In A Theology for the Social Gospel, Walter Rauschenbusch sets out a theological basis for the Social Gospel movement. He explores how key Christian doctrines apply in the Social Gospel, including sin and redemption, the atonement, the Holy Spirit, eschatology, and the Kingdom of God. Rauschenbusch argues that all society must be brought “under the law of Christ” and that the church should be a significant social factor.
Walter Rauschenbusch (1861–1918) was a Baptist pastor and important figure in the Social Gospel movement. He co-founded The Brotherhood of the Kingdom, a group of thinkers advocating social change. His writings influenced Martin Luther King Jr., Desmond Tutu, and multiple social justice ministries.
