The Greek Constitution recognises Eastern Orthodoxy as the 'prevailing' faith of the country, while guaranteeing freedom of religious belief for all. The Greek government does not keep statistics on religious groups and censuses do not ask for religious affiliation. According to the U.S. State Department, an estimated 97% of Greek citizens identify themselves as Eastern Orthodox, belonging to the Greek Orthodox Church, which uses the Byzantine rite and the Greek language, the original language of the New Testament. The administration of the Greek territory is shared between the Church of Greece and the Patriarchate of Constantinople.
