"Examining the specific contributions of René Latourelle, Avery Dulles, Salvatore Marsilli, and Gustave Martelet against a background of pre-conciliar ressourcement theology, this volume provides a comprehensive account of why a Trinitarian and Christological construal of liturgy and sacraments as revelation is key to the vision that informed Vatican II, and it offers constructive theological and ecclesial possibilities for the future."--Back cover.
