6. Amidst, therefore, such great perversity of depraved opinions, we, well remembering our Apostolic Office, and very greatly solicitous for our most holy Religion, for sound doctrine and the salvation of souls which is intrusted to us by God, and (solicitous also) for the welfare of human society itself, have thought it right again to raise up our Apostolic voice. Therefore, by our Apostolic authority, we reprobate, proscribe, and condemn all the singular and evil opinions and doctrines severally mentioned in this letter, and will and command that they be thoroughly held by all children of the Catholic Church as reprobated, proscribed and condemned.

Hubris much? He is protecting us from ourselves.
