<P> On 18 November 1302 , Pope Boniface VIII issued the papal bull Unam sanctam which some historians consider one of the most extreme statements of papal spiritual supremacy ever made . The original document is lost but a version of the text can be found in the registers of Boniface VIII in the Vatican Archives . The Bull lays down dogmatic propositions on the unity of the Catholic Church , the necessity of belonging to it for eternal salvation , the position of the pope as supreme head of the Church , and the duty thence arising of submission to the pope in order to belong to the Church and thus to attain salvation . The pope further emphasizes the higher position of the spiritual in comparison with the secular order . </P>
