King John signed the Magna Carta yet the same year he also quit claimed all of his holdings to the Pope to get back in good graces so he could get into heaven and avoid hell.
This is the fundamental unfinished business of western civilization and perhaps the world:
The Protestants think the Magna Carta gave them freedom.
The Catholics have title to it all on paper.
Never gone to court. Remains inderterminate today. That it remains so is perhaps of advantage to various parties who continue the obfuscation.
