Isidore Mullois

Isidore Mullois was a French Catholic priest and author born on December 7, 1811, in Saint-Rémy, Calvados, and he died in Paris on January 5, 1870. Bibliographic records identify him as Jacques-Isidore Mullois and note that he served first in the Diocese of Bayeux from 1837 to 1851, then in the Diocese of Paris.

His career later brought him close to the imperial court: the Bibliothèque nationale de France records that he became first chaplain of the emperor's household in 1853, was also an honorary canon of Saint-Denis, and was named a Chevalier of the Légion d'honneur in 1861.

Mullois is known today mainly through religious works such as Cours d'éloquence sacrée populaire and The Clergy and the Pulpit in Their Relations to the People. Those books present preaching as something more than polished rhetoric: for him, it depended on understanding ordinary people and speaking to them with compassion, simplicity, and moral seriousness.
