Pope Boniface VIII, in Unam Sanctam, stated: “Now, therefore, we declare, say, define, and pronounce that for every human creature it is altogether necessary for salvation to be subject to the authority of the Roman pontiff.”
Scripture, in contrast, gives universal jurisdiction to Christ alone: “the blessed and only Potentate, the King of kings, and Lord of lords” (1 Timothy 6:15) and the Psalmist declares: “Thou madest him to have dominion over the works of thy hands; thou hast put all things under his feet” (Psalm 8:6) which the Apostle tells us plainly refers to Christ: “And hath put all things under his feet, and gave him to be the head over all things to the church” (Ephesians 1:22).
