Henry, however, was never patient of matrimonial or other yokes, and it was quite certain that, as soon as he could do so without serious risk, he would repudiate his unattractive wife, and probably other things besides. For Anne's defects were only the last straw added to the burden which Henry bore. He had not only been forced by circumstances into marriage with a wife who was repugnant to him, but into a religious and secular policy which he and the mass of his subjects disliked. The alliance with the Protestant princes might be a useful weapon if things came to the worst, and if there were a joint attack on England by Francis and Charles; but, on its merits, it was not to be compared to a good understanding with the Emperor; and Henry would have no hesitation in throwing over the German princes when once he saw his way to a renewal of friendship with Charles. He would welcome, even more, a relief from the necessity of paying attention to German divines. He had never wavered in his adhesion to the cardinal points of the Catholic faith. He had no enmity to Catholicism, provided it did not stand in his way. The spiritual jurisdiction of Rome (p. 387) had been abolished in England because it imposed limits on Henry's own authority. Some of the powers of the English clergy had been destroyed, partly for a similar reason, and partly as a concession to the laity. But the purely spiritual claims of the Church remained unimpaired; the clergy were still a caste, separate from other men, and divinely endowed with the power of performing a daily miracle in the conversion of the bread and wine into the Body and Blood of Jesus Christ. Even when the Protestant alliance seemed most indispensable, Henry endeavoured to convince Lutherans of the truth of the Catholic doctrine of the mass, and could not refrain from persecuting heretics with a zeal that shook the confidence of his reforming allies. His honour, he thought, was involved in his success in proving that he, with his royal supremacy, could defend the faith more effectively than the Pope, with all his pretended powers; and he took a personal interest in the conversion and burning of heretics. Several instances are recorded of his arguing a whole day with Sacramentaries,[1077] exercises which exhibited to advantage at once the royal authority and the royal learning in spiritual matters. His beliefs were not due to caprice or to ignorance; probably no bishop in his realm was more deeply read in heterodox theology.[1078] He was constantly on the (p. 388) look-out for books by Luther and other heresiarchs, and he kept quite a respectable theological library at hand for private use. The tenacity with which he clung to orthodox creeds and Catholic forms was not only strengthened by study but rooted in the depths of his character. To devout but fundamentally irreligious men, like Henry VIII. and Louis XIV., rites and ceremonies are a great consolation;
