Finney on Moral Government, etc.
Charles Finney is enjoying a tremendous resurgence of popularity on the Internet, as this site illustrates.
Revival Theology Resources
Writings from a number of authors who held to the "Moral Government" theory of the atonementa modern variety of Pelagianism.
The Restoration Movement
Background on the Campbellite movement, which gave rise to the Disciples of Christ and the Churches of Christ.
Karl Barth
This page touts Barth as "a church Father . . . among us, a theologian of such creative genius, prodigious productivity, and pervasive influence that his name is already being associated with that elite group of Christian thinkers that includes Athanasius, Augustine, Anselm, Aquinas, Luther and Calvin." Well, anyway, he's the Father of Neo-Orthodoxy. I guess that makes him a "Church Father" of sorts. But we would not include him in such rarefied company.
Dietrich Bonhoeffer
Bonhoeffer was a martyr who valiantly opposed German Nazism and paid for his resistance with his life. Some of his writings, particularly The Cost of Discipleship, and Letters and Papers From Prison endure as classic devotional works that challenge readers to deeper devotion to Christ. But Bonhoeffer's theology was tainted with neo-orthodoxy and existentialism. He was, in the final analysis, unorthodox.
The Origins of the Pentecostal Movement
Pentecostalism was the offspring of numerous unbalanced and erroneous movements, including the perfectionism of the holiness movement, the radical Arminianism of the revival movement, and an unwholesome anti-intellectualism.
