The Devil Walked Into The Church and Nobody Noticed!

During the time of the Protestant Reformation there were many Christians who were persecuted, tortured and put to death for standing against the teachings and the FALSE gospel of the Roman Catholic Church. That same Catholic Church still teaches the very same things in our modern day that they did back then. Did the Protestant reformers seek to have UNITY with the Church of Rome back then? Of course not and that is why the Church of Rome came against them, and killed multitudes of them also. So if the Church of Rome is still preaching the same damnable heresies, why are the leaders in the modern day church joining in UNITY with them?
