ambassadors and the Bishop of Durham. While the sermon was being preached, numbers of Lutheran books were burnt in a huge bonfire kindled hard by in St. Paul's Churchyard.[386] The representatives of Pope and Emperor saw it all, and doubtless reported to their respective Courts that Wolsey was doing his duty by Church and Empire. It may be doubted whether such theatrical exhibitions hindered the spread of Luther's books in England or prevented them being read. All these things indicated a certain preparedness in England for the Reformation, and all meant that there was a strong national force behind Henry VIII. when he at last made up his mind to defy Rome. Nor was a national separation from Rome so formidable an affair as Dr. Gairdner would have us believe. The Papacy had secularised itself, and European monarchs were accustomed to treat the Popes as secular princes. The possibility of England breaking away from papal authority and erecting itself into a separate patriarchate under the Archbishop of Canterbury had been thought probable before the divorce was talked about.[387] It was Henry himself who clung strenuously to the conception of papal supremacy, and who advocated it in a manner only done hitherto by canonists of the Roman Curia. Whatever be the secret reason which he gave to Sir Thomas More, and which silenced the latter's remonstrances, it is evident that the validity of Henry's marriage and the legitimacy of his children by Catharine of Aragon depended on the Pope being in possession of the very fullest powers of dispensation. Henry had been married to Catharine under very peculiar circumstances, which might well suggest doubts about the validity of the marriage ceremony.
