The Council of the Godly.
The Council consists of the senior, members of the 'official' religions of Porter's Bar - The Arthians, The Yamarans, Shannans, The Wenans and the Royal Ancestor Worshippers. It consists of the heads of each of the Temples in the city, as well as the heads of the Ordaire Paupaire and the Brothers of Small Mercy and is chaired by the Patriarch. This means that the Arthians have a larger representation that the other religions on the council..
The council only meets occasionally, and then always for a specific purpose. The most important meeting is to appoint or recall a Patriarch. Patriarchs can be elected by a straight majority, although the council normally work for a compromise. This generally means the Arthian seen as most sympathetic to the other religions is elected. To recall a Patriarch requires a unanimous decision by the rest of the council. Once elected the Patriarch holds office for life [unless recalled]. S/he vacates their position as head of an establishment and moves into the Patriarch's house, and the establishment chooses a new leader (by whatever means they use) to replace him/her on the council. The Patriarch chairs the council but doesn't vote - although s/he has the casting vote should there be a tie.
The council is also convened to 'approve' other religions. If different religion wants to establish a shrine[1] in the city, they need the permission of the council to do so. This is generally granted unless the religion is seen to conflict with the values of any of the established religions, or is liable to endanger the city. Religions that insist that their god is the one and only god are automatically refused permission. There are 3-4 shines of various religions dotted around the city, these include the Brethren of the Road (a sect who runs a hostel for travellers and worship Ptah), and a shrine to the Dwarven Pantheon, as worshipped at Baraduum.
Once a religion has been established in the city for a while, they can apply to the Council of Churches to build a temple[2]. With this permission comes full recognition within the city and a seat on the Council of the Godly. So far this permission has only been granted to the four main religions of the city.
Priests of recognised temples and shrines are automatically treated as citizens of Porter's Bar.
