Religion
Virtually the entire population is Sunni Muslim; Christians constitute most of the rest, of whom two-thirds adhere to the Greek Orthodox church. Other Christian groups include the Greek Catholics, also called the Melchites, or Catholics of the Byzantine rite, who recognize the supremacy of the Roman pope; the Roman Catholic community, headed by a pope-appointed patriarch; and the small Syrian Orthodox Patriarchate of Antioch, or Syrian Jacobite Church, whose members use Syriac in their liturgy. Most non-Arab Christians are Armenians, and the majority belong to the Gregorian, or Armenian, Orthodox church, while the rest attend the Armenian Catholic Church. There are several Protestant denominations representing communities whose converts came almost entirely from other Christian sects.
The Druze, an offshoot of the Ismāʿīlī Shīʿite sect, number a few hundred and reside in and around Amman. About 1,000 Bahāʾī—who in the 19th century also split off from Shīʿite Islam—live in Al-ʿAdasiyyah in the Jordan Valley. The Armenians, Druze, and Bahāʾī are both religious and ethnic communities. The Circassians are mostly Sunni, and they along with the closely related Chechens (Shīshān)—a group numbering about 1,000, who are descendants of 19th-century immigrants from the Caucasus Mountains—make up the most important non-Arab minority.
