There are some mistakes in your mini-treatise.
“Under this arrangement there was no communication between man and God except by way of intercession of the church.”
That is patently false - or else no lay person would have prayed in the Middle Ages yet they did daily even hourly.
“Until the divine right of kings was shattered there was no hope of an expression of all men being created equal.”
Except the “divine right” of kings was an idea that showed up late in the Middle Ages and flourished well into the early modern era - including in Protestant countries. Apparently you’ve never heard of the Basilikon Doron of James VI of Scotland.
