Pope Leo XIII's 1884 encyclical Humanum Genus is the Church's most comprehensive explanation of why, ever since 1738, she has forbidden Catholics to become Freemasons. Reading the encyclical today, one has the thought that its continued relevance has less to do with the present-day activities of Masonic organizations, and more to do with the fact that Masonic ideas have already come to pervade Western society.
