And you are a teacher? Jude quoted from the book of Enoch and it is well known that the prophecies of Enoch was apart of the scriptures up to the third century. They shed much light on the Gen.6:1-4 event and the reason for the resulting flood. So, you are also incorrect in this respect.
In addition, you tried to use the following scripture to discount the angels as those being referred to as the sons of God:
"For to which of the angels did God ever say, “You are my Son, today I have begotten you”? Or again, “I will be to him a father, and he shall be to me a son”?
The scripture above is not saying that angels are not the sons of God, but are not the Begotten Son of God in the same capacity as Christ. The fact is that both angels and mankind are referred to as the sons of God in scripture.
Furthermore, you are claiming that the angels cannot be the sons of God because of the scripture above, but are assigning that designation as referring to the son's of Seth, as I recall. Well then, if we were to use your reasoning regarding the angels, I would also use your same reasoning, "to which of the offspring of men did God ever say, “You are my Son, today I have begotten you”? To use your answer that would be, never. Therefore using your own example, neither could any of those scriptures in Gen.6:1,4, Job 1:6, and 2:1 be referring to men.
The angels are the sons of God in a lesser or different capacity than Christ. For angels and mankind are created beings, where Jesus being God himself and was with God in the beginning, took on a body of flesh and being conceived through the power of the Holy Spirit. So the scripture is not saying that the angels are not sons of God, but that they are not what Jesus is, unique, begotten through the Holy Spirit.
This is also interesting in that, you admit that Jude quoted from Enoch, yet you disqualify the rest of Enoch's writing's in regards to the angels, as the sons of heaven, taking wives and the woman conceiving and bringing for giants. Since Enoch was inspired by the Holy Spirit to write what Jude quoted, then the rest of what Enoch wrote, including all the information regarding the angels who took wives, must also be inspired by the Holy Spirit. you can't pick and choose what you deem to be inspired and what isn't. Either all of the prophesies of Enoch are inspired or none of it.
"When man began to multiply on the face of the land and daughters were born to them,
the sons of God saw that the
daughters of man were attractive. And they took as their wives any they chose."
"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."
In the two scriptures above, there is a distinction being made between the "sons of God" and "man who bore daughters." That the sons of God came to the daughters of men, demonstrates a difference in type or genre, i.e. the sons of God who went to the daughters of men, are not men.
"Now there was a day when the sons of God came to present themselves before the Lord, and Satan[SUP]
