Jean-Baptiste Languet de Gergy (1674–1750) was parish priest at Eglise Saint-Sulpice in Paris from 1714 to 1748.
[1] A staunch moralist, Languet is famous for denying the sacraments to Marie Louise Élisabeth d'Orléans, Duchess of Berry, eldest daughter of Philippe II, Duke of Orléans.
[3] At the end of March 1719, the young widow became critically "ill", shut up in a little chamber of her Luxembourg Palace.
In fact, she was deep in the pangs of childbirth and as she seemed close to dying, Languet was called upon to administer her the sacraments.
At last, the Duchess was delivered, ending the crisis but not the scandal provoked by Languet's refusal to turn a blind eye to her clandestine childbearing.
