Can you give some examples of what you claim to be gnostic influence in the Septuagint?
Hello. Was going to avoid your question so as not to derail the Thread ... but it looks like my post with lots of good information was not actually read.
Basically "gnostic" = someone who thinks/says they "know-it-all" , or the "know-more-than-everyone-else" and/or they think that they were smarter than the words given to the Hebrew Prophets of old times.
They were primarily located ( but not solely ) around Egypt. They taught that Flesh is bad , and that spirit is good. They would often insert their ideas into texts which they were translating and or redacting.
There is much more detail on the subject. I will give you some references and titles to read and examine. Since you are in a big city in Australia , you should be able to access theses , if you do not own your own copy(s).
Enc. Britt. , 1994 ed. Micropaedia ,Ready Reference volume # 10 , page # 643. Septuagint. Good info , not very long, but good.
" " Volume # 5 , page # 315 . Not thorough , but provides basic information about Gnosticism.
"The Gnostics , The New Versions and The Diety of Christ" by Jay P. Green Sr. , Sovereign Grace Publishers , Indiana , U.S.A. ISBN 1-878442-71-6 This book has much information that any believer in Christ would want to read.
As I mentioned above ---> The gnostics thought flesh was bad , and only spirit was good. Thus , since Jesus the Messiah was born in Bethlehem to a Jewish woman with a human pedigree ,,, then by their thinking --- Jesus could not have really been "God". { Because ---> flesh is baaaaad , and only spirit is goooood . }
They spent much time and effort to undermine early Christianity. It is my contention ( and that of other folks who have studied this topic for years that Satan himself was behind the bad thinking and practices of the gnostics. The Devil is always trying to thwart Christianity and mess up Christian people.
Usually the Devil ( our adversary ) is subtle and quiet ,,, He does not walk around town in red pajamas with a red pitchfork in his hand ... Nope he has for centuries given ideas to philosophers and professors and writers and 'scholars' and government officials. He cannot attack the Church with a full frontal attack and smash down the gates ... but he can and has influenced many people & isms to cast doubts on scripture and to get people to question every portion of God's Book. From the gnostics to Marx & Lenin... always building up humans , and at the same time attacking majesty of The Lord God Almighty. By one word here and there over centuries the scriptures that tell of The Lord Jesus being Deity ( God in the flesh ) have often been changed or altered here and there.
Since your Bio and avatar show you to an Eastern Orthodox member ,,, then you know that Adam and Eve were made in the image & likeness of Our Creator --- God in Heaven. God designed those humans to have flesh & bones , and He is always correct ( and all God's children said : 'Amen!'

) . If God hated the flesh like the gnostics did ( and do ) then He would not have had His Only Begotten Son born of a woman in Bethlehem.
