The dominant religion on Zannqu centers around a wrathful god who sent her Holy Daughter, Jessia, to die for the sins of the world (and so the Holy Mother no longer had to deal directly with her believers). The current religious schism, which has so far only gone as far as some large, mostly nonlethal street brawls in some of the cities, centers around whether worshipers can speak directly to the Holy Daughter or must use a priest as an intermediary.
At present planetary security has managed to contain the two sects with minimal violence, but there are concerns of more radical elements on each side taking things further.
