I can see now that my question wasn't very clear, as I struggled intitially when posting it as well, but you hit on part of it here. I know that Baptists are sola scriptura, and think I have a pretty good understanding about what that means for you. What I'm curious about (and what my original question was intended to ask) is what you have in parentheses above - that the Bible isn't the only way to know God, etc. (This isn't a leading question, I promise).
Catholics place importance on history, natural law, revelation within Creation, logic and reason among other things to explain and come to a knowledge of God. We of course have tradition as well, but that is not what I am asking here. And we recognize that history, natural law, and such won't "save" someone, but that they are important and useful elements of life on this earth.
In my experience with my friend who is a Baptist, she seems to deny many of these methods of knowing God. We've had conversations when I've said "well history says this" or "natural law tells us that," and she says "none of that matters because it's not in the Bible." So I'm wondering the extent to which all of this really does matter to a Baptist? Or is that another thing that's open to individual interpretation/personal use?
Another motive for my question, besides understanding my friend, is that it seems to me these are things that all people (even non-Christians) can recognize and understand; in fact, they're often a good place to start when talking with unbelievers. It would seem strange to me if a whole group of believing Christians would deny this ... so I'm just looking for some clarification.
