Hierapolis in the Heavens is a project which brings together several articles and essays that Kreitzer has written on the letter to the Ephesians and follows up a new suggestion which he first put forward in 1997 as to the setting and provenance of the epistle. Nothing quite like this has yet been published on Ephesians, particularly as it does offer some important new archaeological, textual and numismatic evidence for scholarly consideration. The book should also be of interest to social-historians of the first-century world as it argues that the letter we know as Ephesians was written to what was, in effect, a daughter-church of the church in Colossae; some intriguing questions about power-relations between churches such as this are opened up as a result.It was formerly known as 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 is also part of JSNTS. Journal for the Study of the Historical Jesus Supplement is also part of JSNTS.
