Prohibiting with a strong hand the use of the true religion, which after its earlier overthrow by Henry VIII (a deserter therefrom) Mary, the lawful queen of famous memory, had with the help of this See restored, she [ELIZABETH] has followed and embraced the errors of the heretics. She has removed the royal Council, composed of the nobility of England, and has filled it with obscure men, being heretics; oppressed the followers of the Catholic faith; instituted false preachers and ministers of impiety; abolished the Sacrifice of the Mass, prayers, fasts, choice of meats, celibacy, and Catholic ceremonies; and has ordered that books of manifestly heretical content be propounded to the whole realm and that impious rites and institutions after the rule of Calvin, entertained and observed by herself, be also observed by her subjects. She has dared to eject bishops, rectors of churches and other Catholic priests from their churches and benefices, to bestow these and other things ecclesiastical upon heretics, and to determine spiritual causes; has forbidden the prelates, clergy and people to acknowledge the Church of Rome or obey its precepts and canonical sanctions; has forced most of them to come to terms with her wicked laws, to abjure the authority and obedience of the pope of Rome, and to accept her, on oath, as their only lady in matters temporal and spiritual; has imposed penalties and punishments on those who would not agree to this and has exacted then of those who persevered in the unity of the faith and the aforesaid obedience; has thrown the Catholic prelates and parsons into prison where many, worn out by long languishing and sorrow, have miserably ended their lives. All these matter and manifest and notorious among all the nations; they are so well proven by the weighty witness of many men that there remains no place for excuse, defense or evasion.
