The correct answer to this open question is the following.
John Calvin felt it necessary to establish a theocracy because he wanted the city to be controlled by the clergy because he considered it had the authority and knowledge to rule.
John Calvin (1509-1564) was a French clergyman and theologian that was part of what historians called the second generation of Protestants reformers in Europe. Some scholars think he followed up the reformation steps of German monk Martin Luther, and in 1536, published the important work "Institutes of the Christian Religion."
