"The" Catholic Position on The Rule of Faith

An advocate for the papacy, over in the Greenbaggins comment box wrote:

And, again, whether or not the Papacy is a divine institution – the Burden of Proof is always on him who asserts. In this case, Reformed Christians and Catholic Christians both have something to prove.

The Reformed assertion: Scripture is the Rule of Faith.
The Catholic Assertion: The Church is the Rule of Faith.

I answer:

First, I thought that Mr. Anders had already agreed that Scriptures are “A” rule of faith. If so, then the only question is whether there is another rule of faith in addition. In that case, while the Reformed side may have had something to prove, that time has passed.

After all, if one concedes that the Scriptures are a rule of faith, then one has – in effect – conceded that we have met our burden. The only other assertion required to move from “Scripture is a rule of faith” to “Scripture is THE rule of faith” is the negative proposition “and we don’t have any other rule of faith.”

The burden is on the proponent of that other proposed rule of faith.

Moreover, Mr. Anders specifically asserted: “The Catholic Assertion: The Church is the Rule of Faith.”

Interestingly, Benedict XVI (Yes, I know he’s German like Kung, Rahner, and Luther, but hear me out) is reported as saying:

The word of Scripture is not “an inert deposit within the Church” but the “supreme rule of faith and power of life”. Benedict XVI wrote this in a message to participants in the annual Plenary Session of the Pontifical Biblical Commission, held from Monday, 16, to Friday, 20 April, at the Vatican’s Domus Sanctae Marthae.

L’Osservatore Romano, 21 April 2012

So, will our Roman communion friends concede what that German prelate who claims to be the successor of Peter and Paul concedes? Or do will they deny that Scripture is the supreme rule of faith?

I mean one might think that “the Catholic position” is better expressed by the pope who says: “The Church has always considered and continues to consider Sacred Scripture, together with sacred Tradition, “as the supreme rule of her faith” (DV 21) and as such she offers it to the faithful for their daily life.” (19 June 1985, General Audience)

And yes, he’s quoting from Vatican II, but I hear that they are planning on making even SSPX finally assent to those teachings.

So, what will it be? Will our Roman communion friends be on the pope’s (I suppose that should be popes’, as the 1985 audience would be the Polish prelate, not the German one) side? Do they agree that he has conceded that the Scriptures are a rule of faith and has further alleged that “Tradition” is as well?

If so, we’ve met our burden on this point – but Rome's apologists still have to meet theirs by somehow deomnstrating that their "Tradition” is to be received as the rule of faith.
