So ... we both agree that the Magna Carta was NOT influenced by the Protestant Reformation.
"Magna Carta, English Great Charter, charter of English liberties granted by King John on June 15, 1215, under threat of civil war and reissued, with alterations, in 1216, 1217, and 1225. By declaring the sovereign to be subject to the rule of law and documenting the liberties held by “free men,” the Magna Carta provided the foundation for individual rights in Anglo-American jurisprudence."

Magna Carta was not an instrument of democracy. It was an instrument of oligarchy and aristocracy, only drafted to protect the privileges of high born nobles -- no one else.
It was not until hundreds of years later that reformers in the shadow of the Protestant Reformation and the Glorious Revolution took the principles in Magna Carta and tried to extend them aspirationally to society more broadly.
