By way of critical appreciation, the author (an evangelical) investigates David Tracy's analysis of the Catholic imagination in relation to popular religiosity and inculturation in lowland Philippines. A survey of contemporary Evangelical and Roman Catholic views on folk religiosity sets the stage for the study as a whole. To explain and highlight the missiological significance of Tracy's approach, this study makes use of contemporary religio-philosophical (hermeneutical) and missiological perspectives. Such perspectives open up the missiological usefulness of Tracy's socio-theological analysis of the Catholic imagination especially for religionists and missiologists. They also point to the naturalistic limitations of Tracy's revisionist understanding of religion even as it encounters a non-Western religious outlook such as in the Philippines. A conversation with Tracy's approach becomes an instance of dialogue between Roman Catholics and Evangelicals not only on folk Catholicism, but also on revelation, inculturation and mission.
