John Calvin (1509-1564) was a French theologian and religious reformer who played a pivotal role in the Protestant Reformation. Born in Noyon, France, he initially studied theology and law in Paris.
After a religious conversion, he embraced Protestantism and fled to Basel, Switzerland, where he published his seminal work, “Institutes of the Christian Religion,” which became a cornerstone of Reformed theology.
Calvin’s ideas and leadership were instrumental in shaping the Reformed tradition, emphasizing doctrines such as predestination and the sovereignty of God.
He briefly served in Geneva, Switzerland, as a reformer, where he established a theocratic government and implemented a strict moral and religious code. Exiled from Geneva for a time, he continued his theological work in Strasbourg.
Calvin was eventually invited back to Geneva and continued his reform efforts, solidifying the city as a hub for Reformed Protestantism. He authored numerous commentaries on the Bible and theological treatises, leaving a lasting impact on Christian theology.
He passed away in Geneva in 1564, but his theological legacy, known as Calvinism, has profoundly influenced Protestantism and Christian thought worldwide.

The “Institutes” became a foundational text of Reformed theology and went through several expanded editions throughout Calvin’s life.

1536 – Visits Geneva and becomes involved in the Reformation movement there
In the same year he published the first edition of the “Institutes,” Calvin made a brief stopover in Geneva while en route to Strasbourg.
During his stay, he was invited by Guillaume Farel, another Protestant reformer, to assist in the reform efforts in Geneva. Calvin reluctantly agreed and began working alongside Farel to advance the cause of the Reformation in the city.
1538 – Banished from Geneva
Calvin’s efforts in Geneva faced significant opposition, particularly from the city council. His strict moral and religious reforms were not well-received by some of the residents.
In 1538, Calvin and Farel were exiled from Geneva due to the tensions and conflicts surrounding their reform efforts. Calvin moved to Strasbourg, where he continued to write and teach.
1541 – Invited back to Geneva and establishes a theocratic government
In 1541, John Calvin was invited back to Geneva by the city council, which had undergone a change in leadership and was more receptive to Calvin’s vision for a reformed church and society.

Under his leadership, Geneva became a center of Reformed Protestantism and a model for other Reformed communities.
1549 – Publishes commentary on the Book of Psalms
Calvin was not only a theologian but also a prolific writer and biblical commentator. In 1549, he published his commentary on the Book of Psalms.

Throughout his life, Calvin continued to revise and expand his “Institutes of the Christian Religion.” The final Latin edition was published in 1559, and it represented the culmination of his theological thought and contributions.
