These disputes occasioned such disturbance in Rome, that the whole affair was taken notice of by the inquisition. Molinos and his book, and father Petrucci, with his treatises and letters, were brought under a severe examination; and the Jesuits were considered as the accusers. One of the society had, indeed, approved of Molinos' book but the rest took care he should not be again seen at Rome. In the course of the examination both Molinos and Petrucci acquitted themselves so well, that their books were again approved, and the answers which the Jesuits had written were censured as scandalous.
Petrucci's conduct on this occasion was so highly approved, that it not only raised the credit of the cause, but his own emolument; for he was soon after made bishop of Jesis, which was a new declaration made by the pope in their favour. Their books were now esteemed more than ever, their method was more followed, and the novelty of it, with the new approbation given after so vigorous an accusation by the Jesuits, all contributed to raise the credit, and increase the number of the party.
The behaviour of father Petrucci in his new dignity greatly contributed to increase his reputation, so that his enemies were unwilling to give him any further disturbance; and, indeed, there was less occasion given for censure by his writings than those of Molinos. Some passages in the latter were not so cautiously expressed, but there was room to make exceptions to them; while, on the other hand, Petrucci so fully explained himself, as easily to remove the objections made to some parts of his letter.
The great reputation acquired by Molinos and Petrucci, occasioned a daily increase of the Quietists. All who were thought sincerely devout, or at least affected the reputation of it, were reckoned among the number. If these persons were observed to become more strict in their lives and mental devotions, yet there appeared less zeal in their whole deportment as to the exterior parts of the church ceremonies. They were not so assiduous at mass, nor so earnest to procure masses to be said for their friends; nor were they so frequently either at confession, or in processions.
Though the new approbation given to Molinos' book by the inquisition had checked the proceedings of his enemies; yet they were still inveterate against him in their hearts, and determined if possible to ruin him. They insinuated that he had ill designs, and was, in his heart, an enemy to the Christian religion: that under pretence of raising men to a sublime strain of devotion, he intended to erase from their minds a sense of the mysteries of christianity. And because he was a Spaniard, they gave out that he was descended from a Jewish or Mahometan race, and that he might carry in his blood, or in his first education, some seeds of those religions which he had since cultivated with no less art than zeal. This last calumny gained but little credit at Rome, though it was said an order was sent to examine the registers of the place where Molinos was baptised.
