that the revolt against ecclesiastical power would continue if every priest submitted.

"The Reformation," said Froude at the beginning of his first course, in November, 1892, "is the hinge on which all modern history turns." He traced in it the rise of England's greatness.
When he came back in his old age to Oxford, it was to sound the trumpet-note of private judgment and religious liberty, as if the Oxford Movement and the Anglo-Catholic revival had never been.
Froude could not be indifferent to the moral side of historical questions, or accept the doctrine that every one is right from his own point of view.

The Reformation did in his eyes determine that men were responsible to God alone, and not to priests or Churches, for their opinions and their deeds.

It also decided that the Church must be subordinate to the State, not the State to the Church.

This is called Erastianism, and is the bugbear of High Churchmen.
