The manuscript is an autograph letter written in the hand of Du Buit and introducing Du st esprit, penned by the author’s father. The author reflects on different religious dogmas and the general principles characterising Catholicism, Protestantism, and animism (indigenous religions), advocates for the need to strip religion of Theological absurdities and argues for the Holy Spirit’s superiority over God. Additionally, Du st esprit accompanies the manuscript (iii.312–326).
