In this pro-Protestant, anti-Catholic environment, the Puritan faction sought to push further reforms on the Church of England.
John Foxe and Thomas Norton presented a reform proposal initially drawn up under Edward VI to Parliament. Elizabeth quickly dismissed this proposal, however, insisting on adherence to the 1559 religious settlement.
Meanwhile, at Cambridge, professor Thomas Cartwright, a long-time opponent of vestments, offered a series of lectures in 1570 on the Book of Acts in which he called for the abolition of episcopacy and the creation of a presbyterian system of church governance in England.
Under these circumstances, in 1572, two London clergymen - Thomas Wilcox and John Field - penned the first classic expression of Puritanism, their Admonition to the Parliament. According to the Admonition, the Puritans had long accepted the Book of Common Prayer, with all its deficiencies, because it promoted the peace and unity of the church.
Elizabeth ordered Parliament not to deal with matters of Religion, she didn't want to break the central system that was appealing to most people, however, she did need to beat the Militant catholicism that was emerging, with Jesuits and the Council of Trent making an appearance.
