Okay, take two on what I posted a while ago; to add more flavour to the Evangelical's, I have been coding a few events
The Evangelical Reformation
Evangelicalism is described as a faith where the doctrinal divisions that used to exist in Pre-Event Protestantism have been set aside in the face of the post-deluge world. Part of this was the establishment of the Ecumenical Council's, with its seats in Atlanta, Chapel Hill, Washington, St Louis and Chicago. However, only the first two remain at the time of the games start. This flexibility in doctrine, once a feature and strength, becomes a weakness in the face of heresy
After an amount of time (50-100 years maybe, though I've been testing it with the year 2667), an event fires about a monk who has discovered a document on the ancient Westphalia Treaty, and from there they write a document claiming that the Emperor's subjects have the right to choose whatever religion they wish. Heretic priests, such as Charismatics, use this to start preaching that they have the right to pick whatever faith they wish. Wanting to stop it, the Emperor holds a council in Augusta; but instead of calming things, the council results in the monk's words spreading even further, resulting in a massive hit to moral authority.
From there, various events would follow on; counts and duke's choosing to convert to different heresies of the Evangelical faith (I'd want to add at least 3 more to break up the amount of Charismatic's appearing, so there's less chance they'll become the new orthodoxy), revival meetings for both heresies and Evangelicalism, etc. Alongside this, I'd add it so that all of the heresies have a variety of events and abilities that Evangelicalism doesn't have-Charismatic's could have ceremonies where they can gain either good traits or become possessed, Antinomian's would get less negative opinion from bad traits such as Lustful (if possible), etc.
However, none of the heresies would be able to remove the proliferation of heresy-possibly not even be able to hold the title of Holy Columbian Emperor-which an Evangelical Emperor would be able to choose by decision; after gaining a large amount of piety, and retaking all five seats of the Evangelical Convention, the Emperor would be able to create a new Imperial church, where the Patriarch of Atlanta would hold power as the Primate of the Imperial Church (name? not sure); they'd have a variety of new abilites, such as being able to excommunicate, call for crusades, etc.
I've coded some of this, but some of those files have disappeared on my broken hard drive, so if people are interested I'll do my best to keep coding the events.
