The secret of Hegel's dialectic lies ultimately in this alone, that it negates theology through philosophy in order then to negate philosophy through theology. Both the beginning and the end are constituted by theology; philosophy stands in the middle as the negation of the first positedness, but the negation of the negation is again theology. At first everything is overthrown, but then everything is reinstated in its old place, as in Descartes. The Hegelian philosophy is the last grand attempt to restore a lost and defunct Christianity through philosophy, and, of course, as is characteristic of the modern era, by identifying the negation of Christianity with Christianity itself.
