Isn't that kinda what Boniface VIII was getting at with Unam Sanctum?
"Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff."
The Bull also states, "We are informed by the texts of the gospels that in this Church and in its power are two swords; namely, the spiritual and the temporal."[12] The swords being referred to are a customary reference to the swords yielded by the Apostles upon Christ's arrest (Luke 22:38; Matthew 26:52).[2] Early theologians believed that if there are two swords, one must be subordinate to the other. This then became a spiritual hierarchal ladder, the spiritual judges the secular "on account of its greatness and sublimity,[2] while the lower spiritual power is judged by the higher spiritual power, etc.[11] Thus, it was concluded, the temporal authorities must submit to the spiritual authorities, not merely on matters concerning doctrine and morality: "For with truth as our witness, it belongs to spiritual power to establish the terrestrial power and to pass judgment if it has not been good." The bull ends, "Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff."[12] In the bull, Boniface reiterates what popes since the time of Pope Gregory VII had been declaring.[13] Much of what is said can be taken from the writings of Bernard of Clairvaux, Hugh of Saint Victor, and Thomas Aquinas.[2] The bull also contains writing from the letters of Pope Innocent III, who mainly reasserted the spiritual power and the "plenitudo potestatis" of the papacy.[13] A voice heavily noticed in the bull is Giles of Rome, who some hold might have been the actual writer of the bull.[14][page needed] Giles, in On Ecclesiastical Power, voices the supremacy of the Roman Pontiff over the material world. His line of argument states that since the body is governed by the soul and the soul is governed by the ruler of the spiritual, the Roman Pontiff therefore is governor of both soul and body.https://en.wikipedia.org/wiki/Unam_sanctam
Which interpretation is typical of Cath exegesis, in which the gospels are treated as self-interpreting, and as being interpretive of the rest of the NT, rather than the latter being interpretive of the former, as is the case with the OT, though taking both together is needed for proper understanding of the will and ways of God.
Thus we understand the atonement of Christ in the light of the OT, but the meaning of the latter is revealed in the subsequent Divine revelation of the New.
In this issue, nowhere do we see a prophetic meaning of the two sword as in the church and state, and instead we nowhere see the church ruling over those without by making the state its instrument to deal with theological and spiritual matters, and we even have statements contrary to this taking of two swords, beginning in the gospels:
They say unto him, Cæsar's. Then saith he unto them, Render therefore unto Cæsar the things which are Cæsar's; and unto God the things that are God's. (Matthew 22:21)
Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence. (John 18:36)
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (Ephesians 6:12)
For though we walk in the flesh, we do not war after the flesh: (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) (2 Corinthians 10:3-4)
For what have I to do to judge them also that are without? do not ye judge them that are within? But them that are without God judgeth. Therefore put away from among yourselves that wicked person. (1 Corinthians 5:12-13)
