What moral authority does the Catholic Church claim it is principled from?

You freepmailed me back that the better phrasing is

'What moral authority does the Catholic Church claim its principles from?'

A partial answer: in St John 17:18, St Luke 22:29-30.

I don't think the Catholic Church would agree.
