I and II Thessalonians are letters written to the first, and then subsequent, generations of Christian communities in Thessalonica and the wider church. As our earliest Christian document, I Thessalonians is Paul's letter about how the Christian faith was interpreted in a new context twenty years after the beginning of the church. II Thessalonians, written by a teacher in the second generation of the Pauline school tradition, gives insights about how later generations interpreted the Pauline gospel, and is theologically instructive for our own efforts to do the same. In this new volume in the acclaimed New Testament Library series, M. Eugene Boring offers a scholarly interpretation of I and II Thessalonians while examining their historical context. Boring helps the reader learn to read these letters in context, particularly in relation to Paul's life as well as to the new converts who lived in Thessalonica. He addresses aspects such as structure, tone, style, language, and—for II Thessalonians—questions of authorship, while offering insightful theological perspectives.
