First off, that is nonsense.
How can Jesus be a Hellenistic savior deity, when the book of Isaiah prophesizes about Jesus, which was some 400 years before the Hellenistic period even began.
Makes no sense.
"Isaiah was one of the most popular works among Jews in the
Second Temple period (c. 515 BCE – 70 CE)"
Isaiah was written in several parts, the last during the 2nd Temple Period. This period was when th eOT was revised and canonized.
"The Deutero-Isaian part of the book describes how God will make Jerusalem the centre of his worldwide rule through a royal saviour (a
messiah) who will destroy the oppressor (
Babylon); this messiah is the Persian king
Cyrus the Great, who is merely the agent who brings about Yahweh's kingship."
Book of Isaiah - Wikipedia
The Persian King. So when the Persians invaded Israel in 500 B.C. the Hebrews were greatly influenced by their myths. Messianic world saviors were one of the myths.
"Historically, the unique features of Zoroastrianism, such as its
monotheism,
[5] messianism, belief in
free will and
judgement after death, conception of
heaven,
hell,
angels, and
demons, among other concepts, may have influenced other religious and philosophical systems, including the
Abrahamic religions "
Now to the leading scholar on the Persians, Mary Boyce. Look her up. From her work:
"
Belief in a world Saviour
An important theological development during the dark ages of 'the faith concerned the growth of beliefs about the Saoshyant or coming Saviour. Passages in the Gathas suggest that Zoroaster was filled with a sense that the end of the world was imminent, and that Ahura Mazda had entrusted him with revealed truth in order to rouse mankind for their vital part in the final struggle. Yet he must have realized that he would not himself live to see Frasho-kereti; and he seems to have taught that after him there would come 'the man who is better than a good man' (Y 43.3), the Saoshyant. The literal meaning of Saoshyant is 'one who will bring benefit' ; and it is he who will lead humanity in the last battle against evil.c and so there is no betrayal, in this development of belief in the Saoshyant, of Zoroaster's own teachings about the part which mankind has to play in the great cosmic struggle. The Saoshyant is thought of as being accompanied, like kings and heroes, by Khvarenah, and it is in Yasht r 9 that the extant Avesta has most to tell of him. Khvarenah, it is said there (vv. 89, 92, 93), 'will accompany the victorious Saoshyant ... so that he may restore 9 existence .... When Astvat-ereta comes out from the Lake K;tsaoya, messenger of Mazda Ahura ... then he will drive the Drug out from the world of Asha.' This glorious moment was longed for by the faithful, and the hope of it was to be their strength and comfort in times of adversity.
Messianic world saviors who were virgin born, taken from the Persians.
Hellenism came later. The NT is completely Hellenistic, everything in it is from Hellenism. I can detail all of the Hellenistic concepts that entered Judaism (and all the religions in the area)
The Hellenistic World: The World of Alexander the Great
Hellenistic thought is evident in the narratives which make up the books of the Bible as the Hebrew Scriptures were revised and canonized during the Second Temple Period (c.515 BCE-70 CE), the latter part of which was during the
Hellenic Period of the region.
The gospels and epistles of the Christian New Testament were written in Greek and draw on
Greek philosophy and religion as, for example, in the first chapter of the Gospel of John in which the word becomes flesh, a Platonic concept.
Newsflash: Judaism predates Zoroastrianism.
The OT began it's writing in 600 B.C. The Israelites began as a people around 1200.
Mary Boyce:
"The language of the Gathas is archaic, and close to that of the Rigveda (whose composition has been assigned to about 1 700 B. c. onwards); and the picture of the world to be gained from them is correspon,dingly ancient, that of a Stone Age society. Some allowance may have to be made for literary conservatism; and it is also possible that the 'Avestan' people (as Zoroaster's own tribe is called for want of a better name) were poor or isolated, and so not rapidly influenced by the developments of the Bronze Age. It is only possible therefore to hazard a reasoned conjecture that Zoroaster lived some time between 1 700 and 1 500 B.C"
The Persian myths were fully formed by the 2nd Temple Period. It impacted ideas on Satan, Revelation, messianic figures, God vs Satan and more.
As usual, the skeptic focuses on the similarities, with very little (of any) focus on the differences.
At the end there are not many differences. The OT is Mesopotamian and the NT is Greek/Persian.
The early 2nd century apologists like Martyr even told the people Jesus was so much like all the Greek savior demigods because Satan made it look that way to fool Christians.
Saint Justin Martyr (110-165)
Chapter 69
I continued, “that I am established in the knowledge of and faith in the Scriptures by those counterfeits which he who is called the devil is said to have performed among the Greeks; ....
For when they tell that Bacchus, son of Jupiter, was begotten by [Jupiter’s] intercourse with Semele, and that he was the discoverer of the vine; and when they relate, that being torn in pieces, and having died, he rose again, and ascended to heaven; and when they introduce wine into his mysteries, do I not perceive that [the devil] has imitated the prophecy announced by the patriarch Jacob, and recorded by Moses? And when they tell that Hercules was strong, and travelled over all the world, and was begotten by Jove of Alcmene, and ascended to heaven when he died, do I not perceive that the Scripture which speaks of Christ, ‘strong as a giant to run his race,’ has been in like manner imitated? And when he [the devil] brings forward Æsculapius as the raiser of the dead and healer of all diseases, may I not say that in this matter likewise he has imitated the prophecies about Christ? But since I have not quoted to you such Scripture as tells that Christ will do these things, I must necessarily remind you of one such: from which you can understand, how that to those destitute of a knowledge of God, I mean the Gentiles, who, ‘having eyes, saw not, and having a heart, understood not,’ worshipping the images of wood, [how even to them] Scripture prophesied that they would renounce these [vanities], and hope in this Christ.
