The real struggle regarding /Augustinus/ was to be waged, however, in Paris and France. There, the Abbot of St. Cyran had been busily at work preparing the way for Jansen's doctrine, by attacking the modern laxity of the Church, and advocating the necessity of a complete return to the rigorous discipline of the early centuries. He had made the acquaintance of the family of the celebrated lawyer, Antoine Arnauld, six of whose family had entered the convent of Port Royal, of which one of them, Angelique,[2] was then superioress, while his youngest son, Antoine, a pupil of St. Cyran, was destined to be the leader of the French Jansenists. St. Cyran insisted on such rigorous conditions for the worthy reception of the Eucharist, that people feared to receive Holy Communion lest they should be guilty of sacrilege, and for a similar reason many priests abstained from the celebration of Mass. He attacked the Jesuits for their laxity of doctrine and practice in regard to the Sacrament of Penance. He himself insisted on the absolute necessity of perfect contrition and complete satisfaction as an essential condition for absolution. These views were accepted by the nuns at Port Royal and by many clergy in Paris. On account of certain writings likely to lead to religious trouble St. Cyran was arrested by order of Cardinal Richelieu (1638) and died in 1643. His place was taken by his brilliant pupil, Antoine Arnauld, who had been ordained priest in 1641, and who like his master was the determined opponent of the Jesuits. In 1643 he published a book entitled /De la frequente Communion/, in which he put forward such strict theories about the conditions required for the worthy reception of the Eucharist that many people were frightened into abstaining even from fulfilling their Easter Communion. Despite the efforts of St. Vincent de Paul and others the book was read freely and produced widespread and alarming results.
