On 18 April, an order was issued that all citizens of London were to swear their acceptance of the Oath of Succession. Similar orders were issued throughout the country. When Parliament reconvened in November, Cromwell brought in the most significant revision of the treason laws since 1352, making it treasonous to speak rebellious words against the Royal Family, to deny their titles, or to call the King a heretic, tyrant, infidel, or usurper. The Act of Supremacy also clarified the King's position as head of the church and the Act for Payment of First Fruits and Tenths substantially increased clerical taxes. Cromwell also strengthened his own control over the Church. On 21 January 1535, the King appointed him Royal Vicegerent and Vicar-General, and commissioned him to organise visitations of all the country's churches, monasteries, and clergy. In this capacity, Cromwell conducted a census in 1535 to enable the government to tax church property more effectively.
