Agree 100%, as long as it is understood that here, it is the Church that is the Divinely instituted Teacher, not the pope.

And so, supported by the clear witness of Holy Scripture, and adhering to the manifest and explicit decrees both of our predecessors the Roman Pontiffs and of general councils, we promulgate anew the definition of the ecuмenical Council of Florence, which must be believed by all faithful Christians, namely that the "holy Apostolic See and the Roman Pontiff hold a world-wide primacy, and that the Roman Pontiff is the successor of blessed Peter, the prince of the apostles, true vicar of Christ, head of the whole Church and father and teacher of all Christian people. To him, in blessed Peter, full power has been given by our lord Jesus Christ to tend, rule and govern the universal Church. All this is to be found in the acts of the ecuмenical councils and the sacred canons."
...
That apostolic primacy which the Roman Pontiff possesses as successor of Peter, the prince of the apostles, includes also the supreme power of teaching.
...
Then there is the definition of the Council of Florence: "The Roman Pontiff is the true vicar of Christ, the head of the whole Church and the father and teacher of all Christians; and to him was committed in blessed Peter, by our lord Jesus Christ, the full power of tending, ruling and governing the whole Church."
...
[T]heir [the Popes'] apostolic teaching was embraced by all the venerable fathers and reverenced and followed by all the holy orthodox doctors, for they knew very well that this See of St. Peter always remains unblemished by any error, in accordance with the divine promise of our Lord and Savior to the prince of his disciples: "I have prayed for you that your faith may not fail; and when you have turned again, strengthen your brethren."

Vatican I teaches otherwise.

So NOW you "agree", after rejecting my having said the very same thing.  Of course, then you slap on that non-Catholic (aka heretical) qualifier.

Vatican I: Pastor Aeternus
So your opinion is heretical, the assertion that the Pope is not "the Divinely Instituted Teacher".

Note also the last part which states that the See of Peter remains "unblemished by any error".  Good luck with that one, Stubborn.

This further backs up my repeated assertion that your ecclesiology is nothing short of heretical.
