Cult of the Supreme Being
Robespierre's desire for revolutionary change was not limited only to the political realm. He also opposed the Catholic Church and the pope, particularly their policy of clerical celibacy. Having denounced the Cult of Reason and other perceived excesses of dechristianization undertaken by political opponents, he sought to instill a spiritual resurgence across the nation based on Deist beliefs. On 6 May 1794 Robespierre announced to the Convention that in the name of the French people, the Committee of Public Safety had decided to recognize the existence of God and the immortality of the human soul. Accordingly, on 7 May, Robespierre delivered a long presentation to the Convention ‘on the relation of religious and moral ideas to republican principles, and on national festivals’. He dedicated festivals to the Supreme Being, to Truth, Justice, Modesty, Friendship, Frugality, Fidelity, Immortality, Misfortune, etc.  The Cult of the Supreme Being was based on the creed of the Savoy chaplain that Jean-Jacques Rousseau had outlined in Book IV of Emile.
In the afternoon of 8 June (also the Christian holiday of Pentecost) a "Festival of the Supreme Being" was held. Everything was arranged to the exact specifications that had been drawn up previously set before the ceremony. The guillotine had been moved to the original standing place of the Bastille. Pregnant women and breastfeeding mothers with their babies were specifically invited to walk in the procession which started at the Tuileries. (Joachim Vilate had invited Robespierre to have lunch in the Pavillon de Flore, but he ate little.)
The festival was also Robespierre's first appearance in the public eye as a leader for the people, and also as president of the Convention, to which he had been elected four days earlier. Witnesses state that throughout the "Festival of the Supreme Being", Robespierre beamed with joy. He was able to speak of the things about which he was passionate, including virtue, nature, deist beliefs and his disagreements with atheism. He wore feathers on his hat and held fruit and flowers in his hands, and walked first in the festival procession. According to Michelet: "Robespierre, as usual, walked quickly, with an agitated air. The Convention did not move nearly so fast. The leaders, perhaps maliciously and out of perfidious deference, remained well behind him, thereby isolating him." The procession ended on the Champ de Mars. The Convention climbed to the summit, where a liberty tree had been planted. Robespierre delivered two speeches in which he emphasized his concept of a Supreme Being: there would be no Christ, no Mohammed.Someone was heard saying, "Look at the blackguard; it's not enough for him to be master, he has to be God". On 15 June, the president of the Committee of General Security, Vadier, on behalf of the two committees presented a report on a new conspiracy by Catherine Théot, Christophe Antoine Gerle and three others. He insinuated that Robespierre fitted her prophecies. His speech caused much laughter in the convention.  Robespierre felt ridiculed and demanded on the 26th that the investigation of Théot be stopped and Fouquier-Tinville replaced.  The deist Cult of the Supreme Being that he had founded and zealously promoted generated suspicion in the eyes of both anticlericals and other political factions, who felt he was developing grandiose delusions about his place in French society.
