Father Nemer lectures in Church history and missiology for aspiring missionary laymen and seminarians in indigenous regions and Europe. His Divine Word missionary order works as an international team and recruits from many countries. The Missionary Institute London, of which Father Nemer is president, accommodates and trains seminarians from seven religious orders. About 80 percent of the would-be missionaries come from the Third World, including 60 percent from Africa. Upon ordination, his students are sent by superiors away from home to teach and offer the sacraments in other cultures.
Obedience is a way of life for the missionary priest.
Father Nemer was asked by his order to study Church history at Catholic University in 1967. I've loved it. If I hadn't had such good teaching I don't know if I would have developed a love for history that I have done. Father Nemer cites Monsignor Robert F. Trisco's influence in his formation. He just drew that out of people.
