Why at first was Henry viii worried about Luther and the Protestant?

Henry VIII was initially worried about Martin Luther and the Protestant Reformation because it threatened the established Catholic Church, which was closely tied to the authority of the monarchy in England. Luther's challenges to papal authority and the promotion of individual interpretation of the Scriptures undermined the traditional power structures that supported Henry’s rule. Additionally, as a devout Catholic, Henry sought to defend the Church and its teachings, leading him to write "Defence of the Seven Sacraments" against Luther's ideas, which earned him the title "Defender of the Faith" from the Pope.
