The Inter-Religious Dialogue Program of the Boston Theological Institute involves a variety of activities among the member schools throughout the year. These include student programs, faculty colloquia, special lectures, and university-based research centers.

Part of the BTI's Inter-religious Dialogue program is called "Religious Neighbors," and is an experimental program designed to enrich the education of seminarians and other graduate students through a voluntary year-long series of visits to a variety of religious communities. Participants experience important aspects of a different religious tradition during each visit, and are given the opportunity for reflection and discussion.
