The sword was drawn in the first of a series of penal statutes which weighed upon English Catholics for two hundred years. By this statute an oath of allegiance to the Queen and of abjuration of the temporal authority of the Pope was exacted from all holders of office, lay or spiritual, within the realm, with the exception of peers. Its effect was to place the whole power of the realm in the hands either of Protestants or of Catholics who accepted Elizabeth's legitimacy and her ecclesiastical jurisdiction in the teeth of the Papacy. The oath of supremacy was already exacted from every clergyman and every member of the universities. But the obligation of taking it was now widely extended. Every member of the House of Commons, every officer in the army or the fleet, every schoolmaster and private tutor, every justice of the peace, every municipal magistrate, to whom the oath was tendered, was pledged from this moment to resist the blows which Rome was threatening to deal. Extreme caution indeed was used in applying this test to the laity, but pressure was more roughly put on the clergy. A great part of the parish priests, though they had submitted to the use of the Prayer-Book, had absented themselves when called on to take the oath prescribed by the Act of Uniformity, and were known to be Catholics in heart. As yet Elizabeth had cautiously refused to allow any strict enquiry into their opinions. But a commission was now opened by her order at Lambeth, to enforce the Act of Uniformity in public worship; while thirty-nine of the Articles of Faith drawn up under Edward the Sixth, which had till now been left in suspense by her Government, were adopted in Convocation as a standard of faith, and acceptance of them demanded from all the clergy.
