Unlike Luther’s singular struggle with Catholic tradition, modern evangelicals struggle with many challenges to their source of truth. Whether those challenges are represented by various forms of higher biblical criticism, naturalistic empiricism, pluralistic relativism, or neo-charismatic prophecy, the evangelical spirit seeks truth from the Scriptures alone. Based upon the resurrection of Jesus, we have assurance that this approach will prove true in the end. - John P. Harrigan, the Gospel of Christ Crucified, p.10
