a French Oratorian, was born near Bologne-sur-Mer in 1636. Professor of theology for fifty years at the school founded at Sarumur by the Oratorians, he was one of the most active adversaries of the Jansenists, and published against them Les Sentiments de Stiuint Agustine sur la Grace (Lyons, 1682. 1700, 4to). Although he abstains from all personalities, his adversaries spoke of it with the utmost contempt. Abb Goujet acknowledges Porcq's piety, and says that he always carefully avoided anything that was akin to sectarianism, but that he wrote against Jansenism because he considered it wrong. He wrote as a true polemic against doctrines, and not persons. See Dupin, Bibl. des Aut. Eccles. du 18ieme Siecle, 2, 385.
