"The proposition that the Earth is not the center of the world and immovable but that it moves, and also with a diurnal motion, is equally absurd and false philosophically and theologically considered at least erroneous in faith." (Papal condemnation of Galileo, 1633)
"“For this purpose,…[ pursues the Pontiff]…we have caused the Tridentine and Clementine Indices to be added to this general Index, and also all the relevant decrees up to the present time, that have been issued since the Index of our predecessor Clement, that nothing profitable to the faithful interested in such matters might seem omitted. Since then all these directions have been faithfully and accurately carried out, and a general Index of this kind has been composed,—to which also the rules of the Tridentine Index, with the observations and instructions added to the Clementine Index, have been prefixed; this same general Index as it is put forth, composed by our order, revised, and printed at the press of our Apostolic Camera, and which we will should be considered as though it were inserted in these presents, together with all, and singular, the things contained therein, we, having taken the advice of our Cardinals, confirm, and approve with Apostolic authority by the tenor of these presents, and: command and enjoin all persons everywhere to yield this Index a constant and complete obedience…" (Pope Alexander VII, Speculatores Dominus Israel, 1664.
