  • Cornelis Jansenius


Bishop of Ypres, Belgium, and founder of Jansenism. Educated at Utrecht and Louvain, he commenced c.1604 his friendship with Jean du Verger de Hauranne, with whom he pursued ecclesiastical studies for about 12 years. In 1617 he was appointed president of the College de Sainte-Pulchérie, Louvain, and in 1619 received the degree of Doctor of Theology and later a chair of exegesis. During this time he wrote several exegetical and polemical works, all perfectly orthodox in doctrine, and in 1636 he was consecrated Bishop of Ypres. For years he had been occupied with a work, originating in his intercourse with du Verger, on Saint Augustine‘s doctrine of grace, which was not published until after his death. In 1641 the Augustinus, as it was called, was prohibited by the Holy See, and its five heretical propositions concerning grace were solemnly condemned in 1653. Though Jansen’s name was attached to the heresy which arose after the circulation of his book, he was not a heretic but lived and died in the bosom of the Church. The original edition of the Augustinus contains a statement of his undying loyalty and submission to the Church.
