The Reformed movement was complex and variegated during this period, but the French reformer of Geneva John Calvin was arguably the most influential Reformed theologian of his time and his impact was long-lasting. His "Institutes of the Christian Religion" was widely distributed and considered by some to be the most important work of theology of the era. The Genevan Consistory, a church council made up of lay and clergy members who was given power to enforce morals legislation and excommunicate citizens, became a dominant force in everyday life. This relative ecclesiastical independence from civil authority was a rare achievement and considered by many to be the Reformed ideal.
