The number of heretics and sectaries of different sorts is uncertain. In 1550 the name of Thomas Broke occurs among the chief sectaries of Kent. He controverted and denounced John Lilburne, and called on Parliament to crush the sectaries. Brabourne wrote in 1653 "The Change of Church-Discipline", a tract against sectaries of all sorts. Opposition from Independents and sectaries, however, meant that the ordinance was never enforced. He proposed and had passed the Seditious Sectaries Act 1593, thus making Puritanism an offence. The Seditious Sectaries Act of 1593 was specifically aimed at outlawing the Brownists.
