Agreed. But that is not true of Protestantism, as a whole.............though for sure, some individuals do that.
I think this debate between Catholicism and Protestantism is off topic, but if there is ever a thread where it applies, I would enjoy discussing it with you.
I do see where you're coming from in terms of doctrine and authority, but where I have problems is your equating 'making up your own truth' with the absence of a church body interpreting Scripture on my behalf.
But to tell the truth, as Protestant churches getter farther and farther afield in throwing out all theology for the sake of popularity and ease, I am drawn more closely to the strength of Catholicism to buck the trends of pop culture and adhere to the truth of Scripture.
Actually I believe this difference is at the root of the question, "What is a creationist?". To me a creationist is someone who rejects the teaching authority (magisterium) of the sciences.
