Various Popes speaking Ex Cathedra...

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.”2

I have never understood how one can name themselves Catholic and NOT be entirely subject to the Roman Pontiff

As a child were you not subject to your parents? And at one time or another did you not disobey your parents?

Out of curiosity, on what basis do you asset that Unam Sanctam was/is an ex-cathedra statement? Is there an official list of documents formally recognized by Rome as having this distinction?
