Most scholars today agree that Rabelais wrote from a perspective of Christian humanism. This has not always been the case. Abel Lefranc, in his 1922 introduction to "Pantagruel", depicted Rabelais as a militant anti-Christian atheist. On the contrary, M. A. Screech, like Lucien Febvre before him, describes Rabelais as an Erasmian. While formally a Roman Catholic, Rabelais was an adherent of Renaissance humanism, which meant that he favoured classical Antiquity over the "barbarous" Middle Ages and believed in the need of reform to bring science and arts to their classical flourishing and theology and the Church to their original Evangelical form as expressed in the Gospels. In particular, he was critical of monasticism. Rabelais criticised what he considered to be inauthentic Christian positions by both Catholics and Protestants, and was attacked and portrayed as a threat to religion or even an atheist by both. For example, "at the request of Catholic theologians, all four Pantagrueline chronicles were censured by either the Sorbonne, Parliament, or both". On the opposite end of the spectrum, John Calvin saw Rabelais as a representative of the numerous moderate evangelical humanists who, while "critical of contemporary Catholic institutions, doctrines, and conduct", did not go far enough; in addition, Calvin considered Rabelais' apparent mocking tone to be especially dangerous, since it could be easily misinterpreted as a rejection of the sacred truths themselves.
