By establishing Christianity as the state religion of Great Britain, the King greatly honored the religion. And by assuming the governor of the Church of England (the state religion), the King was confident to have made the religion as the reinforcement of the spiritual force of his country.
Thus, by losing the war (the American Revolution), the King not only brought pain to his country, but also brought humiliation to his state religion - Christianity. The loss of the war weakened both the political life and the religious life of Great Britain.
From this example, we can see how cool-minded and wise was Jefferson to offer the idea of the separation of state and religion:
Quote:I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between Church and State.
--- Thomas Jefferson's letter to the Danbury Baptist Association in 1802
