One distinctive way in which the Jesuit School of Theology engages in comparative theology, interreligious dialogue, and preparation for ministry in the 21st century is through an annual cycle of interreligious, theological, course-based immersions. These for-credit courses are electives, and yet are an important component of the JST curriculum. Scheduled in a three-year, repeating cycle, each immersion includes opportunities for comparative studies, dialogue, religious experience, theological reflection and social action. A fall course is followed by a three-week, in-country immersion during the January Intersession. Any JST degree-seeking student may apply for this course; the acceptance process is selective.
