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.
