In these pages Archbishop Piero Marini reveals the vision, courage, and faith of the pastors and scholars who struggled to implement the Second Vatican Council's teachings on the liturgy. While in some circles it is fashionable to propose "a reform of the liturgical reform," any such revision needs to take into account the history of the consilium-the organism established by the Holy See to carry out the initial liturgical changes. This story of the work of the consilium offers a fascinating glimpse into the struggles and tensions that accompanied the realization of the council's dream to promote the "full, conscious and active participation" of the faithful in Roman Catholic worship.
