H. G. Wells, in his book "Crux Ansata: An Indictment of the Roman Catholic Church," presents a critical perspective on the Roman Catholic Church, characterizing it as a profoundly negative force in the world. Wells argues that the institution has a history of corruption and moral failure, leading to significant societal harm over the centuries.

The assertion that the Roman Catholic Church is the "most evil institution in the world" reflects Wells' belief that its practices and doctrines contribute to widespread injustice and suffering. His work serves as a strong condemnation of the Church, urging readers to examine its impacts on society critically.
