Unigenitus

Unigenitus (named for its Latin opening words Unigenitus Dei Filius, or "Only-begotten Son of God") is an apostolic constitution in the form of a papal bull promulgated by Pope Clement XI in 1713.

It contained the four Gospels in French, with short explanatory notes, serving as aids for meditation. The work was approved by the Bishop of Châlons-sur-Marne. Enlarged editions followed, containing an annotated French text of the complete New Testament, in 1678 and 1693–1694. This last edition was highly recommended by the new Bishop of Châlons, Louis Antoine de Noailles. While the first edition of the work contained only a few Jansenist points, its tendency became more apparent in the second edition, and in its complete form, as it appeared in 1693, it was – in the words of the 1912 Catholic Encyclopedia – "pervaded with practically all the errors of Jansenism".
