The majority of Papua New Guinea’s people are at least nominally Christian. More than two-fifths of the population is Protestant; Lutherans make up the largest portion of those, and there are some Anglicans and a growing number of Pentecostals. Approximately another one-fifth are Roman Catholics. Seventh-day Adventism is increasing in popularity, and there are also small numbers of Bahāʾīs and Muslims. Despite the apparent inroads made by introduced religions, much of the population also maintains traditional religious beliefs, and rituals of magic, spells, and sorcery are still widely practiced.
