This book offers an examination of the Lukan themes of unity and disunity against ancient Greco-Roman and Jewish social and political discourses on concord and discord.This book examines the Lukan themes of unity and disunity against ancient Greco-Roman and Jewish social and political discourses on concord and discord to better understand the context in which Luke highlights the themes of unity and disunity.The themes of unity and disunity are particularly prominent in ancient discussions of the reigns of rulers, evaluations of laws/constitutions/forms of government, and descriptions of the contrasting effects of unity and disunity in the destruction and preservation of peoples and cities. These themes are grouped under the broad categories of kingship and law, and the preservation and destruction of cities. The book contends that, in the context of its literary setting, the theme of the unity of the church under one Lord in "Acts" contributes to Lukan Christological claims that Christ is the true king, and Lukan ecclesiological claims that the Christian community is the true people of God.This was formerly part of the "Journal for the Study of the New Testament Supplement", a book series that explores the many aspects of New Testament study, including historical perspectives, social-scientific and literary theory, and theological, cultural and contextual approaches. "The Early Christianity in Context" series, a part of JSNTS, examines the birth and development of early Christianity up to the end of the third century CE. The series places Christianity in its social, cultural, political and economic context. European Seminar on Christian Origins and "Journal for the Study of the Historical Jesus Supplement" are also part of JSNTS.
