The church of Ave Maria in the Catholic Diocese of Tombura Yambio (CDTY), South Sudan celebrates a hundred years of faith in Rii-Yubu payam on the 10th of December 10, 2023. This celebration marked a hundred years since the Comboni Missionaries arrived in the village of Ngboko in 1923. The Comboni missionaries came from Mupoi to Ngboko because there was a widespread of sleeping sickness in the area of Rii-Yubu, as they were treating the people who were suffering from sleeping sickness, they were also evangelizing, and the people of Rii-yubu welcomed the faith and have kept it burning for a hundred years now.

The second event was the rededication of the church of Ave Maria church after the renovation. The rededication of the church of Ave Maria took place on the 8th of December 2023 by the Bishop of CDTY.
