One of the leaders of the Reformation, John Calvin, was particularly influenced by the Renaissance philosophy of humanism. Why were so many Europeans willing to accept this new way of looking at life during 15th and 16th centuries?

The Catholic Church decided to place more emphasis on the rights and authority of the individual, rather than Church authorities.
The philosophy of humanism suggested a way of life that allowed humans to do whatever they wanted, regardless of the consequences.
After the Black Death, Europeans began to question the social order and the authority of Church teaching.
Humanism was seen as a way to escape poverty since each person could focus on finding money and resources for himself.
