Which Came First??

The Council of Trent may have been in part brought about in response to Martin Luther. Yet actions of the Catholic Reformation were in progress before Luther was even conceived as a threat to the Catholic Church. This can be seen as starting under Pope Alexander. Though under pope Alexander during the renaissance a reform group was conceived it had little to no observable effect on any of the issues plaguing the church at the time. Yet the reform process was expedited by Luther’s criticism of the Catholic church although many loyal Catholics did agree with Martin Luther that there were issues that needed to be fixed within the church. These loyal followers instead brought about the Council of Trent to solve the issues that they saw needed clarification. Also the Council of Trent condemned the protestant movement.
