text: Well I believe any teaching or dogma that no one has disputed is true, among the Bishops, would hold- such as the divinity of Christ, as the Son of God.   Any dogma long held as true without any disagreement of bishops and then voted on unanimously as infallible could hold too.   By and large both popes and bishops try to avoid making official infallible dogma determinations even on things they truly believe are absolutely true for the very reasons which you gave.  Why pin yourself to something that strongly when it is not necessary and most people and bishops are in agreement without going infallible.  No one wants the mistake of declaring things infallible that maybe God didn't want and then have to face God later on.
