me.’

Following Olivetan’s advice, Calvin applied to the study of Scripture, and everywhere he found Christ. ‘O father!’ he said, ‘his sacrifice has appeased thy wrath; his blood has washed away my impurities; his cross has borne my curse; his death has atoned for me… We had devised for ourselves many useless follies… but thou hadst placed thy Word before me like a torch, and thou hast touched my heart, in order that I should hold in abomination all other merits save that of Jesus.’ Calvin had, however, the final struggle to go through. To him, as to Luther, the great objection was the question of the Church. He had always respected the authority of a Church which he believed to have been founded by the apostles and commissioned to gather mankind round Jesus Christ; and these thoughts often disturbed him. ‘There is one thing,’ he told the evangelicals, ‘which prevents my believing you: that is, the respect due to the Church. The majesty of the Church must not be diminished…. I cannot separate from it.’

Calvin’s friends at Paris, and afterwards perhaps Wolmar and others at Orleans and Bourges, did not hesitate to reply to him. ‘There is a great difference between separating from the Church and trying to correct the vices with which it is stained…. How many antichrists have held the place in its bosom which belongs to the pastors only!’ Calvin understood at last that the unity of the Church cannot and ought not to exist except in the truth. His friends, perceiving this, spoke openly to him against the Pope of Rome. — ‘Men take him for Christ’s vicar, Peter’s successor, and the head of the Church… But these titles are empty scarecrows. Far from permitting themselves to be dazzled by these big words, the faithful ought to discriminate the matter truly. If the pope has risen to such height and magnificence, it is because the world was plunged in ignorance and smitten with blindness. Neither by the voice of God, nor by a lawful call of the Church, has the pope been constituted its prince and head; it is by his own authority and by his own will alone… He elected himself. In order that the kingdom of Christ may stand, the tyranny with which the pope oppresses the nations must come to an end.’ Calvin’s friends, as he tells us, ‘demolished by the Word of God the princedom of the pope and his exceeding elevation.’

Calvin, not content with hearing the arguments of his friends, ‘searched the Scriptures thoroughly,’ and found numerous evidences corroborating the things that had been told him. He was convinced. ‘I see quite clearly,’ he said, ‘that the true order of the Church has been lost; that the keys which should preserve discipline have been counterfeited; that Christian liberty has been overthrown; and that when the princedom of the pope was set up, the kingdom of Christ was thrown down.’ Thus fell the papacy in the mind of the future reformer; and Christ became to him the only king and almighty head of the church.

What did Calvin then? The converted often believed themselves called to remain in the Church that they might labor at its purification; did he separate himself from Rome? Theodore Beza, his most intimate friend, says: ‘Calvin, having been taught the true religion by one of his relations named Pierre Robert Olivetan, and having carefully read the holy books, began to hold the teachings of the Roman Church in horror, and had the intention of renouncing its communion.’ This testimony is positive; and yet Beza only says in this extract that he ‘had the intention.’ The separation was not yet decided and absolute. Calvin felt the immense importance of the step. However, he resolved to break with Catholicism, if necessary, in order to possess the truth. ‘I desire concord and unity, O Lord,’ he said; ‘but the unity of the Church I long for is that which has its beginning and its ending in thee. If, to have peace with those who boast of being the first in the Church, I must purchase it by denying the truth… then I would rather submit to everything than condescend to such an abominable compact!’ The reformer’s character, his faith, his decision, his whole life are found in these words. He will endeavor to remain in the Church, but… with the truth.

Calvin’s conversion had been long and slowly ripening; and yet, in one sense, the change was instantaneous. ‘When I was the obstinate slave of the superstitions of popery,’ he says, ‘and it seemed impossible to drag me out of the deep mire, God by a sudden conversion subdued me, and made my heart obedient to his Word.’ When a city is taken, it is in one day and by a single assault that the conqueror enters and plants his flag upon the ramparts; and yet for months, for years perhaps, he has been battering at the walls.

Thus was this memorable conversion accomplished, which by saving one soul became for the Church, and we may even say for the human race, the principle of a great transformation. Then, it was only a poor student converted in a college; now, the light which this scholar set on a candlestick has spread to the ends of the world, and elect souls, scattered among every nation, acknowledge in his conversion the origin of their own. It was in Paris, as we have seen, that Calvin received a new birth; it cannot be placed later, as some have wished to do, without contradicting the most positive testimony. Calvin, according to Theodore Beza, was instructed in the true religion by Olivetan, before he went to Orleans; we know, moreover, that Calvin, either at Bourges or at Orleans, ‘wonderfully advanced the kingdom of God.’ How could he have done so if he had not known that kingdom? Calvin at the age of nineteen, gifted with a deep and conscientious soul, surrounded by relations and friends zealous for the Gospel, living at Paris in the midst of a religious movement of great power, was himself touched by the Spirit of God. Most certainly everything was not done then; some of the traits, which we have indicated after the reformer himself, may, as we have already remarked, belong to his residence at Orleans or at Bourges; but the essential work was done in 1527. Such is the conclusion at which we have arrived after careful study. There are men in our days who look upon conversion as an imaginary act, and say simply that a man has changed his opinion. They freely grant that God can create a moral being once, but do not concede him the liberty of creating it a second time — of transforming it. Conversion is always the work of God. There are forces working in nature which cause the earth to bring forth its fruit; and yet some would maintain that God cannot work in the heart of man to create a new fruit!… Human will is not sufficient to explain the changes manifested in man; there, if anywhere, is found something mysterious and divine.

The young man did not immediately make his conversion publicly known; it was only one or two of his superiors that had any knowledge of his struggles, and they endeavored to hide them from the pupils. They fancied it was a mere passing attack of that fever under which so many people were suffering, and believed that the son of the episcopal secretary would once more obediently place himself under the crook of the Church. The Spanish professor, who came from a country were fiery passions break out under a burning sky, and where religious fanaticism demands its victims, had doubtless waged an implacable war against the student’s new convictions; but information in this respect is wanting. Calvin carefully hid his treasure; he stole away from his companions, retired to some corner, and sought for communion with God alone. ‘Being naturally rather wild and shy,’ he tells us, ‘I have always loved peace and tranquillity; accordingly I began then to seek for a hiding-place and the means of withdrawing from notice into some out-of-the-way spot.’ This reserve on Calvin’s part may have led to the belief that his conversion did not take place until later.

The news of what was passing in Paris reached the little town in Picardy where Calvin was born. It would be invaluable to possess the letters which he wrote to his father during this time of struggle, and even those of Olivetan; but we have neither. John’s relations with Olivetan were known at Noyon; there was no longer any doubt about the heretical opinions of the young cure of St. Martin of Motteville… What trouble for his family, and especially for the episcopal notary! To renounce the hope of one day seeing his son vicar-general, bishop, and perhaps cardinal, was distressing to the ambitious father. Yet he decided promptly, and as it was all important for him that Calvin should be something, he gave another direction to his immoderate thirst for honors. He said to himself that by making his son study the law, he would perhaps be helping him to shake off these new ideas; and that in any case, the pursuit of the law was quite as sure a road, and even surer, to attain to wealth and high station. Duprat, at first a plain lawyer, and afterwards president of the parliament, is now (he thought) high chancellor of France, and the first personage in the realm after the king. Gerard, whose mind was fertile in schemes of success for himself and for others, continued to build his castles in the air in honor of his son; only he changed his sphere, and instead of placing them in the domain of the Church, he erected them in the domain of the State.

Thus, while the son had a new faith and a new life, the father had a new plan. Theodore Beza has pointed out this coincidence. After speaking of Calvin’s vocation to the ecclesiastical profession, he adds that a double change, which took place at that time in the minds of both father and son, led to the setting aside of this resolution in favor of another? The coincidence struck Calvin himself, and it was he no doubt who pointed it out to his friend at Geneva. It was not therefore the resolution of Gerard Cauvin that decided his son’s calling, as some have supposed. At the first glance the two decisions seem independent of each other; but it appears probable to me that it was the change in the son which led to that of the father, and not the change in the father which led to that of the son. The young man submitted with joy to the order he received. Gerard, by taking his son from his theological studies, wished to withdraw him from heresy; but he was mistaken. Had not Luther first studied the law at Erfurth? Did not Calvin by this same study prepare himself better for the career of a reformer, than by the priesthood?

Conversion is the fundamental act of the Gospel and of the Reformation. From the transformation effected in the individual the transformation of the world is destined to result. This act, which in some is of very short duration and leads readily to faith, is a long operation in others; the power of sin is continually renewed in them, neither the new man nor the old man being able, for a time, to obtain a decisive victory. We have here an image of Christianity. It is a struggle of the new man against the old man — a struggle that has lasted more than eighteen hundred years. The new man is continually gaining ground; the old man grows weaker and retires; but the hour of triumph has not yet come. Yet that hour is certain. The Reformation of the sixteenth century, like the Gospel of the first (to employ the words of Christ), ‘is like unto leaven, which a woman took and hid in three measures of meal, until the whole was leavened.’ (Matthew 13:33) The three great nations on earth have already tasted of this heavenly leaven. It is fermenting, and soon all the ‘lump’ will be leavened”.
