This event, from 403 CE. Specifically, what if John Chrysostom remained Patriarch of Constantinople until a later death (sometime 415-420), while Theophilus is removed from his post as Bishop (or "Pope") of Alexandria, which also prevents his nephew Cyril from succeeding him.
How does this change the history of the church in the early 5th Century? For example, do the disputes floating around this time (what OTL calls Nestorianism, Monosophytism, etc) still lead to a Council? And without Cyril playing an active role, does this alternate Ephesus play out differently? Does the absence of Archbishop Atticus change this period as well?
