This is a source-critical investigation of selected portions of the "Synoptic Gospels" and John's "Apocalypse". Paul Penley advances our understanding of the sources used behind the composition of John's "Apocalypse" by performing a source-critical investigation of selected portions of the "Synoptic Gospels" and John's "Apocalypse". Penley applies specific criteria for compositional influence (shared vocabulary, phrases, grammar, syntax, ideas, and contexts) to multiple portions of the "Apocalypse and of the Gospels of "Matthew" and "Luke" demonstrating that interpretive traditions controlling the appropriation of OT prophetic material in the Synoptic accounts of Jesus' message of Jerusalem's destruction also gave shape to parts of the message of judgment in John's "Apocalypse". It was formerly 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".
