Rev. Caleb E. Campbell graduated summa cum laude with a Masters of Arts in ministry from Phoenix Seminary in 2015 and is currently a doctoral student at Fuller Theological Seminary. He has served at Desert Springs Bible Church in Phoenix, Ariz., since 2006 and has served as lead pastor since 2015. He also serves on the board of United Pastors of Arizona and as the state-wide regional director of the Surge Network.
 
He is the founder and director of Disarming Leviathan Ministries which produces a podcast, explainer videos, and training material to equip people to missionally engage American Christian nationalists. 
 
His book, Disarming Leviathan (InterVarsity Press) equips Christians to minister to their Christian Nationalist neighbors. It introduces the basics of Christian nationalism, and explores the reasons so many people are attracted to it and provides a 'field guide' for responding to American Christian nationalist talking points along with questions and responses that “humbly subvert” their claims, and cultivate deeper, heart-level conversations.
