Garnier, Jean a French Jesuit, was born at Paris in 1612. He joined the order in 1628, and soon displayed great talent and aptness for study and teaching. As usual, this gift was fostered by the society, and for forty years Garnier held different professorships of theology and literature. He died at Bologna, on his way to Rome, October 16, 1681. His most important works are on the Pelagian controversy, his editions of Juliani Eclan. episcopi libellus, notis illust. (1668), and also of Marii Mercatoris opera cum notis, etc. (1673, fol.). The dissertations appended to this edition are still valuable to the history of Pelagianism. In 1675 he published the Breviarium sive historia controversiarum Nestoriance et Eutychiance of the archdeacon Liberatus. After his death, father Hardouin published his Supplement to the Works of Theodoretus, at the beginning of which he gives a eulogy of Garnier's labors and talents. — Feller, Dict.
