sam0345 is referring to the Condemnation of 1277. I'm not sure which of the propositions he believes are true but are disbelieved by the typical Less Wronger. The list contains propositions such as the following:

• That man should not be content with authority to have certitude about any question.
• That we can know God by His essence in this mortal life.
• That God cannot know contingent beings immediately except through their particular and proximate causes.
• That eternity and time have no existence in reality but only in the mind.
• That there is more than one prime mover.
• That the elements are eternal. They were nevertheless newly produced in the disposition that they now possess.
• That the intellect is numerically one for all, for although it may be separated from this or that body, it is not separated from every body.
• That creation is not possible, even though the contrary must be held according to the faith.

I downvoted this post for whining about what would happen (without even waiting to see if it, in fact, did happen) and failing to provide arguments for any of the controversial claims found therein.
