Religion in Cuba reflects the island’s diverse cultural elements. Cuba is traditionally a Catholic country. In some instances Catholicism is much modified and influenced through syncretism. A common syncretic belief is Santería, which originated in Cuba and spread to neighboring islands; it shows similarities to Brazilian Umbanda and has been receiving a degree of official support.
The Roman Catholic Church estimates that 60 percent of the population is Catholic. Membership in Protestant churches is estimated to be 5 percent and includes Baptists, Pentecostals, Jehova’s Witnesses, Seventh-day Adventists , Presbyterians, Anglicans, Episcopalians, Methodists, Religious Society of Friends (Quakers), and Lutherans. Other groups include the Greek Orthodox Church, the Russian Orthodox Church, Muslims, Jews, Buddhists, Baha'is, and Mormons. The remainder of the population is either non-practicing of any particular religion, atheist, or agnostic.
