John Calvin played a very important part in the Catholic Counter Reformation. He was born in Noyon, France 10 July 1509.
He studied theology as a teen but his dad made him study law later on. When his dad died he then went back to studying theology.
What shall I study?
Law or Theology?
Later on in life, he went through a sudden conversion from Roman Catholic to Protestant, as he thought that this was God's will.
He then started to rebel against the Roman Catholic Church. He wrote the Institutions of the Christian Religion, which told what was wrong with the Roman Catholic Church. He also taught a doctrine called Predestination, which was belief that God ordained everything.
He went to Geneva to try to get Geneva to support Protestantism priests. He failed then travelled to Strasbourg to give out sermons to his followers. In 1541 he was invited to Geneva and added to the city council.
After making 6 copies of the Institutions of the Christian Religion, he died in 1564 at the age of 54 after many health problems.
