Louis Bourdaloue (20 August 1632 – 13 May 1704) was a French Jesuit and preacher.
Biography
Louis Bourdaloue was born in Bourges where his father practiced law. He began his studies at the Jesuit Collège de Sainte-Marie in Bourges. In November 1648 he entered the Society of Jesus, and was appointed successively professor of rhetoric, philosophy and moral theology, in various Jesuit colleges. His success as a preacher in the provinces led his superiors to call him to Paris in 1669 to occupy for a year the pulpit of the church of St. Louis.
He preached at the court of Versailles during the Advent of 1670 and the Lent of 1672, and was subsequently called again to deliver the Lenten course of sermons in 1674, 1675, 1680 and 1682, and the Advent sermons of 1684, 1689 and 1693. This was all the more noteworthy as it was the custom never to call the same preacher more than three times to court.
Places were secured at daybreak; princes and prelates crowded to hear him, and on one memorable occasion, several of the most distinguished members of the hierarchy, among them Bossuet himself, withdrew in anger because the seats they claimed were not granted. Bossuet himself, however, remained in a gallery apart to listen to the discourse.
Bourdaloue generally addressed issues of morality in daily life and his experience as a confessor gave him insight into people wrestling with ethical issues. Many of his sermons were adopted as textbooks in schools.
