Actually it is christianity that must stand by itself, No people of the 'book'--Mandeans, Jews, Sabeans, Muslims, or any of the messengers, with or without books recognize a man God or believe in him including Jesus himself... so you go on deluding yourself with your Greek mythology is the way to go..
cheers
The reason the Jews as a whole don't accept Jesus as their Messiah is because God has largely placed a veil over their eyes. I say largely because God has still drew some Jewish people to Christ, ie Messianic Torah Judaism. But the Jews will come to realize that Christ is the Messiah en masse after the rapture of the church and during the seven year tribulation, when God's focus will shift back to the Jewish people and away from the Gentiles. Here's some scriptures to consider:
'I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.
God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel, saying,
Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life.
But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal.
Even so then at this present time also there is a remnant according to the election of grace.
And if by grace, then it is no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it,
and the rest were blinded.
(According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear

until this day.
And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them:
Let their eyes be darkened that they may not see, and bow down their back alway.
I say then, Have they stumbled that they should fall? God forbid:
but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?
...
For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
...
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits;
that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
For this is my covenant unto them, when I shall take away their sins.
Romans: 11: 1-12, 15, 25-27.
Also, consider this scripture which is in the Old Testament:
"I will pour out on the house of David and on the inhabitants of Jerusalem, the Spirit of grace and of supplication, so that they will look on Me whom they have pierced; and they will mourn for Him, as one mourns for an only son, and they will weep bitterly over Him like the bitter weeping over a firstborn.'
Zechariah: 12:10
