The Christian Faith in the Modern World by J Gresham Machen.
During the first four months of the year 1935, the writer of this book delivered over Station WIP a course of radio addresses, for which the arrangements were made by the Rev. Edwin H. Rian, on behalf of Westminster Theological Seminary, Philadelphia. The addresses are now published in a form very similar to that in which they were delivered.
This resulting book may perhaps lay claim to a larger degree of unity than that which is usually possessed by published addresses, since these addresses proceeded in logical sequence. Little more than a beginning, however, is made of the treatment of the subject indicated in the title. The Christian view of the Bible and a part, at least, of the Biblical doctrine of God are presented (of course only in summary fashion); but other great elements in the Christian Faith - the Christian view of man and the Christian view of salvation - are left for future treatment.
