As this source notes:
Picture yourself an American member of the colonial Church of England (COE) during or after the Revolutionary War. Your church was part of the royal government, the same government that people were fighting against. Perhaps you felt more allegiance to the Crown than your fellow colonists. After all, the Church of England in the United States (remember “Anglican” wasn’t a term in common use until the 19th century) attracted members of the merchant class, civil servants, royal governors, and others with strong ties to England.
If you left during the Revolution to go to Canada or return to England you weren’t alone. About 40% of Anglicans did. For those who stayed on after the war, their church was a shadow of its former self. Where the COE was the established (government-subsidized) church, such as the southern colonies and parts of New York, the church was quickly dis-established and lands sold off. Clergy, who took an oath of loyalty to the King, were caught in a dilemma: do you remain faithful to your ordination vows and support the King or side with the colonists who were part of the Revolution?It was a relatively orthodox Bishop named William White, who was a Whig (supported the rebellion) who led the effort to rewrite the faith into American Episcopalianism (you can read about it here). It obviously wasn't going to be a Tory like Samuel Seabury (the "farmer" whom Alexander Hamilton "refuted") playing the leading role in directing the new project. He was, you could view him as "too cold." On the other hand, Whig Bishop James Madison (the President's cousin and namesake) was probably too hot. William White was just right.
