When first arrested he was terrified: he acknowledged his offences, submitted, and was pardoned. But his conscience recovered its strength: he returned to his loyalty to the Papacy; he declared his belief that, in matters spiritual, the Pope was his proper sovereign, that the Bishop of Rochester was a martyr, as Thomas à Becket had been a martyr. Becket he held up as the pattern of all churchmen's imitation, courting for himself Becket's fortunes.[358] Like others, he attempted a distinction in the nature of allegiance. "In matters secular his duty was to his prince." But, on the threshold of the exception lay the difficulty which no Catholic could evade,--what was the duty of a subject when a king was excommunicated, and declared to have forfeited his crown? Forest, therefore, fell justly under the treason law. But, inasmuch as Catholic churchmen declared the denial of the Pope's supremacy to be heresy, so, for a few unfortunate months, English churchmen determined the denial of the king's supremacy to be heresy; Forest was to be proceeded against for an offence against spiritual truth as well as a crime against the law of the land; and Cranmer is found corresponding with Cromwell on the articles on which he was to be examined.[359] I do not know that the document which I am about to quote was composed for this special occasion. For the first, and happily the last time, the meaning of it was acted upon. [Sidenote: Anglican definition of heresy, which is extended to a denial of the royal supremacy.] [Sidenote: Forest is sentenced to death.] In an official paper of about this date, I find "heresy" defined to be "that which is against Scripture." "To say, therefore, that Peter and his successors be heads of the universal Church, and stand stubbornly in it, is heresy, because it is against Scripture (Ecclesiastes v.); where it is written, 'Insuper universæ terræ rex imperat servienti'--that is to say, the king commandeth the whole country as his subjects; and therefore it followeth that the Bishop of Rome, which is in Italy where the Emperor is king, is subject to the Emperor, and that the Emperor may command him; and if he should be head of the universal Church, then he should be head over the Emperor, and command the Emperor, and that is directly against the said text, Ecclesiastes v. Wherefore, to stand in it opiniatively is heresy."[360] In the spirit, if not in the letter of this monstrous reasoning, Forest was indicted for heresy in a court where we would gladly believe that Cranmer did not sit as president. He was found guilty, and was delivered over, in the usual form, to the secular arm. [Sidenote: The image of Dderfel Gadern.]
