The first missionaries to proselytize in Namibia were British Congregationalists and Methodists; German and Finnish Lutherans and German-speaking Roman Catholics followed. As a result, more than 90% of Namibians are Christians, with the largest denominations being Lutheran and Roman Catholic. Other principal denominations, include Baptist, Methodists, and the Church of Jesus Christ of Latter-Day Saints. Some indigenous religious customs have survived. Nearly 10% of the population practices indigenous religions, primarily among the ethnic tribes. One notable custom is the ritual fire, which some tribes keep burning continuously to ensure life, fertility, prosperity, and the happiness of ancestors. There are small numbers of Jews, Muslims, Buddhists, and Baha'is in the country.
