A synodal church makes assumptions about our basic ecclesial experience which takes place when we assemble liturgically, especially when we act eucharistically. The basic assumption is that we are a genuine human community knowing and relating to one another as brothers and sisters in baptism. Only real communities can authentically image the church's nature. This is a ‘bottom – up’ activity. If we wish this, then we must rediscover our liturgy and celebrate it in a new way as flowing out from a community and helping it to discover its own nature. This, in turn, makes demands on our understanding of ministry and its structures. While many Catholics endorse synodality, their willingness to change the shape of the presbyterate is uncertain.
