See in my book (and the Merriam-Webster dictionary) rebellion means both opposition AND defiance. One can question, in the sense of going into the whys and wherefores behind particular beliefs, and in the end own one’s beliefs as a result of this questioning, without being either in opposition or defiance to anyone.
For an example in a non-religious context, my maths teacher might teach me Pythagoras’ theorem. My adolescent mind will say ‘but why? why does the square of one side of a right-angled triangle etc etc etc …’.
That’s the questioning and ‘owning my knowledge’ bit. Assume, being a good teacher, she then (most of my maths teachers seem to have been female for some reason) goes into the whys, wherefores and proofs of the theorem, until they logically click into place for me and I accept them.
Voila, we have an instance of my questioning and then owning my beliefs in a completely mature way (I hope you won’t say that someone who examines what her maths teacher teaches and then accepts it somehow isn’t thinking for herself or is only guilty of shallow thinking).
Note that it involves neither opposition (since in my questioning of the Theorem I never claimed to NOT believe it, simply to not understand it, which is all that a great percentage of questioning amounts to) nor defiance of any kind.
I’m sure there are people who go through their entire lives working out most or all of their beliefs by such processes - and no, they don’t all run away from home, nor defy their parents or other authority or teaching figures in other ways, nor claim beliefs that are contrary to those of the parents/others. Yet they still DO question and deeply think about, and still DO ‘own’ their beliefs.
