Sengu Mbongu Rebecca (a name the Pende pronounced "Lebeka"), was a woman at the crossroads of traditional religion and Christianity. As a servant of God and others, she sowed the seeds of emancipation for Mennonite women in Kasaï Occidental. Sengu voluntarily stepped out of her culture, which did not send girls to school, but rather treated them as objects. She peacefully and politely embraced Christianity without outside pressure. After she was liberated from the grip of her ancestors, which was based on the inequality of the sexes, Sengu influenced other women to awaken spiritually and intellectually for the growth of the Church of Nyanga, the current headquarters of the Nyanga ecclesiastical district.
