For, while he wrote much, he published little. In fact, he never wrote directly for publication in general. Yet we have a plethora of autographic manuscripts produced under his direction, manuscripts copied by early Marianists, and manuscript notes taken by those who heard his instructions,discussions, and sermons. With a few exceptions, the documents containing his Marian doctrine remained unpublished for many years. In the last half-century a number of definitive editions, translations, syntheses, and analytical studies have appeared in published form.
More writings await editing and publication.
The Petit Traite de la Connaissance de Marie saw publication in 1927 by Tequi of Paris. The Petit Traite was actually composed by Father Jean-Baptiste Fontaine, one of the Founder's most faithful disciples, in accord with Chaminade's ideas and often using expressions furnished by him. It contains the authentic Marian theology of Father Chaminade because he approved and published it. The Petit Traite appeared in English as Our Knowledge of Mary in 1938, published-by Bruce of Milwaukee.
