Isaac Habert

Habert, Isaac, was a native of Paris, where he became Doctor of the Sorbonne, Canon and Lecturer in Divinity to the Chapter of the Cathedral, and Preacher to the King. On Dec. 17, 1645, he was consecrated Bp. of Vabres (Aveyron), a post which he held with esteem for over twenty years. He died of apoplexy while on a visit to Pont-de-Salars, near Rodez, Sept. 15, 1668, and was buried in the Cathedral at Vabres.
He is best known as a writer against Jansenism; and as the editor of the Liber Pontificalia, Paris, 1643, which contains the Greek service with a Latin version by himself. He contributed a number of Latin hymns to the Paris Breviary of 1643. Those which are repeated in the Paris Breviary of 1736 are marked there H. Vabr. Ep., or Hab. Vabr. Ep. [Rev. James Mearns, M.A.]
