Thus, as it was a matter rather of religion than of jurisprudence, they resolved to begin by prayer to God, who is the Father of all Light, rightly considering that all France was watching the trial with eager eyes, that it was shrouded in a thick veil of obscurity, and that their verdict would entail important consequences. They therefore prepared to receive divine assistance and grace by frequent confessions, and by often receiving the Holy Sacrament. Then they decreed a general procession to implore celestial aid in so difficult a matter; and, to excite the devotion of the masses by their example, they went in a body, during the whole of the trial, to visit the Churches of the city, set aside by the Bishop for forty hour services, and reached each in time for the elevation of the host. Thence the Exorcists went to the Church fixed upon for the Exorcisms, and the judges proceeded to the tribunal to continue the case; in the evening all returned to church for evensong. The examination lasted forty days, during which Demons gave them the clearest proofs of their presence in the bodies of the persons exorcised, and every day added new evidence against Grandier, and yet never said anything against him which did not turn out strictly true. These assertions merit distinct proof, which will be found interesting. As regards the presence of Devils in the possessed, the Church teaches us in its ritual, that there are four principal signs, by which it can be undoubtedly recognised. These signs are the speaking or understanding of a language unknown to the person possessed; the revelation of the future, or of events happening far away; the exhibition of strength beyond the years and nature of the actor; and floating in the air for a few moments. The Church does not require, in order to have recourse to Exorcisms, that all these marks should be found in the same subject; one alone, if well authenticated, is sufficient to demand public exorcism. Now, they are all to be found in the Nuns of Loudun, and in such numbers that we can only mention the principal cases. Acquaintance with unknown tongues first showed itself in the Mother-Superior. At the beginning, she answered in Latin the questions of the Ritual proposed to her in that language. Later, she and the others answered in any language they thought proper to question in. M. de Launay de Razilli, who had lived in America, attested that, during a visit to Loudun, he had spoken to them in the language of a certain savage tribe of that country, and that they had answered quite correctly, and had revealed to him events that had taken place there. Some gentlemen of Normandy certified in writing that they had questioned Sister Clara de Sazilli in Turkish, Spanish, and Italian, and that her answers were correct. M. de Nismes, Doctor of the Sorbonne, and one of the chaplains of the Cardinal de Lyon, having questioned them in Greek and German, was satisfied with their replies in both languages.
