Louis-Antoine de Noailles (27 May 16514 May 1729), second son of Anne, 1st duc de Noailles, was a French bishop and cardinal. His signing of the Unigenitus bull in 1728 would end the formal Jansenist controversy. Biography Louis-Antoine de Noailles was born at the Château of Teyssiére in Auvergne, France, on 27 May 1651 to Anne, 1st duc de Noailles and captain- general of Roussillon, and his wife, Louise Boyer, a former lady-in-waiting to Queen Anne of Austria. Noailles received his doctorate in theology from the Sorbonne on 14 March 1676. He was appointed bishop of Cahors in March 1679 but served only briefly before Pope Innocent XI ordered him transferred in 1680 to head the diocese of Châlons-sur-Marne, which made him a peer of France. On 19 August 1695, in recognition of Noailles's family connections, King Louis XIV made him archbishop of Paris and Duke of Saint-Cloud, and in 1700 Pope Innocent XII made him a cardinal. According to Antoine Degert, writing in the Catholic Encyclopedia, although Noailles was not brilliant, "he was possessed of piety, zeal, and activity." He is noted for having raised money to feed famine victims by selling his silver tableware in 1709, and for having spent a considerable part of his inheritance on redecorating Notre Dame. Noailles was a friend of François Fénelon, with whom he had studied at the Collège du Plessis before entering the Sorbonne. Nonetheless, he was among the bishops who condemned Fénelon's Maximes des Saints, ending the theologian's career. Noailles came to know the controversial young Lutheran Count Nicholas Ludwig von Zinzendorf in 1719 during the young man's Grand Tour. The two found great spiritual connection despite their historic denominational differences. They maintained a relationship and correspondence the rest of Noailles' life; and Noailles became a member of Zinzendorf's Order of the Grain of Mustard Seed, a secret society where nobles and church leaders committed to work together to build the spiritual Kingdom of God. The Cardinal also served as Godfather to Zinzendorf's son Christian Renatus (1727–1756). Noailles acted as a staunch moralist when at the end of March 1719 he firmly stood behind the curé of Saint-Sulpice. who refused to administer the sacraments to the Regent's daughter, Louise Élisabeth, Duchess of Berry, who was in a critical condition giving birth to an illegitimate child in the Palais de Luxembourg.
