This document discusses the potential for "Big Theology" using big data approaches to analyze and understand theological data on a large scale. It begins by defining big data and explaining how digital theology analyzes theologically relevant data through digital platforms and tools. The document then proposes that big theology could represent, store, retrieve, analyze, predict, and visualize theological phenomena based on a global collection of digital religious expressions and narratives. Finally, it provides examples of potential applications of big theology, such as a mobile catechism, using data to promote peace, technologies for sacred spaces, and assisting church leadership. It concludes by discussing challenges and opportunities for international collaboration on big theology projects.
