Jacob Vernet
Jacob Vernet (1698–1789) was a leading theologian in Geneva who promoted a rational, moderate approach to religion. He was known as one of the most important Genevan pastors of his day.
Vernet studied under the theologian Jean-Alphonse Turrettini and became a pastor in 1722. That year he went to Paris to tutor for a wealthy family and spent nine years there talking with French philosophers. In 1728 he traveled to Italy and Holland, meeting scholars like Lodovico Muratori, Montesquieu, and the economist John Law, and he engaged with other thinkers in Holland.
He returned to Geneva in 1730 to pastor in Jussy and tutored Turrettini’s son, taking him on a tour through Switzerland, Germany, Holland, England, and France in 1732. In Marburg he met the philosopher Christian Wolff, who inspired Vernet to value moderation. His four months in England impressed him with the country’s religious moderation and political freedom.
Back in Geneva, Vernet became pastor of the churches of St. Pierre and St. Gervais in 1734, and he was named rector of the academy in 1737. He later taught belles lettres (1739) and theology (1756). He was well connected with Geneva’s government and, in 1734, published a work praising the patrician rulers of the city and their wise finances. He believed that people did not need to control the government as long as power was in good hands.
Vernet met Voltaire in Paris in 1733 and corresponded with him about Voltaire’s works in Geneva. When Voltaire moved to Geneva in 1754, they argued on several points, and the city’s officials helped keep the dispute peaceful. Vernet also helped D’Alembert with materials about Geneva when D’Alembert worked on an encyclopedia article about the city. Rousseau wrote to Vernet in 1754 about being readmitted to the Geneva church and later praised Rousseau’s view that a state constitution links many things together. Their disagreements grew, and Rousseau’s Contrat Social and Emile (1762) were condemned in Geneva with Vernet’s support.
Vernet’s thinking was influenced by Descartes, English moderation, and Arminian theology. He sought a middle way between extremes and believed religion should be reasonable. He followed Turrettin’s approach of using faith that could be acceptable to both the pious and those who doubted. He refused to speculate about mysteries like predestination, reprobation, or the Trinity.
His major work included a French edition of Turrettin’s Latin theses on Christian religion, showing that faith can go with reason. He also argued that even a “heathen in Africa” could be saved if he responds to God’s revelation in nature and conscience. Vernet taught that God wants people to obey and do good of their own free will, and that virtue is reachable by everyone.
In his brief guidance for teaching faith, called Instruction chretienne, he aimed to present a simple, clear view of Christianity to reduce disagreements among Christians. He disliked overly precise Reformed scholasticism, believing true religion should lead to honoring God and to personal happiness. While he did not think religious choice was unimportant, he argued that Christianity stood on reasonable grounds.
