Pope Boniface VIII, Unam Sanctam, Nov. 18, 1302, EX CATHEDRA: “With Faith urging us we are forced to believe and to hold the one, holy, Catholic Church and that, apostolic, and we firmly believe and simply confess this Church outside of which there is no salvation nor remission of sin… Furthermore, we declare, say, define, and proclaim to every human creature that they by absolute necessity for salvation are entirely subject to the Roman Pontiff.”
CCC Part 1, Section 2, Paragraph 3, 819: "…Christ’s Spirit uses these Churches and ecclesial communities as means of salvation, whose power derives from the fullness of grace and truth that Christ has entrusted to the Catholic Church. All these blessings come from Christ and lead to him and are in themselves calls to “Catholic unity.”
Despite the misconception often held by people who are only familiar with its last sentence,
Unam sanctam was about a controversy between Catholics as to political and ecclesiastical authority; it had nothing to do whatsoever with non-Catholic religions and doesn’t discuss them in any way. As I
previously wrote on this topic:
One must also understand what the bull
Unam sanctam was actually about. Boniface VIII didn’t just wake up one day and decide to declare that non-Catholics can’t be saved. In fact,
Unam sanctam has nothing to do with non-Catholics at all!
The bull was part of a fierce and longrunning political dispute between Boniface, a rather impolitic pope, and Philip the Fair of France, who wanted to tax the clergy and exert more control over religious institutions. Two two traded diplomatic barbs for several years: Philip sought to try the bishop of Pamiers for treason; Boniface shot back the condescending bull
Ausculta Fili (“Now you listen to me, kiddo”).
Eventually Boniface issued
Unam sanctam. Again, it has nothing whatsoever to do with non-Catholics. Everyone involved here was Catholic. It is about the relationship between temporal rulers, like kings, and the spiritual authorities. So he writes:
*t is a law of the divinity that the lowest things reach the highest place by intermediaries. . . . Hence we must recognize the more clearly that spiritual power surpasses in dignity and in nobility any temporal power whatever, as spiritual things surpass the temporal.
. . .
Therefore, if the terrestrial power err, it will be judged by the spiritual power; but if a minor spiritual power err, it will be judged by a superior spiritual power; but if the highest power of all err, it can be judged only by God, and not by man . . . . Therefore whoever resists this power thus ordained by God, resists the ordinance of God.
That, in a nutshell, is what the bull is about. Now, it would be quite strange for Boniface to have written a whole bull about the hierarchy of temporal and religious authorities, and then to tack on as a total afterthought the dogma that some think they see here: “Oh yeah, and by the way, apropos of nothing, everybody in the world must be a Catholic to be saved. Just thought I’d throw that out there.”
This is not to say that it isn’t true that people must be Catholic to be saved – what do I know? – only that Unam sanctam is simply about a totally different topic altogether. So phrases like “be subject to the Roman Pontiff” have to be understood in terms of what Boniface was actually trying to do with the bull and the message he was attempting to communicate about temporal authority; it’s misleading if we try to pretend he was writing this on a completely different subject matter.
Oh, and by the way, after this, Boniface excommunicated Philip, who then sent mercenaries to attack him and plunder his palace. Boniface died a month later from the trauma. It’s easy to read the high-sounding and rather bombastic language of Unam sanctam and think, “Wow, those were the days! What majestic papal power!” In fact, this period was a real nadir of papal authority, from which it would never fully recover.
