Overview of Religion in Kenya
The Stats
Approximately 70% of Kenyans are Christians (38% Protestant, 28% Catholic); about 25% are adherents of indigenous religions; 6% are Muslim. Among the Asian community there are Hindus, Sikhs, Parsees, and Bahais.
Indigenous Beliefs
Although traditional beliefs and practices vary in detail among Kenya's ethnic groups, they share many general characteristics. Almost all involve belief in an eternal, omnipotent creator envisaged as remote from men. The Kikuyu's god is named "Ngai”. Ngai cannot be seen, but is manifested in the sun, moon, thunder and lighting, stars, rain, the rainbow and in the great fig trees that serve as places of worship and sacrifice. Many indigenous religions also recognize spiritual forces at work in the world that are closer to the living and more involved in their daily affairs. If men and women please the spirits, success is assured; if they incur the spirits' anger, illness or evil may occur. For many indigenous believers, ghosts form a distinct category of ancestral spirits are thought to return to seek revenge on the living. Beliefs in sorcery and witchcraft play important roles in many indigenous belief systems and often persist after conversion to Christianity or Islam even when other elements of traditional religions have faded.
Christianity
Christian missionary activity began in Kenya's hinterland when its interior was opened to rail travel between Mombasa and Uganda at the end of the nineteenth century. Churches were founded in the 1920s and 1930s, especially in areas where Kikuyu, Luo, and Luhya predominated, some of which sought to combine Christian and indigenous beliefs. Most churches tended to be ethnically homogenous since colonial authorities maintained a policy of allocating a mission to a particular territory, though this tendency has changed with increasing communication and mobility. In Kenya there are also several independent Christian churches that have broken ties with other Christian or Protestant denominations. In Kenya today there are still many mission churches. Many worldwide religious groups have a strong presence.
Islam
Over half of Kenya's Muslim minority is of Somali origin. The remainder is largely made up of Galla-speaking peoples and the Swahili-speaking community on the coast, which has maintained uninterrupted contact with Muslims from the Arabian peninsula since the fourteenth century. Most Bajun are Muslims, as are some members of the Mijikenda and Pokomo groups.
