How does Henry VIII maintain power while breaking away from the Catholic Church and destroying monasteries and churches?

Henry made himself the supreme head of the Church. This made it very easy for him to break away from Catholicism. It all started because he wanted to divorce his wife, Catherine of Aragon, because she did not give him a boy, but a girl. The Catholic Church was against divorces and annulments, and would not let him get either. He then passed the Act of Supremacy, an act in which the King was made the complete ruler and head of the Church. He was then able to divorce Catherine and marry Anne Boleyn.
