I’m sorry for the harsh reply before, bibleguy. I’ve just seen a post from you in another thread, in which you at least profess that the Catholic Church is the one true Church, so your question was probably not maliciously intended or asked with ulterior motives. I suppose you have genuine curiosity and are interested in a fruitful discussion, despite your dangerously misguided comprehension of Catholic dogma. (Honestly, your question seemed like it must have come from an anti-Catholic who only knows as much about authoritative Church teaching as his pastor’s stock “Papist bashing” allows.) My bad.
As for the question…
You will always be the one who forms your conscience and its principles. You may insist on deriving all the important ones autonomously, strictly from your intuition and natural reason, or you may blindly adopt just the somewhat broader ones that the Church declares are binding, or, if you’re feeling particularly ambitious, you may attempt to harmonize the two into a comprehensive and particularly applicable set that you even understand. If hypothetically you ever had to choose between your own autonomy or the Church, then, well, I’d hope you choose the more humble route.
