Which examples the fact that while evangelicals are attacked for interpreting their supreme authority differently, so do RCs, with some see RC teaching as censuring dissent from the pope such as we see here (which censure is indeed taught), while some saying that this is why such a heretical pope cannot be a valid pope, while others say it is not for them to question such, but to simply follow leadership.
Even then you have the fact that there are different classes of magisterial teaching, which, besides being open to varying degrees of interpretation, require different degrees of assent relative to their certainty.
Faced with such one poster (from a Catholic Answers thread) sighed, Boy. No disrespect intended...and I mean that honestly...but my head spins trying to comprehend the various classifications of Catholic teaching and the respective degrees of certainty attached thereto. I suspect that the average Catholic doesn't trouble himself with such questions, but as to those who do (and us poor Protestants who are trying to get a grip on Catholic teaching) it sounds like an almost impossible task.
The solution for which is cultic, just obey and don't question:
Praxis [practice] is quite simple for faithful Catholics: give your religious assent of intellect and will to Catholic doctrine, whether it is infallible or not. That's what our Dogmatic Constitution on the Church demands, that's what the Code of Canon Laws demand, and that is what the Catechism itself demands. Heb 13:17 teaches us to "obey your leaders and submit to them." This submission is not contingent upon inerrancy or infallibility. - http://forums.catholic.com/showthread.php?p=1565864#post1565864
Thus cultic implicit faith is called for, otherwise you have the reality of disparate understandings of RC teaching that we see now, which is contrary to what Rome expresses as reality but which is really only wishful thinking:
CCC 889 In order to preserve the Church in the purity of the faith handed on by the apostles, Christ who is the Truth willed to confer on her a share in his own infallibility. By a "supernatural sense of faith" the People of God, under the guidance of the Church's living Magisterium, "unfailingly adheres to this faith."
And it was the claim of the Reformation that Rome had strayed away from the "supernatural sense of faith" once delivered unto the saints as recorded in the holy word of God, Sacred Scriptures. I don't believe Christ ever intended us to blindly follow those placed in leadership roles in the church but that ALL must be held to the standards of the faith as handed down and taught by the Apostles of Jesus. Catholicism cannot produce even a single article of faith or verifiable words from the Apostles outside of what was written in Scripture. The claim that "Sacred Tradition" is equal in authority to Sacred Scripture is wrong - it can't be.
