In this book， Madison N。 Pierce analyzes the use of prosopological exegesis by the author of Hebrews in almost every major quotation of Scripture。 She shows that the author uses Scripture in a consistent way that develops his characterization of God - Father， Son， and Spirit - and that results in a triune portrait of God in Hebrews。 Offering a detailed reading of several passages， she also demonstrates how the author's portrayal of God is consistent with later theological developments。 Pierce's method replaces atomistic approaches and allows readers to see a clear pattern of usage across the entire epistle。 It offers researchers a tool for examining quotations of New Testament Scripture and will be of particular interest to those working in the field of trinitarian theology。
