This article critically examines the Catholic–Anglican theological dialogue, centering on John Henry Newman’s ‘Primacy of God’, Catholic synodality, and Anglican comprehensiveness. It illuminates the interconnectedness of these elements, revealing their potential to enhance ecumenical conversations. Newman’s concept of communal faith and divine primacy resonates across both traditions, advocating a transformative, experiential spiritual journey. This study juxtaposes Newman’s stance on ecclesiastical authority and doctrinal development with contemporary synodal movements in the Catholic Church, paralleled by Anglican practices like the Lambeth Conferences. This comparison underscores a mutual commitment to participatory governance and theological inclusivity. Ultimately, the study envisions a unified Christian theology, fostering dialogue enriched by diverse traditions and promoting a harmonious convergence within the Christian theological spectrum.
