Longinqua §19

¹⁹ We have Ourselves, on frequent occasions, laid down many rules respecting the duties of a good writer; many of which were unanimously inculcated as well by the Third Council of Baltimore as by the archbishops in their meeting at Chicago in the year 1893. Let Catholic writers, therefore, bear impressed on their minds Our teachings on this point as well as yours; and let them resolve that their entire method of writing shall be thereby guided, if they indeed desire, as they ought to desire, to discharge their duty well.
