What is predestination?
God knows who will be saved. You cannot do anything to change your destiny.
Why should you follow Calvin?
John Calvin gives us a mission and discipline that the Catholic Church does not offer. We need to focus on scripture and predestination.
Why do we need a reform?
The Church is taxing the poor and the middle class more than before. The money is going to the construction of unnecessary churches. The Church is also selling indulgences to pay off the time you spend in purgatory. People need to do their time and they need consequences for their actions.
