Catherine Keller
Board Member
Catherine Keller is the George T. Cobb Professor of Constructive Theology in the Theological School and Graduate Division of Religion of Drew University. She teaches courses in process, political, and ecological theology, and practices theology as a relation between ancient hints of ultimacy and current matters of urgency. Within and beyond Christian conversation, she has mobilized the transdisciplinary potential of feminist, philosophical, and pluralist intersections with religion. Her books include Facing Apocalypse: Climate, Democracy, and Other Last Chances, Political Theology of the Earth: Our Planetary Emergency and the Struggle for a New Public, Intercarnations: On the Possibility of Theology, and Cloud of the Impossible: Negative Theology and Planetary Entanglement. Her seminal work, On the Mystery: Discerning Divinity in Process, was published in second edition February 2026.

Rev. Dr. Leslie King is the Pastor of First Presbyterian Church of Waco. She received her BA from Kansas University (’91) and her Masters of Divinity from McCormick Presbyterian Theological Seminary in Chicago (‘94). In 2010 she completed her Doctor of Ministry at Saint Paul School of Theology in Kansas City Missouri with an emphasis in Spirituality and Organizational Change. She began her service to First Presbyterian Church of Waco in 2012. Process Theology has been a passion since 2007 when she began her Doctor of Ministry. Since September 2020, she is a yoga instructor (RYT 200) with Spirit Bear Yoga and (RYT 500) with My Vinaysa Practice. She’s a member of Yoga Alliance. She enjoys leading yoga flows for the youth and adults of the church. Her particular interest is in Yin and Restorative yoga as it relates to spiritual well-being. Piano competency is slowly emerging and music is a source of joy. She has been married to DJ King since November of 1996 and together they enjoy watching their three young adult children, Cody, Katie and Claire make their way in the world. With a menagerie of stray animals, the Kings are glad to call Waco home.
