Something quite extraordinary has happened in Catholic trinitarian theology in the last thirty years or so: the mystery of the Trinity is being approached by reflection on the paschal mystery of Jesus' death and resurrectionAstonishing though it may seem, the traditional Augustinian-Thomistic treatment of the trinity made no such direct reference to those Easter events, even though it was through them that Jesus' disciples came to proclaim that Jesus is Lord and that God is Father, Son, and Holy Spirit. The redemptive significance of Jesus' death and resurrection was clearly recognized, but not its revelatory significance. But here, in a radically new development, the death and resurrection of Jesus is perceived to have properly 'theological' meaning; it is not just redemptive but revelatory of God's being. A startling revitalized trinitarian theology emerges. 'So what does this development contribute to trinitarian theology?' And 'Why has this extraordinary development arisen at this stage in the tradition?' The Trinity and the Paschal Mystery answers these questions and examines and assesses this new developin relation to the classical tradition of trinitarian theology and offers a meta-methodological perspective from which to understand it.
