Condemning the Heretics and their Heresies A) The Council of Nicaea (AD 324) - was called by Constantine to consider and, if possible, settle the Arian heresy. It gave the church the first great ecumenical creed. B) The First Council of Constantinople (AD 381) - called by Emperor Theodosius the Great to correct errors of Apollinarianism and Macedonianism. C) The Council of Ephesus (AD 431) - was presided over by Cyril, Bishop of Alexandria, and was called to deal with Nestorianism. D) The Council of Chalcedon (AD 451) - three bishops and two presbyters presided. They were representatives of Leo of Rome. E) The Council condemned Eutychianism, and gave the church the credal statement on Christology which has stood the test of the centuries. F) The Chalcedonian statement has largely become the orthodox creed or Protestantism. G) The Second Council of Constantinople (AD 680) - was called by the Emperor Constantine Pogonatus, and was directed against Monothelitism. H) The Frankford Synod (AD 794) - was called by Charlemagne and at it, ADOPTIONISM was condemned. Conclusion: One can easily see, by comparing the ancient and contemporary heresies, just how Satan has constantly tried to hide and corrupt the true theanthropic nature of Christ. If either nature is ‘corrupted’, true salvation is then destroyed!
