The Elizabethan Settlement in England was broken in 1570 with the excommunication of Elizabeth. Although few, if any, concessions were made to the Papacy or to Roman Catholic doctrine, a small number of changes were then made to the Articles of Religion and to the Prayer Book, especially in relation the Real Presence and to the continuation of worship in more traditional forms. Only one of Mary's English and Welsh bishops conformed to the Elizabethan settlement, though all save 300 of the parish clergy subscribed. In Ireland the position was reversed; all bishops save two accepted the Elizabethan Settlement, but the bulk of parish clergy and laity remained loyal to the pope. In the period since 1553, Continental Reformed Protestantism had itself continued to develop, especially in Geneva and Heidelberg, but English divines who wished the Elizabethan church to take part in these developments were to be bitterly disappointed; Elizabeth refused any further change to the forms or structures of religion established in 1559. In particular, Protestant controversialists began to attack the episcopal polity, and the defined liturgy of the Elizabethan Church as incompatible with the true Reformed tradition; and, in response, defenders of the established church began, from the early 17th Century onwards, to claim these specific features as positively desirable, or indeed essential.
