Book excerpt: Thomas Blanton sheds light on the philosophy surrounding gift giving in Paul s letters and on modern theories of gift exchange through the lens of religion. The exchange of gifts is a fundamental part of society and a foundational element in Greco-Roman religions. Combining theories of gift exchange, both modern and Greco-Roman, Thomas Blanton reveals how religious discourse in the guise of spiritual gifts believed to come from Israel s god is instrumental in the formation of sociopolitical hierarchies and the assignment of honor and prestige. Blanton uses an interdisciplinary approach that incorporates religion, classics, sociology, and anthropology to investigate the economy of gift exchange shown in Paul s letters.
