On Today in Church His-Story (Episode 29) we look back to the closing of the Council of Nicaea, which occurred on this day, July 25, 325. Some historians say it was August 25. Nobody is for certain. What is for certain, however, is what took place at Nicaea. A creed affirming the orthodox view of the doctrine of the person of Christ was established in this first ecumenical council. On this episode, we consider the influence of three men in particular: Origen, Constantine, and Athanasius. This council changed history. Athanasius’ stand changed history. We learn that it was also one letter of one word that also changed history.
