Missionaries used the theological term metanoia to force Africans to abandon their entire culture

Evidence

This means that some missionaries did not treat people they were evangelizing on equal terms. Like European philosophers, missionaries did not consider Africans as people who were sufficiently developed mentally to know God, to pray to Him, or to have a culture, morality or even a political system. That is why, under the theological term metanoia, they obliged converts to their respective denominations to literally abandon African culture in its entirety. — Frans Dokman, Beyond Bantu Philosophy_…, 139
