"Radicalism," particularly in the context of religion, evokes ambivalent if not conflicting reactions. On the one hand, for many, religion provides a sanctuary from the "Sturm und Drang" of dramatic change and discontinuity, as well as feelings of security rooted in the anticipation of continuity. On the other hand, our Abrahamic traditions all embrace narratives of dramatic change, both for the individual and for the world. Personal salvation, in different formulations in Judaism, Christianity and Islam, are important components of the religious narrative. Looking ahead to a radically transformed world in messianic or millennial formulations is likewise a significant part of all of our religious narratives. Reaching inward, finding comfort and security in one theological formulation or another is appropriately in tension with the obligation to reach out and change the world and to transform ourselves as well.
