A preacher to the king who was struck off the list of royal preachers in 1788 for the political tone of a sermon, Fauchet sat on the electors’ committee at the Hôtel de Ville on 14 July 1789 and pronounced the funeral oration for those killed at the Bastille. In 1790 he founded the Cercle Social with Nicolas de Bonneville and wrote in its journal, the Bouche de fer, arguing for a Christianity of real social equality. He took the oath to the Civil Constitution of the Clergy and was elected constitutional bishop of the Calvados, then deputy for that department to the Legislative Assembly and the Convention, where he sat with the Gironde. Arrested in July 1793 and accused of complicity with Charlotte Corday, an allegation she herself denied, he was condemned with the Girondins and guillotined on 31 October 1793.
