"Yes, the Virgin Mary appeared at Kibeho on 28 November 1981 and in the months that followed. There are more reasons to believe in the apparitions than to deny them. Only the three initial testimonies merit being considered authentic; they were given by Alphonsine Mumureke, Nathalie Mukamazimpaka, and by Marie Claire Mukangango. The Virgin appeared to them with the name "Nyina wa Jambo", that is "Mother of the Word", which is synonymous to "Umubyeyl W'iamna" that is, "Mother of God", as she herself explained."

"...Alphonsine, Nathalie and Marie Claire corresponded satisfactorily to all the criteria established by the Church in the matter of private apparitions and revelations."

--Bishop Augustin Misago of Gikongoro, Rwanda

“Repent, repent, repent!"

"Convert while there is still time." 

"The world hastens to its ruin, it will fall into the abyss”

"The world is rebellious against God, it commits too many sins, it has neither love nor peace."

"Faith and unbelief will come unseen."

Our Lady of Kibeho is the name given to reported Marian apparitions concerning several adolescents, in the 1980s in Kibeho, south-western Rwanda. They are the only Vatican-approved Marian apparitions in the continent of Africa.

The apparitions apparently communicated various messages to the schoolchildren, including an apocalyptic vision of Rwanda descending into violence and hatred, possibly foretelling the 1994 Rwandan genocide.

In 2001, the local bishop of the Catholic Church officially recognised the visions of three schoolchildren as authentic.
