On the occasion of the awarding of the Pierre Coste Prize, December 12, 2016, from the Vincentian Studies Institute of DePaul University, Chicago, this address lays out issues involving the historiography of The Vincentians, the author's multi-volume general history of the Congregation of the Mission (1625-1980). Such issues are the interrelationships between different worlds or disciplines, a concern for the stories of individuals, geographical realities, Congregational legislation, the management of documentation, and spirituality.
