Indigenous religions, varying widely in ritual and belief, remain important in tribal societies in Papua New Guinea, with about 34% of the population practicing some form of traditional belief either exclusively or in conjunction with another faith. However, most of the population is nominally Christian. Of these, about 22% are Roman Catholics; 16% are Lutheran; another 8% are Presbyterian, Methodist, or London Missionary Society; 5% are Anglican; 4% Evangelical Alliance; and 1% Seventh-Day Adventist. Other Protestant sects account for 10% of the population. Baha'ism is the only other nonindigenous faith that has gained a foothold. The Muslim community maintains a mosque in Port Moresby.
