This volume focuses attention on four key themes in Christian ethics: hermeneutics, spirituality, kingdom ethics, and homosexuality. These themes feature prominently in the work of the Dutch theologian and ethicist Ad de Bruijne. De Bruijne developed an ethics that combines a focus on Christ (with an emphasis on spirituality, and on the kingdom of God) with a focus on public theology having an open eye for cultural developments). In his method for doing ethics, he moves beyond the foundationalist tendencies of his own tradition, inspired by ethicists like Stanley Hauerwas and Oliver O'Donovan, as well as by Abraham Kuyper (an important voice in his own neo-Calvinist tradition). Recently, he demonstrated the strength of his approach in an impressive and courageous study about homosexuality. This book makes his work available to an international audience by demonstrating its significance and taking De Bruijne's work as a starting point for further ethical reflections in dialogue with him. Until his retirement in 2026, Ad de Bruijne was Professor of Christian Ethics and Spirituality at the Theological University Utrecht (the Netherlands).
