Fr. Jef was born in Belgium on 4 March 1937. He took his first vows as an Oblate on 8 September 1958 and was ordained a priest on 26 December 1963. He arrived in South Africa on 31 January 1965.
For 55 years, he has been a dedicated and faithful missionary in the Tswana-speaking area, now the North West Province of South Africa. There is much evidence of how close he was to the people and the success of his pioneering pastoral ministry over the years. He enjoyed starting new Christian communities, which became parishes or sub-stations of parishes in what has now become the Diocese of Klerksdorp.
Archbishop Victor Phalana, Bishop of Klerksdorp believes the robbers were misinformed: “Everyone knows he had no money. He served a poor community. He used every penny he ever owned for his people. He gave away everything he had”.
