The Meaux Circle was formed by a group of humanists including Jacques Lefèvre d’Étaples and Guillaume Briçonnet, bishop of Meaux, in the effort to reform preaching and religious life. The Meaux circle was joined by Vatable, a Hebraist, and Guillaume Budé, the classicist and librarian to the king. Lefèvre's works such as the "Fivefold Psalter" and his commentary on the Epistle to the Romans were humanist in approach. They put emphasis on the literal interpretation of Scripture and highlighted Christ. Lefèvre's approach to the Scriptures influenced Luther's methodology on biblical interpretation. Luther would later use his works in developing his lectures that contained ideas that would spark the greater part of the Reformation known as Lutheranism. William Farel also became part of the Meaux circle. He was the leading minister of Geneva who invited John Calvin to serve there. They were later exiled out of Geneva because they opposed governmental intrusion upon church administration. But their eventual return to Switzerland was followed by major developments in the Reformation that would later grow into Calvinism. Marguerite, Queen of Navarre, the sister of King Francis I and mother of Jeanne d'Albret, also became part of the circle.
