On this point the theory of Rawlinson is very important. He argues, with various proofs, that the Dualistic doctrine was a heresy which broke out very early among the primitive Aryans, who then were the single ancestry of the subsequent Iranians and Indians. This heresy was forcibly suppressed. Its adherents, driven out of India, went to Persia, and, after severe conflicts and final admixture with the Magians, there established their faith.34 The sole passage in the Old Testament teaching the resurrection is in the so called Book of Daniel, a book full of Chaldean and Persian allusions, written less than two centuries before Christ, long after we know it was a received Zoroastrian tenet, and long after the Hebrews had been exposed to the whole tide and atmosphere of the triumphant Persian power. The unchangeable tenacity of the Medes and Persians is a proverb. How often the Hebrew people lapsed into idolatry, accepting Pagan gods, doctrines, and ritual, is notorious. And, in particular, how completely subject they were to Persian influence appears clearly in large parts of the Biblical history, especially in the Books of Esther and Ezekiel. The origin of the term Beelzebub, too, in the New Testament, is plain. To say that the Persians derived the doctrine of the resurrection from the Jews seems to us as arbitrary as it would be to affirm that they also borrowed from them the custom, mentioned by Ezekiel, of weeping for Tammuz in the gates of the temple. In view of the whole case as it stands, until further researches either strengthen it or put a different aspect upon it, we feel forced to think that the doctrine of a general resurrection was a component element in the ancient Avestan religion. A further question of considerable interest arises as to the nature of this resurrection, whether it was conceived as physical or as spiritual. We have no data to furnish a determinate answer. Plutarch quotes from Theopompus the opinion of the Magi, that when, at the subdual of Ahriman, men are restored to life, "they will need no nourishment and cast no shadow." It would appear, then, that they must be spirits. The inference is not reliable; for the idea may be that all causes of decay will be removed, so that no food will be necessary to supply the wasting processes which no longer exist; and that the entire creation will be so full of light that a shadow will be impossible. It might be thought that the familiar Persian conception of angels, both good and evil, fervers and devs, and the reception of departed souls into their company, with Ormuzd in Garotman, or with Ahriman in Dutsakh, would exclude the belief in a future bodily resurrection. But Christians and Mohammedans at this day believe in immaterial angels and devils, and in the immediate entrance of disembodied souls upon reward or 33 Die Lehre Zoroasters nach den alten Liedern des Zendavesta.
