Question & Answer – Explain who are the “sons of God” and “daughters of men” in Genesis 6:2?

“That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.” 

Genesis 6:2

“The descendants of Seth were called the sons of God; the descendants of Cain, the sons of men. As the sons of God mingled with the sons of men, they became corrupt and, by intermarriage with them, lost, through the influence of their wives, their peculiar, holy character, and united with the sons of Cain in their idolatry. Many cast aside the fear of God and trampled upon His commandments. But there were a few that did righteousness, who feared and honored their Creator. Noah and his family were among the righteous few.” The Story of Redemption, 62. [Emphasis supplied.]

“The Scriptures briefly state the reason for the prevailing iniquity in Noah’s day. The sons of God married the daughters of men. Those who still cherished the knowledge of God united themselves with the ungodly and corrupt, and as a result became assimilated to them in character. The message of warning would have been received by a larger number, had it not been for their connection and association with those who despised and derided the word of God.” The Signs of the Times, February 16, 1882.

“For some time the two classes remained separate. The race of Cain, spreading from the place of their first settlement, dispersed over the plains and valleys where the children of Seth had dwelt; and the latter, in order to escape from their contaminating influence, withdrew to the mountains, and there made their home. … But in the lapse of time they ventured, little by little, to mingle with the inhabitants of the valleys. This association was productive of the worst results. ‘The sons of God saw the daughters of men that they were fair’ (Genesis 6:2). The children of Seth, attracted by the beauty of the daughters of Cain’s descendants, displeased the Lord by intermarrying with them. Many of the worshipers of God were beguiled into sin by the allurements that were now constantly before them, and they lost their peculiar, holy character. …”  Christ Triumphant, 38.

“The great crime in the marriages of the days of Noah was that the sons of God formed alliances with the daughters of men. Those who professed to acknowledge and revere God associated with those who were corrupt of heart; and without discrimination they married whom they would.” Messages to Young People, 456.
