<DIV>The Second Vatican Council envisaged a more prominent role of the synod of bishops in the Catholic church. However, the idea of the fathers of the council never came to full fruition. In this survey, Edet discusses why the reality does not meet the expectations of many of the fathers at Vatican II in terms of collegiality, communion and trinitarian theology. Edet emphasizes that this failure has implications for the church's life and mission. The concentration of decisive authority in the pope and his curia largely undermines the significance of the conciliar teaching on collegiality-dialogue and participation in the exercise of authority in the church. Edet offers an explanatory comparative investigation and evaluation of the Roman Catholic synod of bishops in relation to similar institutions in the Eastern Catholic and Anglican churches, as well as to the reflections on collegiality and synodality in some of the ecumenical dialogues.</DIV>
