Peterans are cerebral and seem to practice a form of mysticism, often praying for answers and writing down religious texts and tracts. The faith is rather informal priests often use humor in scheduled sermons and tend to engage in impromptu public sermons and evangelizing.
The Peteran branch believe the Watcher to be a compassionate and loving god who wants Sims to have happiness. Jacoban clothing and buildings are grand, especially their cathedrals. Getting Sims to submit to this code and fear punishment by the Watcher enough to want to be absolved is the main goal of Jacoban priests. The Jacoban branch believes the Watcher to be an angry, vengeful god and claims that Sims must live by strict moral code to avoid punishment.
Either way, it has split into two named branches, mirroring medieval Christianity and its schism into Catholicism and Protestantism. The religion is monotheistic, centered around the worship of 'The Watcher.' The name of the religion as a whole is unknown it may not even have one. Though pagan worship is briefly touched on, only belief in the Watcher (in a faith that is very similar to Christianity) is elaborated on.
