Tempels founded the Jamaa movement as a demonstration of ontology-based evangelization

Evidence

The book attempts to establish a new way of evangelizing the Luba people, a way that takes seriously Bantu ontology. It is in that light that the Jamaa group or movement that Tempels founded is to be understood. It was supposed to be a showcase of how new evangelization could be done and how African resistance against Christianity could be addressed. — Frans Dokman, Beyond Bantu Philosophy_…, 165

• XREF: The Jamaa movement and its later course is a known controversy in Bantu philosophy debate; worth verifying against other sources.
• QUESTION: What actual trajectory did the Jamaa movement take, and how was it received by Luba people themselves?
