Community Beliefs and Practices

People are Christian or have indigenous beliefs, but often they have a mixture of the two, called "syncretic."

In this society, it's less about how educated you are and more about how much money you have. Religion, at least in Tambudzai's family was a mixture of indigenous beliefs until Babamukuru became Christian. At this point, he forced Tambudzai's parents to have a formal, Christian wedding. Money is a controlling factor, not so much a god or some deity.
