The angels and Adam and Jesus are all called "sons" of God because they came directly from Him.
This is wrong.
This is wrong.
-Angels are referred to as "sons":
Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them.
Again there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them to present himself before the Lord.
Job 38:7 (this was before God created Adam and Eve)
When the morning stars sang together
And all the sons of God shouted for joy?
-Adam was referred to as God's "son"
Luke 3:23-38 (The genealogy of Jesus)
23 when He began His ministry, Jesus Himself was about thirty years of age, being, as was supposed, the son of Joseph, the son of Eli, the son of Matthat, the son of Levi, the son of Melchi, the son of Jannai, the son of Joseph......
...the son of Noah, the son of Lamech, the son of Methuselah, the son of Enoch, the son of Jared, the son of Mahalaleel, the son of Cainan, the son of Enosh, the son of Seth, the son of Adam, the son of God.
Jesus is referred to as God's son (except that Jesus is unique because he is the only begotten son)
“The beginning of the gospel of Jesus Christ, the Son of God.”
We, the church are called "sons" of God
(Romans 8:14) “For all who are being led by the Spirit of God, these are sons of God.”
(Romans 8:19) “For the anxious longing of the creation waits eagerly for the revealing of the sons of God.”
(Galatians 3:26) “For you are all sons of God through faith in Christ Jesus.”
So you see, the term "son" (of God) is not exclusive to Jesus. Again, am not saying that we or Adam or the angels are divine in any way (or anything of that sort). When in reference to God, "Son" means something that is "of God", i.e. coming directly from God. Mankind is not "the sons of God" because they did not come directly from God...rather, they are "the sons of men" (Gen 11:5, 1 Kings 8:39, Ps 14:2, Pr 8:4, Eccl 2:3, Mk 3:28). Adam came directly from God (Lk 3:38)...and mankind came from Adam (Acts 17:26). The reason I mentioned these other uses of the term "son" in my former comment was to give examples that the term does often refer to angels. In Genesis 6, the angels are referenced with the same title they are referenced elsewhere in the Bible. And for further strength I included Jude's remarks on the subject:
Jude 6-7 "Angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day, just as Sodom and Gomorrah and the cities around them, since they in the same way as these indulged in gross immorality and went after strange flesh."
...hence, the Nephilim
