How did these terms become common? What do they mean, exactly (I vaguely know)?
What words mean the same thing - like 'calvinist' and 'reformed'. Are they the same ideas? Because if yes, I think 'reformed' is a better name because it takes away the focus on John Calvin, which is good cause we shouldn't focus on him. And if they're different, then how? If they're different, then I need to wonder about another label in my life.
lots of labels, lots of terms, lots of things you could focus on that make you different.
