Amy Peeler's dissertation is now published as a book:
Amy L. B. Peeler. You Are My Son: The Family of God in the Epistle to the Hebrews. The Library of New Testament Studies. Bloomsbury T & T Clark, 2014.
"The author of Hebrews calls God 'Father' only twice in his sermon.
This fact could account for scholarship's lack of attention to the
familial dynamics that run throughout the letter. Peeler argues,
however, that by having God articulate his identity as Father through
speaking Israel's Scriptures at the very beginning and near the end of
his sermon, the author sets a familial framework around his entire
exhortation. The author enriches the picture of God's family by
continually portraying Jesus as God's Son, the audience as God's many
sons, the blessings God bestows as inheritance, and the trials God
allows as pedagogy. The recurrence of the theme coalesces into a
powerful ontological reality for the audience: because God is the Father
of Jesus Christ, they too are the sons of God. But even more than the
model of sonship, Jesus' relationship with his Father ensures that the
children of God will endure the race of faith to a successful finish
because they are an integral part of comprehensive inheritance promised
by his Father and secured by his obedience. Because of the familial
relationship between God and Jesus, the audience of Hebrews - God's
children - can remain in the house of God forever."
Amy and I attended classes together at Princeton. We were working on our dissertations simultaneously and we had articles published in the same issue of Perspectives in Religious Studies in 2012. I am happy to endorse her book.
