2022 not only marks the 60th anniversary of the opening of the Second Vatican Council in October 1962 but it is also the 50th anniversary of the death of Belgian theologian, Gerard Philips, the architect of the Dogmatic Constitution on the Church, Lumen Gentium.
ACI invited Professor Mathijs Lamberigts, former director of the Vatican II Centre at the Catholic University of Leuven, Belgium, to be the presenter for our 13 September webinar entitled “Gerard Philips, Theologian, senator and promoter of the laity.”
Gerard Philips, theologian, senator and promoter of the laity
Born on 29 April 1899, Philips was an early and enthusiastic collaborator of Joseph Cardijn, founder of the Young Christian Workers (YCW) movement. During the 1930s, he played a key role as chaplain in the development of the Flemish Catholic students movement. Continuing his work with Cardijn, he promoted Specialised Catholic Action among generations of Belgian seminarians.
In 1952, he published his landmark book, De leek in de Kerk, translated into English as “The laity in the Church.” In 1957, he achieved further prominence with his keynote address to the Second World Congress on Lay Apostolate in Rome.
As a peritus at the Second Vatican Council, Philips was called on by Cardinal Léon-Joseph Suenens to write what became the first draft of the future Dogmatic Constution on the Church, Lumen Gentium. Later, he collaborated closely with French peritus, Pierre Haubtmann, in the drafting of the Pastoral Constitution on the Church in the World, Gaudium et Spes.
To these tasks, he brought his knowledge as a theologian but also the skills of diplomacy and negotiation that he had developed as a co-opted senator in the Belgian parliament
Originally from the Diocese of Liège, Gerard Philips taught at the University of Louvain (Leuven) from 1944 until his death on 14 July 1972.
