Cranmer and Ridley (at first Bishop of Rochester, and afterwards Bishop of London) were the most powerful of the clergy of this reign. Others were imprisoned and deprived of their property for still adhering to the unreformed religion; the most important among whom were Gardiner Bishop of Winchester, Heath Bishop of Worcester, Day Bishop of Chichester, and Bonner that Bishop of London who was superseded by Ridley. The Princess Mary, who inherited her mother’s gloomy temper, and hated the reformed religion as connected with her mother’s wrongs and sorrows—she knew nothing else about it, always refusing to read a single book in which it was truly described—held by the unreformed religion too, and was the only person in the kingdom for whom the old Mass was allowed to be performed; nor would the young King have made that exception even in her favour, but for the strong persuasions of Cranmer and Ridley. He always viewed it with horror; and when he fell into a sickly condition, after having been very ill, first of the measles and then of the small-pox, he was greatly troubled in mind to think that if he died, and she, the next heir to the throne, succeeded, the Roman Catholic religion would be set up again. This uneasiness, the Duke of Northumberland was not slow to encourage: for, if the Princess Mary came to the throne, he, who had taken part with the Protestants, was sure to be disgraced. Now, the Duchess of Suffolk was descended from King Henry the Seventh; and, if she resigned what little or no right she had, in favour of her daughter Lady Jane Grey, that would be the succession to promote the Duke’s greatness; because Lord Guilford Dudley, one of his sons, was, at this very time, newly married to her. So, he worked upon the King’s fears, and persuaded him to set aside both the Princess Mary and the Princess Elizabeth, and assert his right to appoint his successor. Accordingly the young King handed to the Crown lawyers a writing signed half a dozen times over by himself, appointing Lady Jane Grey to succeed to the Crown, and requiring them to have his will made out according to law. They were much against it at first, and told the King so; but the Duke of Northumberland—being so violent about it that the lawyers even expected him to beat them, and hotly declaring that, stripped to his shirt, he would fight any man in such a quarrel—they yielded. Cranmer, also, at first hesitated; pleading that he had sworn to maintain the succession of the Crown to the Princess Mary; but, he was a weak man in his resolutions, and afterwards signed the document with the rest of the council.
