According to the creed of the Parsees the good law also came to Aderbat Mahresfant by family descent (p. 62). These new races of priests, who knew the sayings, invocations, and prayers of Zarathrustra, would then be joined by those among the races of the old fire-priests who approved of the reform, and the priesthood thus formed would be further strengthened by those who, deeply impressed by the new doctrine, sought and found reception as pupils into a family of the priests, thus entering into their circle, and becoming members of their families. United by a new doctrine and settled tenets, the priests who represented the reform would become united together more firmly than the priestly families of the old time. The priesthood could very well claim precedence of the warriors; on their prayers and sayings, their knowledge of the custom of sacrifice, depended the favour of the gods, the power of averting evil spirits, the removal of pollution, salvation in this world and the next. Yet they could not obtain such a position as the Brahmans held on the Ganges after the reform of the ancient faith, and the victory of Brahman over Indra. For in Iran there was no order of Çudras, no vanquished remnant of an old population, which created a sharp line of division even among the orders of the Aryas; and moreover the Brahmans were the first-born of Brahman, a purer incarnation of the divine nature than any other order. The world had not emanated from Auramazda; there were in Iran no gradations of beings in which the divine essence existed in a more or less pure condition. All had to fight against evil deities and against evil; the priests were the leaders in this struggle--this leadership and nothing more could they claim. In their lives they studied especial purity of body and mind; and they were pre-eminently "the pure men." Only by their means, at any rate with their assistance, could sacrifice be offered; from their mouths alone could the correct invocations be uttered to the gods, and the evil ones be driven away. Men were compelled to submit to the rules of the life acceptable to the gods of light, of pure conversation, which were accurately known to the priests only; they had to take upon themselves the expiations which the priests prescribed, in order to wipe out offences and sins and their consequences--but they had not to reverence in them, as was the case beyond the Indus, a class of creatures raised by birth to a higher level. Hence the sharp separation of the priesthood from the rest of the orders, in the Brahmanic fashion, was at once placed out of the question. The priesthood of Iran perpetuated their knowledge and wisdom in their families; but they had not the right to bar all entrance into their families or their order on the score of higher birth, or to prohibit the marriage of priests with women of other orders, on the ground of their superior nature.
