This is the inaugural issue of AGATHEOS – European Journal for Philosophy of Religion. This first issue embodies, in many ways, the broad aims and aspirations of the journal as a whole and features articles connected by the theme "Religious Diversity and the Future of Philosophy of Religion." We hope that the first papers of Agatheos will provoke further analysis of these and other important issues and advance and enrich a vibrant scholarly dialogue. We invite readers to engage deeply with these contributions and join us in exploring both traditional and novel topics in the ever-evolving landscape of the philosophy of religion.
