Papal Bull Unam Sanctam
“Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff.”
And you know the funny part?
I’m a human creature
It’s necessary for salvation to be subject to the Roman Pontiff
I’m not his subject nor in communion with him
Ok, that is the quote I thought you were referring to. Yes, you are a human creature, and since the Roman Pontiff is the successor of Peter, who was given responsibility for the flock of God, all who are members of the flock of God are subject to him. You most certainly ARE a subject of the Roman Pontiff, if you are a baptized member of the Church founded by Christ. I will grant that you are a rebellious subject, but a subject nonetheless.
Just as Christ is Lord of the heavens and the earth, not all who dwell in the earth recognize His lordship, but such denial does not in any way detract from the fact that He is Lord.
In the same way, the successor of Peter who has been given the charge to feed and care for the flock is responsible for all the sheep, whether they know it or not, and whether they acknowledge it or not.
