Institutes of the Christian Religion
John Calvin, a Frenchman, escaped from the persecution to Basle, Switzerland, where he published the "Institutes of the Christian Religion" in 1536. In the same year, he visited Geneva, but was forced out for trying to reform the church. When he returned by invitation in 1541, he wrote the "Ecclesiastical ordinances", the constitution for a Genevan church, which was passed by the council of Geneva.
