After the prorogation, Sir Thomas More, the chancellor, foreseeing that all the measures of the king and parliament led to a breach with the church of Rome, and to an alteration of religion, with which his principles would not permit him to concur, desired leave to resign the great seal; and he descended from his high station with more joy and alacrity than he had mounted up to it. The austerity of this man’s virtue, and the sanctity of his manners, had no wise encroached on the gentleness of his temper, or even diminished that frolic and gaiety, to which he was naturally inclined. He sported with all the varieties of fortune into which he was thrown; and neither the pride, naturally attending a high station, nor the melancholy incident to poverty and retreat, could ever lay hold of his serene and equal spirit. While his family discovered symptoms of sorrow on laying down the grandeur and magnificence, to which they had been accustomed, he drew a subject of mirth from their distresses; and made them ashamed of losing even a moment’s chearfulness, on account of such trivial misfortunes. The king, who had entertained a high opinion of his virtue, received his resignation with some difficulty; and he delivered the great seal soon after to Sir Thomas Audley....
The oath regarding the succession was generally taken throughout the kingdom. Fisher, bishop of Rochester, and Sir Thomas More, were the only persons of note, that entertained scruples with regard to its legality. Fisher was obnoxious on account of some practices, into which his credulity, rather than any bad intentions, seems to have betrayed him. But More was the person of greatest reputation in the kingdom for virtue and integrity; and as it was believed, that his authority would have influence on the sentiments of others, great pains were taken to convince him of the lawfulness of the oath. He declared, that he had no scruple with regard to the succession, and thought that the parliament had full power to settle it: He offered to draw an oath himself, which would ensure his allegiance to the heir appointed; but he refused the oath prescribed by law; because the preamble of that oath asserted the legality of the king’s marriage with Anne, and thereby implied, that his former marriage with Catherine was unlawful and invalid. Cranmer, the primate, and Cromwel, now secretary of state, who highly loved and esteemed More, entreated him to lay aside his scruples; and their friendly importunity seemed to weigh more with him, than all the penalties attending his refusal. He persisted, however, in a mild, though firm manner, to maintain his resolution; and the king, irritated against him as well as Fisher, ordered both to be indicted upon the statute, and committed prisoners to the Tower....
John Fisher, bishop of Rochester, was a prelate, eminent for learning and morals, still more than for his ecclesiastical dignities, and for the high favour, which he had long enjoyed with the king. When he was thrown into prison, on account of his refusing the oath which regarded the succession, and his concealment of Elizabeth Barton’s treasonable speeches, he had not only been deprived of all his revenues, but stripped of his very cloaths, and, without consideration of his extreme age, he was allowed nothing but rags, which scarcely sufficed to cover his nakedness. In this condition, he lay in prison above a twelvemonth; when the pope, willing to recompense the sufferings of so faithful an adherent, created him a cardinal; though Fisher was so indifferent about that dignity, that, even if the purple were lying at his feet, he declared that he would not stoop to take it. This promotion of a man, merely for his opposition to royal authority, rouzed the indignation of the king; and he resolved to make the innocent person feel the effects of his resentment. Of Sir Thomas More. Fisher was indicted for denying the king’s supremacy, was tried, condemned, and beheaded.
The execution of this prelate was intended as a warning to More, whose compliance, on account of his great authority both abroad and at home, and his high reputation for learning and virtue, was anxiously desired by the king. That prince also bore as great personal affection and regard to More, as his imperious mind, the sport of passions, was susceptible of towards a man, who in any particular opposed his violent inclinations. But More could never be prevailed on to acknowledge any opinion so contrary to his principles as that of the king’s supremacy; and though Henry exacted that compliance from the whole nation, there was, as yet, no law obliging any one to take an oath to that purpose. Rich, the solicitor general, was sent to confer with More, then a prisoner, who kept a cautious silence with regard to the supremacy: He was only inveigled to say, that any question with regard to the law, which established that prerogative, was a two-edged sword: If a person answer one way, it will confound his soul; if another, it will destroy his body. No more was wanted to sound an indictment of high treason against the prisoner. His silence was called malicious, and made a part of his crime; and these words, which had casually dropped from him, were interpreted as a denial of the supremacy.y Trials were mere formalities during this reign: The jury gave sentence against More, who had long expected this fate, and who needed no preparation to fortify him against the terrors of death. Not only his constancy, but even his cheerfulness, nay, his usual facetiousness, never forsook him; and he made a sacrifice of his life to his integrity with the same indifference that he maintained in any ordinary occurrence. When he was mounting the scaffold, he said to one, "Friend, help me up, and when I come down again, let me shift for myself." The executioner asking him forgiveness, he granted the request, but told him, "You will never get credit by beheading me, my neck is so short." Then laying his head on the block, he bade the executioner stay till he put aside his beard: "For," said he, "it never committed treason." Nothing was wanting to the glory of this end, except a better cause, more free from weakness and superstition. But as the man followed his principles and sense of duty, however misguided, his constancy and integrity are not the less objects of our admiration. He was beheaded in the fifty-third year of his age.
That's a bit long, but I think it's interesting enough to warrant it. Jennifer Herdt, in her wonderful Religion and Faction in Hume's Moral Philosophy, notes that this appraisal of Thomas More is something of an anomaly for Hume's view on the psychology of religion. Generally speaking, Hume holds that (monotheistic, and particularly institutional monotheistic) religion induces an 'artificial life' -- an unnatural way of living -- that is characterized by gloom, hypocrisy, and irrationality. These make sympathetic understanding impossible; they interfere with an outsider's ability to put themselves in the religionist's shoes. The only understanding available is to identify causes external to the religious viewpoint (supposedly) affirmed: secret motives, passions, political factions. The religious viewpoint in itself is incomprehensible. None of these apply to More, however. As Herdt notes:
The virtues of constancy and integrity are hardly those which Hume should in theory discover in a theist, even the most sincere. So Hume in this instance seems to give the lie to his own assumptions about the nature of theistic belief and therefore to the limits of sympathetic understanding of a theist by a non-theist.[Jennifer Herdt, Religion and Faction in Hume's Moral Philosophy. Cambridged (1997) p. 214]
So Hume's account of religion has no place for people like More. Of course, as Herdt goes on to note, Hume's account of religion, insofar as it is directed at anybody, is directed at the very narrow Scottish Calvinism that Hume knew growing up; and seen in this light a lot can still be said for Hume's account. The anomaly of More isn't a counterexample for the account, strictly speaking; it just marks a way in which it is limited.
