In this classic text, Karl Barth outlines and discusses the Christian tradition of baptism and its biblial and theological context. Karl Barth (1886-1968), the Swiss Reformed professor and pastor, was once described by Pope Pius XII as the most important theologian since Thomas Aquinas. As principal author of 'The Barmen Declaration', he was the intellectual leader of the German Confessing Church - the Protestant group that resisted the Third Reich. Barth's teaching career spanned nearly five decades. Removed from his post at Bonn by the Nazis in late 1934, Barth moved to Basel where he taught until 1962. Among Barth's many books, sermons, and essays are The Epistle to the Romans, Humanity of God, Evangelical Theology, and Church Dogmatics.
