Class V Churches minister beginning and intermediate religious services  and have the authority to train and ordain ministers. These Churches are  so named because the highest level of training they provide is  designated Class V (five) within the progression of Scientology  religious services. Class V Organizations provide auditing through  Clear. Also called Central Organizations, these Churches are fully  responsible for all Scientology activities in their respective zones and  are much larger than field groups and missions. They are hubs for their  community of Scientologists. They are places where Scientologists from  all walks of life may gather to share common experiences and plan and  coordinate and implement all manner of humanitarian initiatives.  Scientologists also attend their Churches to participate in auditing and  training as well as Sunday services, weddings, funerals, and naming ceremonies, regular Friday evening graduations and the celebration of Scientology holidays.
