In regard to the legal and canonical requirements, the government was at pains to see all were met for the consecration. None of the 18 Marian bishops would agree to consecrate Parker. Not only were the opposed to the changes the bishops had been excluded from decision-making regarding changes in liturgy, doctrine and the Royal Supremacy. The Commons approved the changes and the Lords 21-18 approved after pressure was brought to bear on them; concessions were made in a more Catholic tone in eucharistic doctrine, and allowance made for the use of Mass vestments and other traditional clerical dress in use in the second year of the reign of Edward VI, i.e. January 1548 to 49, when the Latin Rite was still the legal form of worship (the 'Ornaments Rubric' in the 1559 Prayer Book seems to refer to the allowance as set forth in the 1549 BCP).
