Not angels!
it refers to marriage, angels do not marry, and cannot have sex, Matt 22:30
Sons of God are the faithful Jn 1:12
Hebrews 1:5
For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
not at any time are angels called sons of God!
I don't know to whom you are responding to, but I am not saying anything about angels. Adam was the son of God, and Jesus was the son of God. Jesus says "I am the first (Adam) and I am the last (Adam)" Adam and Jesus are the same. He is the son of God in the flesh.
No angels involved here!
