The Origin of Paul's Religion

J. Gresham Machen (1881-1937) was Professor of New Testament at Princeton Seminary, before leaving in 1929 to establish Westminster Theology Seminary and the Orthodox Presbyterian Church. Machen was one of the last intellectual defenders of orthodox Christianity in the seemingly triumph of liberalism in the early 20th century.

His best-known scholarly work, published in 1921, is "The Origin of Paul's Religion".
