Nicolas-Antoine Boulanger wrote a contentious book titled Christianity Unveiled in the late 18th century. In addressing many of the core assumptions held by Christians at the time, the book offers a critical study of the tenets and outcomes of the Christian religion. According to Boulanger, Christianity's doctrines are frequently incoherent and illogical and are founded on myths and superstitions. He contends that the idea of redemption through faith alone is hazardous because it encourages complacency and dissuades moral responsibility. He also disputes the veracity of miracles and the concept of original sin. The book also explores the political and historical ramifications of Christianity, making the case that it has always been exploited as a justification for oppression and bloodshed. In his analysis of the Church's function in society, Boulanger casts doubt on its legitimacy and inclination to prioritize its own interests above those of the populace.
