He was converted to Methodism in 1800 and worked for eight years as an itinerant preacher in the wilderness of the Canadian provinces, serving communities in the areas of Kingston, York, London, Niagara, and Montreal.

Although his career was an illustrious one,[citation needed] Bangs's reputation suffered badly when he failed to support Methodist abolitionists at the General Conference of 1844.
