Book excerpt: This book takes a distinctive approach to the same-sex-union debate by framing the issue as a matter of marriage. Darrin Snyder Belousek demonstrates that the interpretation of Scripture affects whether the church should revise its doctrine of marriage for the sake of sanctioning same-sex union. Engaging charitably yet critically with opposing viewpoints, he delves deeply into what marriage is, what it is for, and what it means as presented in the biblical narrative and the theological tradition, articulating a biblical-traditional theology of marriage for the contemporary church. Afterword by Wesley Hill.
