This chapter proposes that the author uses an ancient exegetical technique known as “prosopological exegesis.” This method was common in early Christianity, but is not often traced as far back as the NT. After establishing the author’s use, the chapter shows how this method developed out of Greco-Roman rhetorical training as well as literary criticism and also has resonances with Jewish reading strategies as well. Since this method was used by early Christian writers, such as Tertullian, to support a doctrine of the Trinity, this chapter also discusses the extent to which this is true of Hebrews. Finally, the chapter surveys previous literature on speech, or “the word of God,” in Hebrews.
