In mission, it is not only that one practices love and justice, but also how one practices these virtues that makes the difference in the thriving of humankind. True love and justice require impassioned radical empowerment exemplified by the Incarnation; first, a full identification with poverty and abjectness, and then the relinquishment of power by the powerful and a taking up of power by the poor and the marginalized. This exchange of power needs to be based on mutuality. The present article defines and briefly elaborates on mutuality in its four forms. It then shows what mutuality illuminates and delimits and then indicates the relationship of mutuality to the traditional norms of love and justice. Finally, it indicates how consideration of mutuality can make a difference in mission.
