I am reading The Great Gatsby, and came to be curious as to what "the service of a vast, vulgar, and meretricious beauty" means in the following sentences:
His parents were shiftless and unsuccessful farm people—his imagination had never really accepted them as his parents at all. The truth was that Jay Gatsby of West Egg, Long Island, sprang from his Platonic conception of himself. He was a son of God—a phrase which, if it means anything, means just that—and he must be about His Father's business, the service of a vast, vulgar, and meretricious beauty. So he invented just the sort of Jay Gatsby that a seventeen-year-old boy would be likely to invent, and to this conception he was faithful to the end.
The young Gatsby found his humble family background unsatisfactory; that was why he began to imagine himself as somebody different, divine. Thus he started to reach for a higher goal in his life, such as earning a huge amount of money or winning Daisy's love.
But I could not understand especially what "the service of" meant. Does it mean that he provided such beauty? Or that he believed in such beauty?
And since "His Father's business" has some Biblical undertone in it, I would like to know whether the boldfaced phrase also has such a tone in it. I am not much knowledgeable when it comes to the Bible, so I would like to know whether there is some description that Jesus serviced some beauty, just like Gatsby, because I think that could give me some hint as to what was indeed "a vast, vulgar, and meretricious beauty."
I would very much appreciate your help.
