Not the OP, but I might have some context.

I think of OOP as a message passing paradigm. It's concerned with how messages are passed from one part of the system to another. It is not particularly concerned with how those messages are implemented under the hood. In that sense it's a higher level paradigm because OOP is all about building abstractions ("objects") and defining how they communicate, rather than wiring code together directly. FP doesn't really have anything to say about how you design your abstractions, just how you implement them in code.
