He then became Manager and Chaplain at Kigeme High School (1983–1986) before attending Makumira University College (Arusha, Tanzania), graduating with a Bachelor of Divinity (BD) in 1989.
In May 1994, Ruhumuliza wrote to the secretary general of the All Africa Conference of Churches, Jose Chipenda, defending the government and blaming the mass killings on its opponents, the Rwandan Patriotic Front.
Ruhumuliza wrote that the Rwandan prime minister, Jean Kambanda, and members of his cabinet were touring Rwanda to appeal for unity and peace when in fact they were whipping up the killing.
[3] In June 1994, Ruhumuliza and the Anglican archbishop of Rwanda, Augustin Nshamihigo, held a press conference in Kenya in which they claimed the RPF was leading the massacres and that the government was attempting to stop the killing.
[4] Nshamihigo's successor as archbishop, Emmanuel Kolini, accused Ruhumuliza of collaborating with the Hutu extremist government as an "errand boy" and described the Anglican church in Rwanda during the genocide as "corrupt".
[2] In 1996, he apologised for not speaking out strongly enough against the massacres and asked for forgiveness "because I did not continue to energetically condemn either the tragedy which was in progress or the state communiqués which were broadcast on the radios during this time".
