Did Zoroastrianism predate the Christian religion? Did Satan copy so many similaritie

History
Zarathustra (in Greek, Zoroaster) was a Persian prophet who at the age of 30 believed he had seen visions of God, whom he called Ahura Mazda, the creator of all that is good and who alone is worthy of worship. This was a departure from previous Indo-Persian polytheism, and Zarathustra has been termed the first non-biblical monotheist. There is disagreement among scholars as to exactly when and where Zarathustra lived, but most agree that he lived in eastern Iran around the sixth century BC.

Zoroastrianism became the official religion of the Persian Empire, but it virtually disappeared in Persia after the Muslim invasion of 637 AD. Only about 10,000 survive in remote villages in Iran, but over the centuries many sought religious freedom in India.

Texts
The Zoroastrian sacred text is the Avesta ("Book of the Law"), a fragmentary collection of sacred writings. Compiled over many centuries, the Avesta was not completed until Persia's Sassanid dynasty (226-641 AD). It consists of: liturgical works with hymns ascribed to Zarathustra (the Gathas); invocations and rituals to be used at festivals; hymns of praise; and spells against demons and prescriptions for purification.

Beliefs
The Zoroastrian concept of God incorporates both monotheism and dualism. In his visions, Zarathustra was taken up to heaven, where Ahura Mazda revealed that he had an opponent, Aura Mainyu, the spirit and promoter of evil. Ahura Mazda charged Zarathustra with the task of inviting all human beings to choose between him (good) and Aura Mainyu (evil).

Though Zoroastrianism was never as aggressively monotheistic as Judaism or Islam, it does represent an original attempt at unifying under the worship of one supreme god a polytheistic religion comparable to those of the ancient Greeks, Latins, Indians, and other early peoples.

Its other salient feature, namely dualism, was never understood in an absolute, rigorous fashion. Good and Evil fight an unequal battle in which the former is assured of triumph. God's omnipotence is thus only temporarily limited.

Zoroaster taught that man must enlist in this cosmic struggle because of his capacity of free choice. Thus Zoroastrianism is a highly ethical religion in which the choice of good over evil has almost cosmic importance. Zarathustra taught that humans are free to choose between right and wrong, truth and lie, and light and dark, and that their choices would affect their eternity destiny.

The Zoroastrian afterlife is determined by the balance of the good and evil deeds, words, and thoughts of the whole life. For those whose good deeds out weight the bad, heaven awaits. Those who did more evil than good go to hell (which has several levels corresponding to degrees of wickedness). There is an intermediate stage for those whose deeds weight out equally.

This general principle is not absolute, however, but allows for human weakness. All faults do not have to be registered or weighed forever on the scales. There are two means of effacing them: confession and the transfer of supererogatory merits (similar to the Roman Catholic "Treasury of Merits"). The latter is the basis for Zoroastrian prayers and ceremonies for the departed.

Zoroaster invoked saviors who, like the dawns of new days, would come to the world. He hoped himself to be one of them. After his death, the belief in coming saviors developed. He also incorporated belief in angels and demons.

Zoroaster's ideas of ethical monotheism, heaven, hell, Angelico, the resurrection of the body, and the messiah figure were influential on Judaism, Christianity, and Islam, though to what extent is not known for certain.

Thanxs ME for letting me know that Avesta was added as phony...My instinct told me that as well.

There are several religions that predate Christianity which Christianity borrows from. There's not much about it that's unique.

Yes, so did Hinduism, Buddhism, and several religions. The Magi in the Gospels were Zoroastrian priests.

Is there a question here?

i believe that the Jews got there stuff from the Zoroastrians not the Romans and Greeks. except maybe the name Lucifer from the Romans.

Zoroastrianism predated even Judaism, so obviously it will predate Christianity.

Gathas is the only real Zoroastrian book. It is what Zoroaster wrote. Avesta is phony crap added to Zoroastrianism

Yes, Zoroastrianism substantially predates Christianity, as well as Judaism. Satan didn't copy from the religion, Jewish priests did, plain and simple. Do some historical and religious study yourself. Satan is the Bogey man in the closet designed to scare people into churches so priests don't have to get a day job and can molest children with impunity.

It sure would be ironic if all of these deities we keep killing were all the same guy, just with a steep learning curve.

Yes to your question, Christianity borrowed components from several bordering lands including Egypt.

You lost me after "did Satan ..."

That's like asking will Elmer Fudd ever kill Bugs Bunny.

It's also speculated that Judaism was influenced by Atenism, a monotheistic (but short-lived) Egyptian Religion.

Religions always borrow from one another, it's no big surprise.
