Why Psychology Needs Theology shows how Christian insights into human nature can be integrated with psychological theory and suggests ways that a basic understanding of faith might positively impact the therapeutic process. In the first part of the book, Nancey Murphy explores the core assumptions of psychology from the vantage point of her expertise in the philosophy of science. Psychology needs theology and ethics, she argues, to help it address the question of what constitutes a good life. Taking an Anabaptist, or Radical-Reformation, perspective that emphasizes Jesus' vulnerable love for his enemies and renunciation of power, Murphy challenges psychology to take seriously the goodness of self-renunciation. In the second part of the book, other scholars extend and challenge Murphy's model, discussing such topics as gender and culture. All those who work at the intersection of religion and psychology - teachers, pastors, specialists, and professional care providers - will find this exchange fruitful and valuable.
