Section 9 of the Act of Supremacy, 1559, provided that ‘all and every Archebishoppe Bishoppe and all and every other Ecclesiasticall Person, and other Ecclesiastical Officer and Minister… and all and every Temporall Judge Justicer Mayor and other Laye or Temporall Officer and Minister’, and certain other persons should take an oath the form of which was set out in the section. The oath acknowledged the queen's ecclesiastical authority and renounced all foreign jurisdiction including that of the pope. Section 10 of the Act provided that if any person who was required to take the oath refused to do so, he should be deprived of ‘all and every Ecclesiasticall and Spiritual Promotion Benefice and Office, and every Temporall and Laye Promotion and Office’ which he had at the time of refusal, and should thereafter be disqualified for life from holding or exercising any such office or promotion.
The Act of Supremacy received the royal assent on 8 May 1559, soon after Easter, and immediately the surviving bishops of Mary's reign were faced with the prospect of taking the oath prescribed by the act. On 23 May 1559, a commission was issued to eighteen laymen authorizing and requiring them to administer the oath of supremacy to the bishops and others required by the act to take it.
