Okay, I was pleased as punch that you had the history correct, but the question of was it Biblically justified goes to the question of lex rex.
If the law is the authority, then the king could be in violation of the law. The local magistrate would be required to defend the citizens from a tyrannical ruler. It was those lesser magistrates that did declare independence, not the average Joe. George was NOT the law himself, and the colonists asserted the king was in violation of natural law ... even if one disagrees with that, it was their decision to make, not the colonist citizen. If one is to believe the veracity of the DoI, one would have to believe they engaged repeatedly in attempting to mitigate the problems without war. But the question of was it Biblical is a question of authority. The King was not submitting to the authority of law. The magistrates were.
Brian,
I appreciate the engagement. However, I'd like to take this up again on Monday if I'm able. The Lord's Day arrives sooner here!
