One surprising aspect of the Synod on Synodality was the openness of the questions asked of the people of God and the wide range of their responses. The Synod functioned not only as a deliberative process, but as a process of aletheia, an "unveiling" of the reality of ecclesial difference and disagreement, especially with regard to issues of gender, sexuality, and sexual expression. The synod process unveiled the extent to which Catholics of good will lived out their faith and expressed their belief in different, sometimes conflicting ways. This paper highlights particular challenges for the implementation of synodality in the wider church. First, it will look at the challenge to simplistic images of ecclesial unity of belief and practice that the synodal unveiling of ecclesial disagreement has brought to the collective ecclesiological consciousness of Catholics. Second, it will look at the particular challenge of a synodal process that listened to Catholics whose views and experiences differ from official teaching and practice (e.g., LGBTQ+ Catholics, those seeking greater leadership roles and/or ordination for women, Catholics in polygamous marriages), without substantively changing ecclesial positions in these areas. How does a synodal church begin to address the extent and depth of the disagreement that the very process of synodality unveils?
