After these matters this Jew of Celsus, instead of the Magi mentioned in the Gospel, says that “Chaldeans are spoken of by Jesus as having been induced to come to him at his birth, and to worship him while yet an infant as a God, and to have made this known to Herod the tetrarch; and that the latter sent and slew all the infants that had been born about the same time, thinking that in this way he would ensure his death among the others; and that he was led to do this through fear that, if Jesus lived to a sufficient age, he would obtain the throne.”
See now in this instance the blunder of one who cannot distinguish between Magi and Chaldeans, nor perceive that what they profess is different, and so has falsified the Gospel narrative. I know not, moreover, why he has passed by in silence the cause which led the Magi to come, and why he has not stated, according to the scriptural account, that it was a star seen by them in the east. Let us see now what answer we have to make to these statements. The star that was seen in the east we consider to have been a new star, unlike any of the other well-known planetary bodies, either those in the firmament above or those among the lower orbs, but partaking of the nature of those celestial bodies which appear at times, such as comets, or those meteors which resemble beams of wood, or beards, or wine jars, or any of those other names by which the Greeks are accustomed to describe their varying appearances.
And we establish our position in the following manner.
