The Wafipa, as with most Africans, had a supreme god: Umweele, the creator of ultimate power in the world. There was, however, no cult to this god, although it was common for those needing help to utter "Umweele, forgive me". Worship was also directed to lesser and closer divinities, the most important and terrible being Katai, said to be the enemy of domestic animals and the bringer of smallpox and other diseases. Katai could come as a dog with shining eyes, in dreams; a mouse in a hut corner; a beautiful youth; or even smoke (the African concept of deities included the souls of animals, spirits, and humans being interchangeable).
