Walter Rauschenbusch was an American Baptist theologian and pastor who became a central figure in the Social Gospel movement. Born in 1861 in Rochester, New York, he served as a minister in New York City's Hell's Kitchen before teaching at the Rochester Theological Seminary. He is primarily remembered for his efforts to link Christian faith with social reform, arguing that the church must address systemic injustices and improve earthly social conditions to reflect the kingdom of God.
