Question

Why did John Calvin write the Institutes of the Christian Religion?

Answer 1

The institutes of the Christian religion were written by John Calvin, in order that all knew the reason for the reform and the Protestant doctrine for the time of Martin Luther, when it was raised against the traditional Christianity and Catholic, these were the right causes Which led John Calvin to write and reinforce his religious belief and to carry the message to all.

Answer 2

I believe the answer is: to explain the Reformation and Protestant beliefs

The reformation was made due to the corrupt practices that the catholic churches made at the time (selling indulgences and being too involved in pursuit of government powers).

Because of this, many christian feel that separation from the catholic church is necessary because it contradict their religious belief, this led to the reformation and development of protestant beliefs.
