Hi everyone. Some churches, such as the Mormon church and other restorationist churches accept the Great Apostasy theory as valid. They say that the Catholic Church was not started until the 3rd or 4th centuries. How does one refute this idea? 
I have a feeling that quoting early Church fathers such as the one in my signature would be valuable in this debate but what about others? How can we prove that the Church was indeed Catholic from the very beginning?
