"Why did the Three Wise Men set off for Palestine? They were scholars of astrology and, seeing the comet, they attributed extraordinary significance to it because the doctrine of Zoroaster spoke of “a savior born of a virgin without the touch of a man,” the savior would restore the kingdom of good and evil, and his birth would be signaled by the appearance of a bright star. They therefore followed the path of the star and, knowing the Jews' expectation of a Messiah, set off, illuminated by divine grace."
