Revelation

"We may, and must, emphatically protest against any two-sources-theory, which places Scripture and tradition, or Scripture and nature, or Scripture and history, on one line, as sources of knowledge of equal import [emphasis original]. Any such equalization has always resulted in a devaluation of Holy Scripture. But also every attempt to prove, on the basis of fallen mankind's blinded eyes, that God has revealed himself only by his Word, and not already in the works of his hands, must be rejected" (G. C. Berkouwer, General Revelation, 280).
