The landmark text by William Carey sets out the principles of converting natives of foreign lands to Christianity. An Enquiry into the Obligations of Christians to Use Means for the Conversion of the Heathens led directly to the formation of the Baptist Missionary Society, and was to inspire Christian missionaries for generations to follow. The author himself could boast great experience: having amassed oratorical experience during his younger years as a schoolmaster, and as the pastor of Leicester's Harvey Lane Baptist Church. The text contains impassioned arguments which attempt to justify missionary work, followed by a researched history of the practice. Later, Carey discusses charts which measure populations through the world and their religious beliefs. All of these charts are reproduced for this edition, allowing the reader insight into Carey's ambitious approach.
