When Flipping into the first page of each chapter, the writer, Kingsolver, repeatedly uses versus from different books from the bible like the "book of genesis" or "book of the Revelation" which instantly gives the reader an idea of how the theme would be related to religious views.

"And God said unto them, Be fruitful, and multiply, ad replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth."Genesis 1:28

The significance and purpose of the Price family in Congo is the spreading of Christianity. I think the significance and usage of the Biblical allusion by the writer is to let us have a deeper understanding of the characters, and experience how a religious person views the world for instance, the protagonist's husband Nathan Price, a Strong pantheism which is really into his religious views of how all nature are a part of God, coming to Congo bringing all of their family members to spread their religious view which caused the protagonist Orleanna Price to regret marrying this insane pantheism. Overall, the way that the writer relates the bible to the character's thinking really helped me as a reader have an better insight of each character's intentions and thoughts.
