The Oracle and the Temple : From Medieval Geomancy to the Ifa Church (Nigeria, Benin)

How does an oracle become a church? In Nigeria in the early 1930s, the African Church of Ifa was founded by Adebanjo Olorunfunmi Osiga, who combined the doctrinal, moral, and ritual foundations of Anglican Christianity, which he converted to in his youth, with precolonial Yoruba beliefs and the medieval practice of divination through geomancy to create a new form of worship. The Oracle and the Temple traces the unexpected journey of these ideas and practices across centuries and continents. Drawing on years of fieldwork in Benin and a remarkable collection of primary sources (including eight by Osiga), author Erwan Dianteill reveals how a system of divination became a structured religion with its own clergy, liturgy, and moral code. In addition to Sunday services in a temple, diviners claiming to speak for the god of Destiny (Fa or Ifa) deliver oracles to guide the faithful in their private lives. These practices, while combining to form a whole religion, remain distinct in terms of time and space, with temple and oracle functioning parallel to each other. Rigorous yet accessible, The Oracle and the Temple illustrates how African diviners engaged with Christianity, writing, and institutions to transform inherited practices without abandoning their cosmological foundations. The result is a compelling account of religious creativity, where tradition is not preserved without change, but reworked into new, enduring forms.
