The book is a warning against the dangers of joining the Freemasons, a secret society that was gaining popularity at the time. Southwick argues that Freemasonry is a corrupt and immoral organization that goes against Christian values and promotes anti-democratic principles. He encourages young men to stay away from the society and instead focus on their personal and spiritual growth. The book provides a detailed history of Freemasonry, its rituals, and its influence on society. It also includes testimonies from former members who have renounced the society and its practices. A Solemn Warning Against Free Masonry is a passionate plea to young men to resist the allure of secret societies and uphold their moral values.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
