Abstract
The reference to the Holy Spirit provides the starting point and doctrinal center for showing that Niebuhr, because of his uncritical acceptance of the explanatory range of science, has been unable to integrate his real longing for a truly Biblical Christianity with his refusal to admit the possibility of God's working miraculously in grace, which is in the highest sense the working of the Holy Spirit. The mystical and righteous elements of Biblical Christianity are redefined in terms of symbols that have as their referents individual, psychological and collective social adjustment. The author lacks a clearly and fully expounded notion of miracle.—E. A. R.
