Written in Latin for students at the Gregorian University in Rome, Bernard Lonergan's De Deo Trino (The Triune God) is a monumental two-part examination of trinitarian theology published initially in 1961 and again, in revised form, in 1964. The first part, the pars dogmatica, is here translated into English in an edition that includes the original Latin on facing pages. The work begins with the Prolegomena, which traces the dialectical development of trinitarian doctrine by Christian thinkers from the time of the New Testament to the Council of Nicea (AD 325). Following is a discussion of five theses outlining the evolution of the principal features of trinitarian doctrine from the New Testament through the patristic era.
Along with its companion volume on systematics, The Triune God: Doctrines represents the most comprehensive treatment of trinitarian theology in recent centuries. This English translation ensures that Lonergan's masterpiece will at last be available in its entirety to contemporary readers.
Fr. Bernard Joseph Frances Lonergan, SJ, CC (Ph.D., Theology, Gregorian University (Rome), 1939; B.A., University of London, 1930), was an ordained Roman Catholic priest of the Jesuit order. As an economist and philosopher-theologian in the Thomist tradition, he taught at Loyola College (Montreal) (now Concordia University), Regis College (now federated within the University of Toronto), the Pontifical Gregorian University, Harvard University, and Boston College. He was named by Pope Paul VI one of the original members of the International Theological Commission.
He is the author of Insight: A Study of Human Understanding (1957) and Method in Theology (1972), which established what he called the Generalized Empirical Method (GEM). The University of Toronto Press is in process of publishing his work in a projected 25-volume collection edited by staff at the Lonergan Research Institute at Regis College.
"Lonergan is considered by many intellectuals to be the finest philosophic thinker of the 20th century." —TIME Magazine
