Am interesting (to me at least!) fact and a helpful quote:
Machen studied under Wilhelm Herrmann in Marburg in Germany. Herrmann had two other famous students – Karl Barth and Rudolf Bultmann.
‘What Machen was searching for was neither an intellectualism devoid of faith nor a faith devoid of intellectual merit. Nor was he after either a rigorous scholarship without piety or a vital piety without roots in scholarship. He longed for piety and intellect fused into one, an intellectually informed and compelling faith.'
