What is the author's style in Babette's Feast by Karen Blixen?

Biblically well-read, Dinesen applies her knowledge of Scripture in "Babette's Feast" to underscore the strong religious overtones of Martine and Philippa's home they share with Babette. Throughout the story, subtle biblical allusions are introduced without reference, giving them the natural context of everyday thought that they have in the hearts of the sisters and the congregation. In describing the sisters' beauty in their youth, Dinesen explains that they caught the eyes of the men in the congregation. She writes that the older men "had been prizing the maidens far above rubies," an allusion to Proverbs 3:15 ("She is more precious than rubies; nothing you desire can compare to her") and Proverbs 31:10 ("A wife of noble character who can find? She is worth far more than rubies").
