England shifted significantly towards Protestantism under King Edward VI through four phases: 1) The removal of Catholicism through closing chantries and monasteries. 2) Reforms to ceremonies through two Books of Common Prayer that outlined a Protestant liturgy and removed Catholic elements like prayers for the dead. 3) Changes to doctrine like rejecting transubstantiation and reducing Catholic influence. 4) The full establishment of Protestantism was enforced by acts requiring attendance at Church of England services, though privately some English remained Catholic in faith.
