The Bangorian Controversy was a theological argument within the Church of England in the early 18th century, with strong political overtones. The origins of the controversy lay in the 1716 posthumous publication of George Hickes's Constitution of the Catholic Church, and the Nature and Consequences of Schism. In it, Hickes, on behalf of the minority non-juror faction who had broken away from the Church of England after the Glorious Revolution, as Bishop of Thetford excommunicated all but the non-juror churchmen. Benjamin Hoadly, the Bishop of Bangor, wrote a reply entitled, Preservative against the Principles and Practices of Non-Jurors; in it his own Erastian position was sincerely proposed as the only test of truth.
The controversy itself began very visibly and vocally when Hoadly delivered a sermon on 31 March 1717 to George I of Great Britain on The Nature of the Kingdom of Christ. His text was John 18:36, "My kingdom is not of this world," and from that Hoadly deduced, supposedly at the request of the king himself, that there is no Biblical justification for any church government of any sort. He identified the church with the kingdom of Heaven—it was therefore not of this world, and Christ had not delegated His authority to any representatives.
Two competing visions of government were in play. On the one hand, there was a vision of God appointing the king and the bishops to be leaders, selecting them from all others and imbuing them with special characters, either through grace or in creation. This view held that the king, as the head of the Established Church, was not merely a secular leader of a state, but also a religious primate. Power and regulation flowed downward from God to the people. This was the aristocratic model that was favoured by the Tory party and which had been used to propose the divine right of kings.
