I found what I was looking for. Here it is in part (omitting the rest concerning resisting King George in particular.) It may be found at the lexrex site;http://www.lexrex.com/informed/otherdocuments/sermons/mayhew.htm
I also have to put it into 2 posts due to it's size.
"A Discourse Concerning Unlimited Submission and Non-Resistance to the Higher Powers" - Jonathan Mayhew
Harvard graduate and Congregationalist minister, Jonathan Mayhew (1720-1766) served the West Church in Boston from his ordination in 1747 until his death. The Discourse was first published in Boston in 1750.
. . . Let us now trace the apostle's reasoning in favor of submission to the higher powers, a little more particularly and exactly. For by this it will appear, on one hand, how good and conclusive it is, for submission to those rulers who exercise their power in a proper manner: And, on the other, how weak and trifling and unconnected it is, if it be supposed to be meant by the apostle to show the obligation and duty of obedience to tyrannical, oppressive rulers in common with others of a different character.
The apostle enters upon his subject thus--Let every soul be subject unto the higher powers; for there is no power but of God: the powers that be, are ordained of God. Here he urges the duty of obedience from this topic of argument, that civil rulers, as they are supposed to fulfill the pleasure of God, are the ordinance of God. But how is this an argument for obedience to such rulers as do not perform the pleasure of God, by doing good; but the pleasure of the devil, by doing evil; and such as are not, therefore, God's ministers, but the devil's! Whosoever, therefore, resisteth the power, resisteth the ordinance of God; and they that resist, shall receive to themselves damnation. Here the apostle argues, that those who resist a reasonable and just authority, which is agreeable to the will of God, do really resist the will of God himself; and will, therefore, be punished by him. But how does this prove, that those who resist a lawless, unreasonable power, which is contrary to the will of God, do therein resist the will and ordinance of God? Is resisting those who resist God's will, the same thing with resisting God? Or shall those who do so, receive to themselves damnation! For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? Do that which is good; and thou shalt have praise of the same. For he is the minister of God to thee for good. Here the apostle argues more explicitly than he had before done, for revering, and submitting to, magistracy, from this consideration, that such as really performed the duty of magistrates, would be enemies only to the evil actions of men, and would befriend and encourage the good: and so be a common blessing to society. But how is this an argument, that we must honor, and submit to, such magistrates as are not enemies to the evil actions of men; but to the good: and such as are not a common blessing, but a common curse, to society! But if thou do that which is evil, be afraid: For he is the minister of God, a revenger, to execute wrath upon him that doth evil. Here the apostle argues from the nature and end of magistracy, that such as did evil, (and such only) had reason to be afraid of the higher powers; it being part of their office to punish evildoers, no less than to defend and encourage such as do well. But if magistrates are unrighteous; if they are respecters of persons; if they are partial in their administration of justice; then those who do well have as much reason to be afraid, as those that do evil: there can be no safety for the good, nor any peculiar ground of terror to the unruly and injurious. So that, in this case, the main end of civil government will be frustrated. And what reason is there for submitting to that government, which does by no means answer the design of government? Wherefore ye must needs be subject not only for wrath, but also for conscience sake. Here the apostle argues the duty of a cheerful and conscientious submission to civil government, from the nature and end of magistracy as he had before laid it down, i.e. as the design of it was to punish evildoers, and to support and encourage such as do well; and as it must, if so exercised, be agreeable to the will of God. But how does what he here says, prove the duty of a cheerful and conscientious subjection to those who forfeit the character of rulers? to those who encourage the bad, and discourage the good? The argument here used no more proves it to be a sin to resist such rulers, than it does, to resist the devil, that he may flee from us. For one is as truly the minister of God as the other. For, for this cause pay you tribute also; for they are God's ministers, attending continually upon this very thing. Here the apostle argues the duty of paying taxes, from this consideration, that those who perform the duty of rulers, are continually attending upon the public welfare. But how does this argument conclude for paying taxes to such princes as are continually endeavoring to ruin the public? And especially when such payment would facilitate and promote this wicked design! Render therefore to all their dues; tribute, to whom tribute is due; custom, to whom custom; fear, to whom fear; honor, to whom honor. Here the apostle sums up what he had been saying concerning the duty of subjects to rulers. And his argument stands thus--"Since magistrates who execute their office well, are common benefactors to society; and may, in that respect, be properly stiled the ministers and ordinance of God; and since they are constantly employed in the service of the public; it becomes you to pay them tribute and custom; and to reverence, honor, and submit to, them in the execution of their respective offices." This is apparently good reasoning. But does this argument conclude for the duty of paying tribute, custom, reverence, honor and obedience, to such persons as (although they bear the title of rulers) use all their power to hurt and injure the public? such as are not God's ministers, but satan's? such as do not take care of, and attend upon, the public interest, but their own, to the ruin of the public? that is, in short, to such as have no natural and just claim at all to tribute, custom, reverence, honor and obedience? It is to be hoped that those who have any regard to the apostle's character as an inspired writer, or even as a man of common understanding, will not represent him as reasoning in such a loose incoherent manner; and drawing conclusions which have not the least relation to his premises. For what can be more absurd than an argument thus framed? "Rulers are, by their office, bound to consult the public welfare and the good of society: therefore you are bound to pay them tribute, to honor, and to submit to them, even when they destroy the public welfare, and are a common pest to society, by acting in direct contradiction to the nature and end of their office."
Thus, upon a careful review of the apostle's reasoning in this passage, it appears that his arguments to enforce submission, are of such a nature, as to conclude only in favor of submission to such rulers as he himself describes; i.e., such as rule for the good of society, which is the only end of their institution. Common tyrants, and public oppressors, are not intitled to obedience from their subjects, by virtue of any thing here laid down by the inspired apostle.
I now add, farther, that the apostle's argument is so far from proving it to be the duty of people to obey, and submit to, such rulers as act in contradiction to the public good, and so to the design of their office, that it proves the direct contrary. For, please to observe, that if the end of all civil government, be the good of society; if this be the thing that is aimed at in constituting civil rulers; and if the motive and argument for submission to government, be taken from the apparent usefulness of civil authority; it follows, that when no such good end can be answered by submission, there remains no argument or motive to enforce it; if instead of this good* end's being brought about by submission, a contrary end is brought about, and the ruin and misery of society effected by it, here is a plain and positive reason against submission in all such cases, should they ever happen. And therefore, in such cases, a regard to the public welfare, ought to make us withhold from our rulers, that obedience and subjection which it would, otherwise, be our duty to render to them. If it be our duty, for example, to obey our king, merely for this reason, that he rules for the public welfare, (which is the only argument the apostle makes use of) it follows, by a parity of reason, that when he turns tyrant, and makes his subjects his prey to devour and to destroy, instead of his charge to defend and cherish, we are bound to throw off our allegiance to him, and to resist; and that according to the tenor of the apostle's argument in this passage. Not to discontinue our allegiance, in this case, would be to join with the sovereign in promoting the slavery and misery of that society, the welfare of which, we ourselves, as well as our sovereign, are indispensably obliged to secure and promote, as far as in us lies. It is true the apostle puts no case of such a tyrannical prince; but by his grounding his argument for submission wholly upon the good of civil society; it is plain he implicitly authorizes, and even requires us to make resistance, whenever this shall be necessary to the public safety and happiness. Let me make use of this easy and familiar similitude to illustrate the point in hand--Suppose God requires a family of children, to obey their father and not to resist him; and enforces his command with this argument; that the superintendence and care and authority of a just and kind parent, will contribute to the happiness of the whole family; so that they ought to obey him for their own sakes more than for his: Suppose this parent at length runs distracted, and attempts, in his mad fit, to cut all his children's throats: Now, in this case, is not the reason before assigned, why these children should obey their parent while he continued of a sound mind, namely, their common good, a reason equally conclusive for disobeying and resisting him, since he is become delirious, and attempts their ruin? It makes no alteration in the argument, whether this parent, properly speaking, loses his reason; or does, while he retains his understanding, that which is as fatal in its consequences, as any thing he could do, were he really deprived of it. This similitude needs no formal application.
* This does not intend, their acting so in a few particular instances, which the best of rulers may do through mistake, &c. but their acting so habitually; and in a manner which plainly shows, that they aim at making themselves great, by the ruin of their subjects.
But it ought to be remembered, that if the duty of universal obedience and nonresistance to our king or prince, can be argued from this passage, the same unlimited submission under a republican, or any other form of government; and even to all the subordinate powers in any particular state, can be proved by it as well: which is more than those who alledge it for the mentioned purpose, would be willing should be inferred from it. So that this passage does not answer their purpose; but really overthrows and confutes it. This matter deserves to be more particularly considered.--The advocates for unlimited submission and passive obedience, do, if I mistake not, always speak with reference to kingly or monarchical government, as distinguished from all other forms; and, with reference to submitting to the will of the king, in distinction from all subordinate officers, acting beyond their commission, and the authority which they have received from the crown. It is not pretended that any person besides kings, have a divine right to do what they please, so that no one may resist them, without incurring the guilt of factiousness and rebellion. If any other supreme powers oppress the people, it is generally allowed, that the people may get redress, by resistance, if other methods prove ineffectual. And if any officers in a kingly government, go beyond the limits of that power which they have derived from the crown, (the supposed original source of all power and authority in the state) and attempt, illegally, to take away the properties and lives of their fellow subjects, they may be forcibly resisted, at least till application can be made to the crown. But as to the sovereign himself, he may not be resisted in any case; nor any of his officers, while they confine themselves within the bounds which he has prescribed to them. This is, I think, a true sketch of the principles of those who defend the doctrine of passive obedience and nonresistance. Now there is nothing in Scripture which supports this scheme of political principles. As to the passage under consideration, the apostle here speaks of civil rulers in general; of all persons in common, vested with authority for the good of society, without any particular reference to one form of government, more than to another; or to the supreme power in any particular state, more than to subordinate powers. The apostle does not concern himself with the different forms of government.** This he supposes left entirely to human prudence and discretion. Now the consequence of this is, that unlimited and passive obedience, is no more enjoined in this passage, under monarchical government; or to the supreme power in any state, than under all other species of government, which answer the end of government; or, to all the subordinate degrees of civil authority, from the highest to the lowest. Those, therefore, who would from this passage infer the guilt of resisting kings, in all cases whatever, though acting ever so contrary to the design of their office, must, if they will be consistent, go much farther, and infer from it the guilt of resistance under all other forms of government; and of resisting any petty officer in the state, tho' acting beyond his commission, in the most arbitrary, illegal manner possible. The argument holds equally strong in both cases. All civil rulers, as such, are the ordinance and ministers of God; and they are all, by the nature of their office, and in their respective spheres and stations, bound to consult the public welfare. With the same reason therefore, that any deny unlimited and passive obedience to be here enjoined under a republic or aristocracy, or any other established form of civil government; or to subordinate powers, acting in an illegal and oppressive manner; (with the same reason) others may deny, that such obedience is enjoined to a king or monarch, or any civil power whatever. For the apostle says nothing that is peculiar to kings; what he says, extends equally to all other persons whatever, vested with any civil office. They are all, in exactly the same sense, the ordinance of God; and the ministers of God; and obedience is equally enjoined to be paid to them all. For, as the apostle expresses it, there is NO POWER but of God: And we are required to render to ALL their DUES; and not MORE than their DUES. And what these dues are, and to whom they are to be rendered, the apostle sayeth not; but leaves to the reason and consciences of men to determine.
** The essence of government (I mean good government; and this is the only government which the apostle treats of in this passage) consists in the making and executing of good laws--laws attempered to the common felicity of the governed. And if this be, in fact, done, it is evidently, in it self, a thing of no consequence at all, what the particular form of government is;--whether the legislative and executive power be lodged in one and the same person, or in different persons;--whether in one person, whom we call an absolute monarch;--whether in a few, so as to constitute an aristocracy;--whether in many, so as to constitute a republic; or whether in three co-ordinate branches, in such manner as to make the government partake something of each of these forms; and to be, at the same time, essentially different from them all. If the end be attained, it is enough. But no form of government seems to be so unlikely to accomplish this end, as absolute monarchy--Nor is there any one that has so little pretence to a divine original, unless it be in this sense, that God first introduced it into, and thereby overturned, the common wealth of Israel, as a curse upon that people for their folly and wickedness, particularly in desiring such a government. (See I Sam. viii. chap.) Just so God, before, sent Quails amongst them, as a plague, and a curse, and not as a blessing. Numb. chap. xi.
