From the time Emperor Constantine called the Council of Nicea in 325 AD, Roman Emperors had serious interest in church business. Pelagius, the original “anti-calvinist,” was a theologian who believed that mankind had free will to choose to accept Christ as their Savior or reject Him entirely. On April 30, 418, Roman Emperor Honorius banned all Pelagians from Rome, considering them a threat to the Empire’s peace.
