Have you ever thought about the fact that the doctrine of Sola Scriptura is self contradictory in that it is itself not biblical?
As John Sanders said...
"The openness model is an attempt to provide a more biblically faithful, rationally coherent, and practically satisfying account of God and the divine-human relationship.." - John Sanders
"Is Open Theism Christian Theism?"
Only? Really?
Isn't your faith also sourced in God Himself, not only as the Author of scripture but in your own relationship with Him? Isn't your faith also confirmed by God's creation as well as natural law and the conviction of your own heart (i.e. mind)? Doesn't your every day experience confirm to you not only God's existence but His power and majesty?
Indeed, the bible tells us explicitly that all are without excuse, whether they have a copy of the scripture or not....
Romans 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, 19 because what may be known of God is manifest in them, for God has shown it to them. 20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, 21 because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. 22 Professing to be wise, they became fools, 23 and changed the glory of the incorruptible God into an image made like corruptible man—and birds and four-footed animals and creeping things.
Romans 2:14 For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
Totally true! 100%
Amen! The supremacy of God's word over any tradition of man or earthly authority is paramount and, I think, this is really what most regular people who use the term "Sola Scriptura" mean when they say it, and that's fine. I don't want to come off sounding like I have a big issue with it. It's just that I think it's easy to take such concepts too far and we should be careful about what we are implying, especially when we adopt the doctrinal terminology of those who are, as you say, "Platonists with Christian "window-dressing"". At bottom the doctrine of Sola Scriptura is based on the premise that God has exhaustive and absolute omniscience, which, in turn, is based on the premise of absolute divine immutability. Open Theism rejects both of those premises, by definition.
