In their book Reformed Catholicity: The Promise of Retrieval for Theology and Biblical Interpretation (Baker Academic), Allen and Swain suggest Reformed Christians can commit not only to the ultimate authority of Scripture but also to receiving Scripture within the context of the apostolic church. This manifesto presents a case that to be Reformed means to go deeper into true catholicity rather than away from it. At the same time, it means holding fast to sola Scriptura.

Michael Allen is Associate Professor of Systematic and Historical Theology and Dean of Students and Scott Swain is Associate Professor of Systematic Theology and Academic Dean at Reformed Theological Seminary in Orlando, Florida.

Throughout history, Genesis 6 has puzzled Bible interpreters. Who are the sons of God? Are they human royalty? Angelic beings? Demons? And who are the daughters of men? Did the union of these two produce demigod offspring who would plague the land? Rita F. Cefalu joins us to bring clarity to this discussion. Ms. Cefalu has written an excellent article, "Royal Priestly Heirs to the Restoration Promise of Genesis 3:15: A Biblical Theological Perspective on the Sons of God in Genesis 6" published in the Westminster Theological Journal. Building upon Meredith Kline, but offering her own interpretation on the matter, Ms. Cefalu provides a thorough and compelling treatment of this difficult passage.

Ms. Cefalu is Adjunct Assistant Professor of Theology and Religious Studies at the University of San Diego. She is a graduate of Westminster Seminary California (MA Theological Studies), Wheaton Graduate School, and a PhD candidate at Queens University Belfast.

6:1 When man began to multiply on the face of the land and daughters were born to them, ² the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose. ³ Then the Lord said, “My Spirit shall not abide in man forever, for he is flesh: his days shall be 120 years.” ⁴ The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown. (Genesis 6:1–4, English Standard Version)

Lane Tipton and Camden Bucey speak about theophanies before turning  to pages 72–76 of Geerhardus Vos's Biblical Theology to speak about the Angel of Jehovah, or the Angel of the Lord.

Building upon Geerhardus Vos's foundational essay "The Eschatological Aspect of the Pauline Conception of the Spirit" Dr. Lane Tipton develops the role of the Spirit with regard to redemptive history, the law and soteriology. Vos remarks that the core of Paul’s eschatology lies in the sphere of the Spirit. The Spirit, given to the resurrected Christ, inaugurates the eschatological age of the world to come. This world to come is realized climactically in the resurrection of Christ as the firstfruits of the one great resurrection of harvest in the Spirit.
