That doesn't mean that history = truth.
It means that whatever history the Word of God contains is true.
The rest of history recorded elsewhere??? pfffft....
We are beginning to peal the onion that is the Reformation to reveal the underlying thought processes. Whereas my Catholic mind defines history as the accurate account of things past, verifiable and authoritative, your "Reformed" mind seems to approach it much like it does Scripture; history is a flexible and changeable portrayal in which accuracy does not seem to be as important an attribute as is malleability to fit any argument or position. It certainly explains many of the exchanges on these threads. It is no wonder we cannot agree on either history or Scripture.
"And he is not served by human hands, as if he needed anything. Rather, he himself gives everyone life and breath and everything else. From one man he made all the nations, that they should inhabit the whole earth; and he marked out their appointed times in history and the boundaries of their lands. God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us." - Acts 17:25-27
Peace be with you.
