Cousin says that the whole literature of maxims and reflections issued directly from the salon of a kind and good woman who had retired to a convent with no other desire than to live over her life, to recall her past and what she had seen and felt therein; and upon her society, that woman impressed her own tastes, elegance, and seriousness. Her great act of benevolence was her protection of Port-Royal. When, after the death in 1661 of Mother Angélique Arnauld, that institution became the object of persecution and its tenants were either imprisoned or compelled to seek refuge in the various families of Paris, Mme. de Sablé remained faithful to its principles; she lived with her friends, Mme. de Longueville and Mme. de Montausier, until 1669, when, with the coöperation of Mme. de Longueville, who exerted all her influence for Port-Royal, she finally succeeded in bringing about its reopening. At least, Cousin ascribes this result to Mme. de Sablé, but he may have somewhat exaggerated her influence in this respect. From her retreat at Port-Royal, she kept up a constant correspondence with her friends all over France; she lived there until 1678, with but one intimate friend, Mme. de Longueville.

Mme. de Sablé had remarkable gifts; her mission in politics, religion, and literature seems to have been to excite to action, to stimulate and to bring out to its fullest value, the talents and genius of others. In her modest salon, she inspired the great and illustrious work which will keep her memory alive as long as the Maxims and Pensées are read. Her name will be connected with that of Mme. de Longueville, because of their ideal friendship, and with that of Port-Royal because of her ardent and self-sacrificing support of it in the time of its direst persecution, when any exhibition of sympathy was dangerous in the extreme; and finally, her name will always be connected with that small circle of French society of the seventeenth century, which was noble, moral, and elevating to an unusual degree.

Somewhat later in the century a different movement was started by a woman, which involved many of the highest in rank at court. This took the form of a kind of mystical enthusiasm, running into a theory of pure love, and was instigated by Mme. Guyon, a widow, still young, and gifted with a lofty and subtile mind. After losing her husband, whom she had converted to her religious views, she went, in 1680, to Paris to educate her children. Becoming interested in religion, she went to Geneva, where she became very intimate with a priest who was her spiritual director, and whom she soon wholly subjected to her influence. On account of their views on sanctification, they were ordered to leave.

After travelling over Europe for a number of years, and writing several works, including Spiritual Torrents and Short and Easy Method of Making Orison with the Heart, the widow returned to Paris, with the intention of living in retirement; but so many persons of all ranks sought her out, that she organized, for ladies of rank, meetings for purposes of prayer and religious conversation. The Duchess of Beauvilliers, the Duchess of Béthune, the Countess of Guiche, the Countess of Chevreuse, and many others, with their husbands, became her devoted adherents.

According to Mme. Guyon, prayer should lose the character of supplication, and become simply the silence of a soul absorbed in God. "Why are not simple folks so taught? Shepherds, keeping their flocks, would have the spirit of the old anchorites; and laborers, whilst driving the plow, would talk happily with God. In a little while, vice would be banished and the kingdom of God would be realized on earth." Thus, her doctrine was directly opposite to the theories of the Jansenists.

At that time, 1687 to 1688, all religious movements, however quiet, were condemned at Rome; and the teachings of Mme. Guyon were found to differ very little from those of the Spanish priest Molinas. The first arrest, that of her friend Lacombe, was soon followed by that of Mme. Guyon herself, by royal order; she was released through the intercession of Mme. de Maintenon, who was fascinated by her to the extent of permitting her to teach her doctrines at Saint-Cyr, Upon the appearance of her Method of Prayer, an examination was instituted by Bossuet and Fénelon, who marked out a few passages as erroneous—a procedure to which she submitted. However, Bossuet himself wrote a treatise against her Method of Prayer, in which he cast reflections upon her character and conduct; to that work Fénelon refused to subscribe, which antagonistic proceeding brought on the great quarrel between those two absolute ecclesiasts. In fact, Fénelon became imbued with the doctrines of Mme. Guyon.

She was imprisoned at various times; and when a letter was received from Lacombe, who had been imprisoned at Vincennes for a long time, exhorting her to repent of their criminal intimacy, Mme. Guyon's cause was hopeless. She was sent to the Bastille, her son was dismissed from the army, and many of her friends were banished. In 1702 she was released from prison and banished to Diziers; she passed the remainder of her life in complete retirement at Blois.

Fénelon had written a treatise, Maxims of the Saints, which was said to favor Mme. Guyon's doctrines, and which was sent to Rome for examination. He defined her doctrine of divine love in the following maxim, which was condemned at Rome:

"There is an habitual state of love of God, which is pure charity without any taint of the motive of self-interest. Neither fear of punishment nor desire of reward has, any longer, part in this love; God is loved, not for the merit, but for the happiness to be found in loving Him."
