If people have some understanding, they know the roots of Calvinism lays with Augustine at the beginning of the fifth century. It should be mentioned that all the church fathers before him believed in free will. Origin (4th Cent) for example, had sprawling debates with the Gnostics concerning this topic. But the church fathers who were handed the church directly from the apostles also believed in it. Why wasn't Augustines election and Limited Atonement taught earlier? Clement of Rome, Justin Martyr, Polycarp, Ignatious, all of them believed in free will. What are the chances that ALL of the church fathers that were handed the church from the Apostles wouldn't have been told about this and then yet still, the church fathers that followed them, such as Tatian of Syria, Irenius and Mathetes? Augustine developed this thought. It is certainly his whether through the Holy Spirit or not. Even then, the church didn't except his theology in its entirety. They NEVER excepted the theology of no free will. Calvinism as you know it, wasn't developed until the 16th century, IT'S PRACTICALLY A NEW THOUGHT! I don't believe this puts Calvinism in its grave but it does represent a nail and a couple shovels of dirt. I would have thought at least ONE church father extented from the apostles would have known this theology instead of believing in free will. Perhaps one of the next generation after that, but nothing.
