While England was not founded on the sovereignity of the individual based on God-granted rights that changed. England, like all monarchies was founded on the divine right of Kings to rule. King John abused that power and to stop a civil war against his authority he signed the Magna Carta which recognized certain inalienable God-granted rights.
Magna Carta is about king granted rights, not God-granted rights.
'Magna Carta's philosophy of king-granted rights stands, therefore, for the antithesis of the traditional American philosophy of Man-over-Government, based upon the uniquely American concept of God-given, unalienable rights safeguarded by a system of constitutionally limited government created by the sovereign people, under a written Constitution adopted by them, primarily to make and keep these rights secure.'
Magna Carta's King-granted Rights
It was actually about forcing the King to recognize that everyone had God given rights. Not just him, and the nobles had the power to defend those rights. At the time the Magna Carta was written, the King was God on earth. God said whatever the King said He said. By forcing the King to accept inalienable rights granted by God, as God's own representative, those rights came through the King. They had to. There was no other way except to declare the King had no right to rule at all and no one was willing to do that.
Americans had no King and no divine right of Kings to rule. And no intermediary was necessary for our rights to come directly from God.
It's a distinction without a difference, but a distinction nonetheless.
What we have now is a recognition that the Constitution, which secures and protects those rights only exists as long as there are people to defend the rights it secures. When people stop believing they have rights that come from God, the Constitution become unnecessary and inapplicable.
Our founders knew at the time the Constitution was written that it would not last forever. It would be set aside in favor of despotism.
Benjamin Franklin's speech.
Speech of Benjamin Franklin - The U.S. Constitution Online - USConstitution.net
In these sentiments, Sir, I agree to this Constitution with all its faults, if they are such; because I think a general Government necessary for us, and there is no form of Government but what may be a blessing to the people if well administered, and believe farther that this is likely to be well administered for a course of years, and can only end in Despotism, as other forms have done before it, when the people shall become so corrupted as to need despotic Government, being incapable of any other.
If we have not reached that very day now, we are awfully close.
