R. Travers Herford, Pharisaism, Its Aim and Its Method
“ And the Haggadah was the means by which this [251] general body of belief was continually illustrated and illumined, so that it might have ever renewed power to refresh the soul. Just as the Halachah was the detailed application of Torah to conduct, on its practical side, as the doing of the divine will, so the Haggadah was the detailed application of Torah to the spiritual life generally, so that the light which God had given might be shed over the "things which are eternal." ”
