In 1939 he formed a group called Mission des Noirs within Kimbangu"s movement, this group was later known as the Khakista because of the khaki uniform they wore. Mpadi used his first name to claim a connection to Kimbangu similar to that of Simon Peter to Jesus Christ. On 7 September 1939, in a declaration and written statement submitted to the local Belgian colonial administrator at Madimba (~ 90 km from Belgian Congo capital Leopoldville) his group (himself and hundreds of followers) sent a message to the colonial masters that their days in the territory they occupied were numbered, and that time for liberation and autochthons to cater for themselves had come.
He was then arrested and imprisoned.
In the mid-1940s Mpadi fled to the French Congo but was sent back to Belgian territories by the officials there. Mpadi argued that his movement could not be on a mission in their own land, but a church.
The movement came to later be known as "Eglise des Noirs Afrique" {which translates Church of Back (people) in Africa}, with headquarter at Ntendesi, later Songa-Ntela - a locality in the territory of Kasangulu, DRC. Mpadi"s sermons and religious message emphasized on the messianic and prophetic leadership of Simon Kimbangu as the liberator of all Black (people) in the world. He claimed the new approach not to be in contradiction with Kimbangu, but the true philosophy of Kimbangu initiated in year 1921.
In the 21st Century, his 1939 founded movement and church is still survived by few hundreds followers.
