Religious education has changed considerably over the 100 years of the Religious Education Association (REA); urgency has increased for human communities to honor diversity. The focus of this article is realities, visions, and promises of cultural diversity. The article includes an overview of REA's recent history, exemplifying its efforts and limitations in diversity. It then turns to five commentaries on a multicultural future, drawing on autobiographical analysis, religious and educational literature, and empirical study. Authors explicate and argue for: engaging in post-colonial analysis, de-centering assumptions, searching for a story to claim, taking time, and entering deep waters.
