Not trying to be contrary but this IS what was said in the Papal bull Unam Sanctum:
"Now, therefore, we declare, say, determine and pronounce that for every human creature it is necessary for salvation to be subject to the authority of the Roman pontiff" (Porro subesse Romano Pontifici omni humanae creaturae declaramus, dicimus, definimus, et pronuntiamus omnino esse de necessitate salutis).
The Bull is universal in character. As its content shows, a careful distinction is made between the fundamental principles concerning the Roman primacy and the declarations as to the application of these to the secular power and its representatives. In the registers, on the margin of the text of the record, the last sentence is noted as its real definition: "Declaratio quod subesse Romano Pontifici est omni humanae creaturae de necessitate salutis" (It is here stated that for salvation it is necessary that every human creature be subject to the authority of the Roman pontiff). This definition, the meaning and importance of which are clearly evident from the connection with the first part on the necessity of the one Church for salvation, and on the pope as the one supreme head of the Church, expresses the necessity for everyone who wishes to attain salvation of belonging to the Church, and therefore of being subject to the authority of the pope in all religious matters. This has been the constant teaching of the Church, and it was declared in the same sense by the Fifth Ecumenical Council of the Lateran, in 1516: "De necessitate esse salutis omnes Christi fideles Romano Pontifici subesse" (That it is of the necessity of salvation for all Christ's faithful to be subject to the Roman pontiff).

Finally, since the faithful have voluntarily sought membership in the Christian society they are bound to submit to its authority and obey its rulers. As to the rights of the faithful, they consist chiefly in the fullest participation in all the Christian mysteries, so long as one does not become unworthy of the same. Thus the faithful Christian is entitled to take part in the Holy Sacrifice, to remain in the assembly after the deacon has sent away the catechumens, to offer up with the priest the orate fidelium or prayer of the faithful, to receive there the Body and Blood of Christ, and to receive the other rites and sacraments. He may also aspire to the highest rank of the clergy. In a word, he is a full member of the Christian society, and is such, regularly speaking, in perpetuity. If by reason of his own misdeeds he deserves to be expelled from said society, repentance and the reparatory penitential rite, a second baptism, as it were, permit his return. Finally, if he persist in the observance of his baptismal promises, he will obtain eternal life, i.e. his original petition at the moment of baptism. (http://www.newadvent.org/cathen/05769a.htm
