Sir Thomas More (7 February 1478 - 6 July 1535), venerated in the Catholic Church as Saint Thomas More, was an English lawyer, social philosopher, author, statesman, and noted Renaissance humanist. He was also a Chancellor to Henry VIII, and Lord High Chancellor of England from October 1529 to 16 May 1532. He wrote Utopia, published in 1516, about the political system of an imaginary, ideal island nation. More opposed the Protestant Reformation, directing polemics against the theology of Martin Luther, John Calvin and William Tyndale. More also opposed King Henry VIII's separation from the Catholic Church, refusing to acknowledge Henry as Supreme Head of the Church of England and the annulment of his marriage to Catherine of Aragon. After refusing to take the Oath of Supremacy, he was convicted of treason and executed. Of his execution, he was reported to have said: "I die the King's good servant, and God's first." Pope Pius XI canonized More in 1935 as a martyr. Pope John Paul II in 2000 declared him the patron saint "of Statesmen and Politicians." Since 1980, the Church of England has remembered More liturgically as a Reformation martyr. Praised by Marx and Engels, the Soviet Union in the early twentieth century honored him for the purportedly communist attitude toward property rights expressed in Utopia.
