Charles de La Rue (3 August 1643 – 27 May 1725), known in Latin as Carolus Ruaeus, was one of the great orators of the Society of Jesus in France in the seventeenth century
He entered the novitiate on 7 September 1659, and being afterwards professor of the humanities and rhetoric, he attracted attention while still young by a poem on the victories of Louis XIV. Pierre Corneille translated it and offered it to the king, saying that his work did not equal the original of the young Jesuit. He wrote several tragedies, published an edition of Virgil, and wrote several Latin poems. After having several times refused to permit him to go to Canada, his superiors assigned him to preaching; as an orator he was much admired by the court and the king. His funeral orations on the Dukes of Burgundy and Luxemburg, and that on Jacques-Bénigne Bossuet, his sermons on "Les Calamités publiques" and "The Dying Sinner" have been regarded as masterpieces by the greatest masters. He preached missions among the Protestants of Languedoc for three years. He was a most virtuous religious, and during his last years endured courageously great infirmities.
