John Calvin’s influence on the Reformation extended beyond his theological writings; he was also instrumental in training the next generation of Protestant ministers. Recognizing the urgent need for well-trained clergy who could effectively spread and defend Reformed theology, Calvin established a training school for ministers in Geneva. This institution became a crucial center for theological education, equipping Protestant leaders with the knowledge and skills needed to lead churches, preach the gospel, and resist Catholic persecution.

One of the most significant groups to pass through this school was the French Huguenots—French Protestants who faced severe persecution under the Catholic monarchy. Many Huguenot refugees who had fled France sought refuge in Geneva, where they found a safe haven under Calvin’s leadership. Geneva, by this time, had become a hub for Protestant activity, and Calvin’s training school became a vital institution in the survival and spread of Reformed Christianity. Countless French Huguenots trained under Calvin’s guidance before covertly slipping back into France to establish underground congregations. These secret churches operated under constant threat of discovery, yet they played a crucial role in the spread of Protestantism within France.

Calvin’s vision for this school extended beyond just training pastors. He sought to develop an educated clergy who would be well-versed in both theology and classical studies, ensuring that they could engage in intellectual debates and defend Protestant beliefs against Catholic arguments. The curriculum was rigorous, focusing on biblical studies, theology, Latin, Greek, Hebrew, and philosophy. This strong emphasis on education helped create a highly literate and disciplined group of Protestant leaders who would go on to spread Calvinist doctrine throughout France, the Netherlands, Scotland, and other parts of Europe.

Over time, this training school grew in prestige and influence. In 1559, it was formally reorganized and expanded, eventually becoming known as the University of Geneva. Under Calvin’s leadership, it not only trained ministers but also developed into a respected academic institution, attracting students and scholars from across Europe. The University of Geneva became a center for Reformed thought, shaping the intellectual and religious landscape of Protestant Europe.

The impact of Calvin’s training school was profound. Many of the ministers who studied there played pivotal roles in the spread of Protestantism, particularly in France, where their underground churches laid the groundwork for what would become a sustained Huguenot movement. Despite intense persecution, the teachings of Calvin and his ministers continued to spread, influencing Protestant movements in Scotland (through John Knox), the Netherlands, England, and beyond.

By establishing this school, Calvin ensured that Reformed theology would not only survive but thrive, carried forward by a new generation of ministers who would continue his work long after his death. The University of Geneva remains a lasting testament to his commitment to education, religious reform, and the defense of Protestant beliefs in the face of opposition.
