Note 374 — Chapter XVIII · THE REFORMATION AND ITS EFFECTS UPON THE EMPIRE.
Reading edition
Henry VIII of England when he rebelled against the Pope called himself King of Ireland (his predecessors had used only the title 'Dominus Hiberniæ') without asking the Emperor's permission, in order to shew that he repudiated the temporal as well as the spiritual dominion of Rome.
So the Statute of Appeals is careful to deny and reject the authority of 'other foreign potentates,' meaning, no doubt, the Emperor as well as the Pope.
