Prior to this, Pope Pius IX had written a document called the "Syllabus of Errors. "The Syllabus was made up of phrases and paraphrases from earlier papal documents, along with index references to them, and presented as a list of "condemned propositions". It does not explain why each particular proposition is wrong, but it cites earlier documents to which the reader can refer for the Pope's reasons for saying each proposition is false. Among the statements included in the Syllabus are: "is an error to say that Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true" (15); "is an error to say that In the present day it is no longer expedient that the Catholic religion should be held as the only religion of the State, to the exclusion of all other forms of worship"; "is an error to say that Hence it has been wisely decided by law, in some Catholic countries, that persons coming to reside therein shall enjoy the public exercise of their own peculiar worship".
