Dear readers, Catholic Online was de-platformed by Shopify for our pro-life beliefs. They shut down our Catholic Online, Catholic Online School, Prayer Candles, and Catholic Online Learning Resources essential faith tools serving over 1.4 million students and millions of families worldwide. Our founders, now in their 70's, just gave their entire life savings to protect this mission. But fewer than 2% of readers donate. If everyone gave just $5, the cost of a coffee, we could rebuild stronger and keep Catholic education free for all. Stand with us in faith. Thank you.Help Now >
Louis Thomassin
FREE Catholic Classes
Theologian and French Oratorian, b. at Aix-en-Provence 28 Aug., 1619; d. in Paris, 24 Dec., 1695. At the age of thirteen he entered the Oratory and for some years was professor of literature in various colleges of the congregation, of theology at Saumur, and finally in the seminary of Saint Magloire, in Paris, where he remained until his death. His chief works are: "Ancienne et nouvelle discipline de l'église touchant les bénéfices et les bénéficiers" 93 vols. in fol., Paris, 1678-79), which passed through several French and Latin editions and several abridgments; "Dogmatum theologicorum . . . de Incarnatione, de Dei proprietatibus . . . etc." (3 vols. in fol., Paris, 1680-89), likewise re-edited several times (the treatise on the Incarnation is regarded as Thomassin's masterpiece); a series of "Traités historiques et dogmatiques" on ecclesiastical fasts, feasts, the Divine Office, the unity of the Church, truth and lying, alms, business and usury (1680-97), a series of methods of studying and teaching the humanities, philosophy, grammar, history (1681-92); the "Glossarium universale hebraicum" (in fol., Paris, 1697); "Traité dogmatique et historique des édits et d'autres moyens. . . dont on s'est servi . . . pour établir et maintenir l'unité de l'église" (3 vols., in 4°, Paris, 1705). The last-named two posthumous works were published by P. Bordes, who wrote a life of Thomassin at the beginning of the "Glossarium". Thomassin was one of the most learned men of his time, "Vir stupendae plane eruditionis", as Hurter says, in his "Nomenclator", II (Innsbruck, 1893), 410.
