Charles Monroe Sheldon (February 26, 1857 – February 24, 1946) was an American minister in the Congregational churches and leader of the Social Gospel movement. His novel, In His Steps, introduced the principle of "What Would Jesus Do?" which articulated an approach to Christian theology that became popular at the turn of the 20th Century and had a revival almost one hundred years later. The stretch of US-24 on the north side of Topeka, Kansas between US-75 and K-4 is named the Charles Sheldon Memorial Highway in his honor.
Sheldon was a graduate of Phillips Academy, Andover (Class of 1879). He became an advocate of the late nineteenth century school of thought known as Christian Socialism. His theological outlook focused on the practicalities of the moral life, with much less emphasis on the doctrinal traditions of personal redemption from sin in Christ. In the winter of 1896 Sheldon developed a sermon story that he read as a weekly series from the pulpit of Central Congregational Church in Topeka, Kansas. The unifying theme of these sermons was based on posing the question, "what would Jesus do?" when facing moral decisions. He viewed this question as traditional within Christianity and likely drew some inspiration from William T. Stead's If Christ came to Chicago! (1893) and other earlier sources.
