And if Krause struck some roots here-more numerous and more permanent than is commonly supposed-it is because Krause had roots in pietism, and pietism, as Ritschl has demonstrated in his Geschichte des Pietismus, has specifically Catholic roots and may be described as the irruption, or rather the persistence, of Catholic mysticism in the heart of Protestant rationalism.
Eta Krause-k hemen sustrai batzuk egin bazituen-pentsa baino gehiago eta uste baino iraunkorragoak-, hori Krauseren sustrai pietistei esker izan da, eta pietismoak, Ritschlek haren historian frogatu zuenez (Geschichte der Pietismus) sustrai bereziki katolikoak dauzka, eta mistizismo katolikoak arrazionalismo protestantearen baitan eginiko erasoa edo, hobesanez, bertan izandako irautea esan nahi du.
