Scholars have called him a saintly pope because he reformed abuses by the Church, including simony, nepotism and the lavish papal expenditures that had caused him to inherit a papal debt of 50,000,000 scudi. By eliminating certain honorary posts and introducing new fiscal policies, Innocent XI was able to regain control of the church's finances.[1] Innocent X and Clement XI battled Jansenism and Gallicanism, which supported Conciliarism, and rejected papal primacy, demanding special concessions for the Church in France. This weakened the Church's ability to respond to gallicanist thinkers such as Denis Diderot, who challenged fundamental doctrines of the Church.[168]
