Catherine Kelle is a contemporary Christian theologian and Professor of Constructive Theology at Drew University's Graduate Division of Religion. As a constructive theologian, Keller's work is oriented around social and ecological justice, poststructuralist theory, and feminist readings of scripture and theology. Both her early and her late work brings relational thinking into theology, focusing on the relational nature of the concept of the divine, and the forms of ecological interdependence within the framework of relational theology. Her work in process theology draws on the relational ontology of Alfred North Whitehead, fielding it in a postmodern, deconstructive framework.
