Yet the real interest of the Nonjuring schism was political rather than religious; and its roots go out to vital events of the past. At the bottom it is the obverse side of the Divine Right of kings that they represent. That theory, which was the main weapon of the early secular state against the pretensions of Rome, must naturally have commanded the allegiance of members of a church which James I, its main exponent, had declared of vital import to his very existence. Its main opponents, moreover, were Catholics and Dissenters; so that men like Andrewes must have felt that when they answered Bellarmine they were in substance also defenders of their Church. After the great controversy of James I's reign resistance as a duty had come to be regarded as a main element in Jesuit and Nonconformist teaching; with the result that its antithesis became, as a consequence of the political situation, no less integral a part of Church of England doctrine. For it was upon the monarchy that the Church had come to depend for its existence; and if resistance to the king were made, as Knox and Bellarmine had in substance made it, the main weapon of the dissenting churches there was little hope that it would continue to exist once the monarchy was overthrown. And it is this, unquestionably, which explains why stout ecclesiastics like Barrow and Jackson can write in what seems so Erastian a temper. When they urge the sovereignty of the State, their thesis is in truth the sovereignty of the Church; and that means the triumph of men who looked with contemptuous hatred upon Nonconformists of every sect. The Church of England taught non-resistance as the condition of its own survival.
