At the same time as Catholic and evangelical Christians have increasingly come to agree on issues that divided them during the sixteenth-century reformations, they seem increasingly to disagree on issues of contemporary morality and ethics. Do such arguments doom the prospects for realistic full communion between Catholics and evangelicals? Or are such disagreements a new opportunity for Catholics and evangelicals to convert together to the triune God’s word and work on the communion of saints for the world? Or should our hope be different than simple pessimism or optimism? In this volume, eight authors address different aspects of these questions, hoping to move Christians a small step further toward the visible unity of the church.
