This research addresses the reality of the Parish Pastoral Council as a privileged instrument for implementing the ecclesiology of the Second Vatican Council, especially in its image of communion and participation. With the conclusion of the Synod of Bishops on the theme of synodality and the search for ways so that the Church of the 21st century can live its mission of walking together, the Parish Pastoral Council, since its conciliar genesis and in its legal configuration in the Code of Canon Law, it was identified by the General Guidelines of the Church of Brazil as an effective instrument for the realization of the Church as communion and for involving the baptized, clergy, men and women religious, lay men and women in participation and in co-responsibility, making it clear that synodality was already happening in the Church of Brazil. The participation of baptized people in decision-making processes, accountability and evaluation practices occurs through institutional mediation, mainly in participation bodies. Pastoral conversion from a synodal perspective will be promising and noticeable when these organizations are assumed with all their effective efficiency and vitality, enabling the co-responsibility of all baptized men and women in the life and pastoral care of ecclesial communities. The Church will only achieve communion for all if there are participation structures that make such communion possible. In the Church of Brazil, the General Guidelines have guided this journey over the last 60 years.
