"The more interesting question, for me, was how this story of Magi locating the Messiah by astrological means, ever made it into the Holy Bible."
Who says they used astrology? "A star shall rise out of Jacob" isn't anything that needs interpreting by an astrologer. And who says the wise men were astrologers?
They might only have read the prophecy in Numbers, they might have been Jewish; all the text says is that they were "wise men". ("Magi" covers a lot of territory, and is in any case a Greek translation of a Hebrew word in Matthew.)
The author of the gospel of Matthew. They said "where is he...for we have seen his star...and have come to worship him." If that doesn't make it obvious, it further states that they used the star as a guide. No question they were following a star they could see, and that they attached to it an astrological signficance, and that they used their astrological learning to indicate who was born and where He'd be.
I won't quibble about whether they were astrologers or not, and I didn't call them astrologers, I said they used astrological means. The gospel is crystal clear on that.
