The Papal Syllabus of Errors. A.D. 1864.

IV. SYLLABUS ERRORUM.

[This document, though issued by the sole authority of Pope Pius IX., Dec. 8,1864, must be regarded now as infallible and irreformable, even without the formal sanction of the Vatican Council. It is purely negative, but indirectly it teaches and enjoins the very opposite of what it condemns as error. See Vol. I. § 20, pp. 128–134.]
