According to traditional scholarship, the author of the Epistle to the Hebrews, following in the footsteps of Paul, argued that Jewish Law, the cornerstone of the beliefs and traditions of the descendants of the founding fathers, had played a legitimate role in the past but was superseded by a new covenant that applies to Gentiles (cf. Rom. 7:1–6; Gal. 3:23–25; Heb. 8, 10). However, a growing number of scholars point that the terms Gentile, Christian and Christianity are not present in the text and posit that Hebrews was written for a Jewish audience, and is best seen as a debate between Jewish followers of Jesus and mainstream Judaism. In tone, and detail, Hebrews goes beyond Paul and attempts a more complex, nuanced, and openly adversarial definition of the relationship. The epistle opens with an exaltation of Jesus as "the radiance of God's glory, the express image of his being, and upholding all things by his powerful word". The epistle presents Jesus with the titles "pioneer" or "forerunner", "Son" and "Son of God", "priest" and "high priest". The epistle casts Jesus as both exalted Son and high priest, a unique dual Christology.
