Can you explain why the Catholic Mass is out of a book?

[SanctusVeritas]

I have a Protestant cousin who kept asking me why the Mass is “out of a book”. I think I understand why, but I’m having trouble explaining the concept of liturgical worship and where it comes from. Can you help me on how to explain this?
