Strange as it may appear, it was the protection accorded the theatre, and the extreme indulgence shown to all connected with it, by a great party in the Church itself that was directly responsible for the termination of this happy state of affairs and the violent reaction, of which the conduct of Harlay de Chanvalon and the curé of Saint-Eustache towards Molière was but the beginning. For some time, the Jesuits seem to have regarded the theatre with disfavour; but towards the middle of the seventeenth century, perceiving that it might very readily be made to serve as a vehicle for the propagation of their own ideas, their attitude changed, and they not only permitted all who came under their influence to attend the play, but even encouraged the pupils in their colleges to perform theological comedies, in which their enemies, the Jansenists, were held up to ridicule. This, naturally, had the effect of exasperating the zealots of Port-Royal and their numerous adherents, who, always hostile to the drama, quickly became bitterly antagonistic and required but very slight provocation to declare open war. This provocation was not long in coming. In 1665, the clever but eccentric playwright Desmarets de Saint-Sorlin, the author of _Les Visionnaires_, having passed "_à la devotion la plus outrée_," espoused the cause of the Jesuits, and, believing that he had received a call from Heaven to combat the heretics--that is to say, the Jansenists--made a violent attack upon them. The Jansenists replied by the pen of their famous publicist, Nicole, who stigmatized those who wrote for the theatre as "public poisoners, not of bodies, but of souls." Racine, believing his honour touched, joined in the fray and ridiculed the bigotry of Port-Royal. Nicole rejoined with a _Traité de la Comédie_, wherein, relying on the teaching of the Fathers of the Church, he condemned not only dramatic authors, but those who interpreted them. "The playhouse," said he, "is a school of Vice. The profession of an actor is an employment unworthy of a Christian," and much more to the same effect. Armand de Bourbon, Prince de Conti, formerly a generous patron of the drama and of Molière, but now, for some time past, a Jansenist of the most advanced type, published a similar work, and gave it as his opinion that a troupe of actors was "a troupe of devils," and to amuse oneself at the play was to "delight the demon." So the war went on.
