The three leading topics of discussion among the negotiators at Uxbridge were, the church, the militia, and the state of Ireland. Bound by their unhappy covenant, and watched by their Scots colleagues, the English commissioners on the parliament side demanded the complete establishment of a presbyterian polity, and the substitution of what was called the directory for the Anglican liturgy. Upon this head there was little prospect of a union. The king had deeply imbibed the tenets of Andrews and Laud, believing an episcopal government indispensably necessary to the valid administration of the sacraments, and the very existence of a christian church. The Scots, and a portion of the English clergy, were equally confident that their presbyterian form was established by the apostles as a divine model, from which it was unlawful to depart.[278] Though most of the laity in this kingdom entertained less narrow opinions, the parliamentary commissioners thought the king ought rather to concede such a point than themselves, especially as his former consent to the abolition of episcopacy in Scotland weakened a good deal the force of his plea of conscience; while the royalists, even could they have persuaded their master, thought episcopacy, though not absolutely of divine right (a notion which they left to the churchmen), yet so highly beneficial to religion, and so important to the monarchy, that nothing less than extreme necessity, or at least the prospect of a signal advantage, could justify its abandonment. They offered however what in an earlier stage of their dissensions would have satisfied almost every man, that limited scheme of episcopal hierarchy, above-mentioned as approved by Usher, rendering the bishop among his presbyters much like the king in parliament, not free to exercise his jurisdiction, nor to confer orders without their consent, and offered to leave all ceremonies to the minister's discretion. Such a compromise would probably have pleased the English nation, averse to nothing in their established church except its abuses; but the parliamentary negotiators would not so much as enter into discussion upon it.[279]
