Out of the religious wars between the Protestants and the Catholic Church emerged a suprisingly modern theory of individual natural rights and justified violent resistance to authority. Using ancient Roman private law concepts to justify rebellion against tyrants, Radical Calvinists such as John Ponet, Christopher Goodman, George Buchanan - all of Scotland and England, contributed, while Francois Hotman, Theodore Beza and Mornay of France transformed an essentially religious duty to resist into a secular, moral, and even natural, right of resistance.
Prior to 1530, Skinner says that Lutherans and Calvinists followed a "theory of passive political obedience" and "their leaders were almost wholly unprepared to defend their Church". Calvin thought, to oversimplify a bit, that all rulers were ordained by God, good or bad, and that man, as God's subjects, must endure the Divine Plan. Luther restated his position in 1530 - "It is in no way proper for anyone who wants to be a Christian to stand up against the authority of his government, regardless of whether that government acts rightly or wrongly".
However, a few months later, the Catholics had outlawed the Lutherans (Diet of 1530) and then Gregory Bruck, Chancellor to John of Saxony, wrote his private-law theory of resistance "Whether it is lawful to resist a judge who is proceeding unlawfully". Bruck took the view that "The Emperor is seeking to impose his judgement in matters of faith" where he "has absolutely no jurisdiction at all". Then in October, as a result of a meeting at the Palace of Torgau, Luther capitulated - "until now we have taught absolutely not to resist the governing authority [because] . . . we did not know that the governing authority's law itself grants the right of armed resistance".
Skinner says "after the immediate crisis had passed, the Lutherans not only continued to endorse the private-law theory of resistance, but even began to revise and develop it", including Luther. Here Luther smacked counter to Calvin by stating in 1539 that "The Emperor is head of the body of the political realm", and as such is "a private man to whom political power is granted for the defence of the realm". The Lutherans also developed a constitutional theory of resistance in that lesser politicos are equally ordained by God and thus can outnumber an unrighteous superior, but this theory did not develop into a natural right of resistance.
However, Skinner says "the basic argument in favour of resistance advanced by the Calvinists (during the late 1540s) . . . was largely a repetition of the Lutheran constitutonal theory". He adds "When we turn, however, from the continental leaders of Calvinism to the more revolutionary protagonists of the movement in England, we find a very different situation . . . the Scots and English revolutionaries . . . began to exploit the more individualistic and radically populist implications of the private-law argument".
Ponet and Goodman abandoned "the cardinal Augustinian assumption that, even if our rulers fail to discharge the duties of their offices, they must still be regarded as powers ordained of God". Goodman used Conciliar thinking to bring him to the conclusion that "it is lawful for the people, yea it is their duty, to do it themselves", thereby ensuring that they "cut off every rotten member" and to impose the law of God "as well upon their own rulers and magistrates as upon others of their brethren". Goodman thought God would punish anyone who did not carry out their duty, and armed thus, Calvinists revolted successfully from the Catholics.
At this point in history, "the radical Calvinists of the 1530s have no such concept of political resistance as a right" apart from a religious duty. This thinking was later accomplished "by the Huguenots during the French religious wars in the second half of the sixteenth century".
Skinner says "Since [the Huguenots]. . . were in a considerable minority, they could scarcely hope to invoke the available Calvinist theory of revolution, and demand . . . that the whole body of the godly people should rise up against the congregation of Satan in order to establish the congregation of Christ. They needed to develop a revolutionary ideology capable of appealing . . . to the various Catholic malcontents".
The French monarchy "had rendered itself so unpopular in the first half of the sixteenth century", that the Huguenots sought to appeal to the general discontent. The Huguenot monarchomachs (those who argued for the right and/or duty of subjects to resist unjust rulers), best exemplified by Francois Hotman's "Franco-Gallia"(1573), concentrated on grounding their arguments on real or presumed historical precedents in French laws and institutions resulting in a rather narrowly legal and historical argument. Their conclusions and implications were limited to promoting specific liberties of various privileged orders in French society.
Skinner says "The essence of the Huguenot case is thus that the magistrates and representatives of the people have the moral right to resist tyrannical government by force, a right which is founded on the prior and natural right of the sovereign people to treat the commonwealth as a means for securing and improving their own welfare". He concludes that "with Beza, Mornay and their followers, the idea that the preservation of religious uniformity constitutes the sole possible grounds for legitimate resistance is finally abandoned. The result is a fully political theory of revolution, founded on a recognisably modern, secularised thesis about the natural rights and original sovereignty of the people".
In summary, Skinners says that Radical Calvinism developed a secular, moral, and natural right of resistance. Yet it seems to me that they did so grudgingly and never really fully grasped natural law or natural rights. J.W. Allen noted in his "A History of Political Thought in the Sixteenth Century", p314, that the language of universal natural rights "served no Huguenot purpose. It served, in truth, no purpose at all at the time, though, one day, it might come to do so".
