Pope Pius VIII says:
"We must also be wary of those who publish the Bible with new interpretations contrary to the Church's laws. They skillfully distort the meaning by their own interpretation. They print the Bibles in the vernacular and, absorbing an incredible expense, offer them free even to the uneducated.
Furthermore, the Bibles are rarely without perverse little inserts to ensure that the reader imbibes their lethal poison instead of the saving water of salvation."
