A friend and former parishioner of mine (Gavin Ferriby) has written an answer to my question (and a response to Prof. Seitz):
I deeply respect Christopher Seitz, but I think that he has trimmed the historical record too much so that it would fit into his argument.
As I have read both the sources and relevant scholarship, the Church of England in the 1780s found itself in as nearly an awkward position as the fledgling organization being set up in places like Connecticut, Pennsylvania, and Virginia, at the very time when the character and polity of the United States itself was in play. It is as hazardous to justify or condemn any “mind of the house” of the House of Bishops now on the basis of decisions and negotiations in the 1780s as it is to condemn the “mind of the House” of either the chamber of U.S. Congress (regarding, say, the scope of Presidential power) on the basis of negotiations and compromises made at the constitutional convention and subsequent negotiations over the Bill of Rights.
Seitz just presses his evidence of negotiations for a “carefully redefined” polity too far: in the end, the Archbishop of Canterbury would NOT consecrate Seabury and so Seabury went to the Scots. In the 1780s the new-national Americans were trying to envisage a polity with Bishops which would differ from the English model of Bishops with temporal political responsibilities in the House of Lords –and this at a time when ecclesiastical disestablishment was by no means a done deal in the newly independent states. (Examples: the Congregational churches were obviously well established and financed in New England; the Dutch Reformed church continued to be publicly funded outside the five downstate counties of New York, and maybe within them; public financing of former Church of England parishes in other former-colonies-now-states was in play and although funds were not then currently provided, claims to funding were by no means lightly dismissed or lightly surrendered.)
In the 18th century I suspect it would have been difficult for any Archbishops of Canterbury or York to envision a proper Church of England outside the dominions of His Britannic Majesty because HRH the King was of course the Supreme Governor of the Church. James VI & I’s memorable phrase, “no bishop, no King” worked both ways. What Seabury and the American convention wanted was simply unprecedented and the legal establishment (or Establishment) in England regarded it dubiously. The spectre of “weak” constitutionally-bound Bishops would have raised for them uncomfortable memories of Civil War and various Scottish compromises under the early Stuarts, none of which endured. In the end the Archbishops in England were to say the least unenthusiastic. It is remarkable that John Henry Hobart (as skillfully delineated in Bruce Mullin’s excellent work) appealed very little to English precedent and law when he promulgated his early “high” vision of the Episcopal polity: he depended far more on the Bible and the early Fathers and a few of the “high” Caroline divines who of course could have no opinion about an American Church-of-England-like organization.
As a historian, I am deeply aware that a lot of water has flowed down the river since the founding moments of the 1780s. The Anglican Communion, whatever character is has or may have in the future, cannot be historically justified on the basis of 17th-18th century developments in polity either here or abroad. It has to have its own raison d’etre formulated in our times –expression of which will include, one hopes indeed, appeals to the example of Christian origins as well as the Protestant and Catholic reformations of the 16th and 17th centuries.
It is far more pertinent to the argument which Christopher Seitz joins that no Anglican bishops anywhere have expressly granted any primatial colloquy authority to over-rule any provincial primate even in matters of faith, morals, or order. I am sure that if, for example, the province of Australia (whatever it is called) proceeds with a robust version of lay presidency at the Holy Eucharist, other provinces may well express their vocal displeasure and discomfort. Will the Australians allow a primatial colloquy to provide alternative oversight by bishops for those Australians who might oppose such lay presidency? Has the Anglican Communion in fact shifted de facto to this primatial-conciliar vision, but not de jure? The “de jure” is a crucial move, one as yet hypothetical.
