exceeded their lawful limits, they might be resisted, even by force. On 13 December 1562, Mary sent for Knox again after he gave a sermon denouncing certain celebrations which Knox had interpreted as rejoicing at the expense of the Reformation. She charged that Knox spoke irreverently of the Queen in order to make her appear contemptible to her subjects.
