Regalism and Jansenism were traditional enemies of the Vatican in its government of the Church. Using these two as instruments, the party of Voltaire and the educated and anti-Christian Encyclopedists were rising in power at the time. They planned for nothing less that the destruction of the Church, and felt the first step was to crush the Jesuits. They persuaded monarchs that the Jesuits were an obstacle to Regalism, and thus a danger to themselves, their rule, their realms. This situation faced Clement from the moment he took the crown.
He was called the saint (by his people), and was an exemplary man who, notwithstanding the immense revenues of his diocese and his private estate, was always without money owing to the lavishness of his alms-deeds, and would give away even his linen.
