BAILLY, LOUIS. - Theologian, b. in France, near Beaune, in 1730, d. in 1808. He was a canon of Dijon and professor of dogmatic theology in the seminary until the Revolution. Afterwards he moved to Switzerland, where he devoted himself to his studies. Having returned to his homeland, he refused every dignity in order to devote himself solely to the service of the great hospice of Beaune.
The following works are known by him: Theologia dogmatica et moralis (8 vols., 3rd ed., Dijon 1810), a work of value, used for decades as a school manual in various seminaries of France, but which incurred the condemnation of the Index in 1852 «donec corrigatur», because of the excessive rigorism professed by the author; Tractatus de vera religione (6th ed., ibid. 1758), Tractatus de Ecclesia (2 vols., ibid. 1780), in which the principles of the Gallican declaration of 1682, drawn up by Bossuet and known as the Gallican Articles, are defended; I principi della fede cattolica, a work composed during his stay in Switzerland.
