Foiled again: some folks a bit more distinguished than you disagree:
VENERABLE POPE PIUS IX (1846-1878)And while we're at it, let's have a look at the dogmatic Council of Vatican I:
"I am only the pope. What power have I to touch the Canon?"
In response to requests that he add the name of St. Joseph to the Canon of the Mass.
"Neque enim Petri successoribus Spiritus sanctus promissus est, ut eo revelante novam doctrinam patefacerent, sed ut eo assistente traditam per apostolos revelationem seu fidei depositum sancte custodirent et fideliter exponerent. (Constitutio Dogmatica Prima de Ecclesia Christi [Pastor Aeternus], cap. 4, "De Romani Pontificis Infallibili Magisterio")And how about the great pope of the 20th century:
[For the Holy Spirit was promised to the successors of Peter not so that they might, by His revelation, make known some new doctrine, but that, by His assistance, they might religiously guard and faithfully expound the revelation or Deposit of Faith transmitted by the Apostles.
POPE PIUS XII (1939-1958)He who laughs last...
"The sacred pastors are not the inventors and composers of the Gospel, but merely the authorized guardians and preachers divinely established. Wherefore, we ourselves, and all bishops with us, can and must repat the words of Jesus Christ: "My teaching is not my own, but his who sent me" (John 7:16)....
"Therefore, we are not teachers of a doctrine born of the human mind, but we are in conscience bound to embrace and follow the doctrine which Christ Our Lord taught and which He solemnly commanded His Apostles and their successors to teach (Matthew 28:19-20)." (Encyclical Letter "Ad Sinarum Gentem," October 7, 1954)
