[marshmallow]

"For the Holy Spirit was not given to the Successors of Peter that by His revelation they might disclose new doctrine, but that by His help they might guard the revelation transmitted through the apostles and the deposit of faith." In other words, only papal utterances which guard Tradition have divine protection, novelties do not.

A completely erroneous interpretation of this passage from Vatican I. Is that your personal exegesis or was this fed to you from the pulpit?

The passage says the following.

1) The Holy Spirit has been given to the successor of Peter.

2) The Holy Spirit does not reveal new doctrine.

3)The Holy Spirit assists the successor of Peter.

3)This assistance allows the successor of Peter to guard "the revelation that has been transmitted through the apostles", rather than define new doctrine.

What you would like to twist this into saying is that you get to decide whether Papal utterances are in accord with tradition. That's Protestantism. And you are a Protestant.

Your reading comprehension is apparently as deficient as your theology. The Vatican I statement says the following:

1. The protection of the Holy Spirit wasn't granted so that popes might go off on tangents proclaiming new doctrines.

2. His revelation is granted only to GUARD what has been handed-down to us from the apostles and the deposit of faith.

In other words, it's the job of popes to GUARD TRADITION, not to invent new doctrines of the kind JPII seems to do every other week.
