The account of the Nephilim in Genesis 6 has long been the subject of theological debate. While Scripture affirms the historical reality of the Nephilim (Genesis 6:1–4; Numbers 13:33; Deuteronomy 2–3; Joshua 12–13), the primary interpretive question concerns the identity of the “sons of God” (benê hāʾĕlōhîm) whose unions with the “daughters of men” preceded the Flood.

‍

The dominant modern interpretation identifies these “sons of God” as fallen angels. Our church rejects this interpretation as exegetically unsupported and theologically inconsistent. Instead, we affirm the Sethite interpretation, which understands the “sons of God” to be the godly descendants of Seth.

‍

Genesis 4–5 records two distinct human lineages: the line of Cain, characterized by rebellion and violence, and the line of Seth, associated with covenant faithfulness and worship. Scripture notes that during this time “men began to call upon the name of the LORD” (Genesis 4:26), marking the Sethite line as a people set apart for God. The designation “sons of God” is therefore understood to refer to these covenant descendants, while the “daughters of men” represent those outside this covenant community.

‍

The Nephilim themselves are described as “mighty men” or warriors of renown (Genesis 6:4), known for strength, reputation, and influence within a corrupt human society. Their existence does not require a hybrid or supernatural origin but reflects the rise of powerful human figures within a culture increasingly marked by violence and moral corruption.

The Nature of Angels

The angelic interpretation depends upon the assumption that spiritual beings possess the ability to cross the boundary between the spiritual and physical realms, assume biological form, and reproduce with human beings. Scripture provides no warrant for this assumption.

Angels are consistently described as spiritual beings, not biological or reproductive entities. Creation itself operates within divinely established boundaries, and Scripture never presents angels as possessing reproductive capacity.

Jesus Himself addresses the nature of angels directly, teaching that angels do not marry:
“For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven” (Matthew 22:30; cf. Mark 12:25; Luke 20:34–36).

Christ’s statement describes the essential nature of angels, not merely their current obedience. If angels do not marry, it follows that they are not sexual beings capable of procreation. The claim that fallen angels could reproduce with humans therefore contradicts the direct teaching of Christ.

Angelic Appearances in Scripture

The few biblical instances in which spiritual beings appear in physical form do not support the angelic interpretation. The only figure who repeatedly crosses the spiritual–physical boundary by divine prerogative is the Angel of the LORD, widely understood by many theologians as a pre-incarnate manifestation of Christ.

In these appearances, embodiment is temporary, purposeful, and initiated by God. Ordinary angels appear physically only in accompaniment to this figure and only in fulfillment of a divine mission. Scripture provides no example of angels independently assuming physical bodies, much less doing so for immoral or rebellious purposes.

Appeals to Jude and 2 Peter

Appeals to Jude 6 and 2 Peter 2:4 are also insufficient to support the angelic interpretation. While these passages speak of angels who sinned or abandoned their proper domain, neither passage explicitly connects these angels to Genesis 6, nor do they describe sexual relations with human women.

Reading angelic–human reproduction into these texts requires speculation that goes beyond what Scripture itself affirms.

The Sethite Interpretation

The Sethite interpretation fits naturally within the immediate literary and theological context of Genesis. Genesis 4–5 carefully traces two distinct human lines: the line of Cain, marked by violence and rebellion, and the line of Seth, characterized by covenant identity and worship.

Genesis 6 therefore describes the collapse of covenantal distinctions through intermarriage between the godly and the ungodly. This mixture resulted in widespread moral corruption, violence, and social decay, ultimately leading to the judgment of the Flood.
