Edward Schillebeeckx’s contribution to Catholic theology has not been without controversy, even compared with his contemporaries who are supposedly also ‘liberals’. Particular attention was pointed to his famous Jesus trilogy, and the use of hermeneutics he turned to at that stage in his career.2 Aside from the later controversies, Schillebeeckx’s career began with the works on sacramental theology, particularly with his doctoral thesis De Sacramentele Heilseconomie and his first major published work, Christ the Sacrament of the Encounter with God.3 That this remained a significant theme for Schillebeeckx is highlighted by the return to it he made towards the end of his life.4 Despite the obvious influence of a lived liturgical life upon his sacramental works, Schillebeeckx never wrote what we might straightforwardly call a liturgical theology, or at great length on the topic of liturgical reform. However, I believe, based on his sacramental thought, that there are many areas in which his insights can contribute to liturgical thought. I will begin to address some of them here, namely, History and the Incarnation, the nature of Christ as Sacrament, and derivative from that, the nature of the Church as Sacrament. This paper makes no greater claims than those of an initial exploration– a fuller treatment would need also to deal with other significant themes that emerge from Schillebeeckx’s theology of revelation and his fundamentally sacramental anthropology.
