Explanation: Hi, Walter Rauschenbusch, was a clergyman and theology professor who led the Social Gospel movement in the United States.
With the publication of “Christianity and the Social Crisis” in 1907, Rauschenbusch gained recognition as the leading voice of the Social Gospel movement in the United States. Considered both dynamic and compassionate, he always regarded himself as an evangelist seeking to win men to a “new birth” in Christ. At the same time, he believed that the Kingdom of God required social as well as individual salvation, and he demanded “a new order that would rest on the Christian principles of equal rights and democratic distribution of economic power.”
