The Economic Order and Religion [PDF ebook] 

First Published in 1998. In this highly fragmented culture of ours books are needed to integrate fields of interest ordinarily considered separately, to state their common problems and to deal with their differences in the light of other criteria than the separate functions and local loyalties of the special interests in themselves. This book was originated with that purpose in mind. Specifically this book deals with the practical dualism of our modern morals. With the traditional Christian ethic at one pole and the variegated, often contradictory assemblage of practices and precepts of our secular life at the other, it has never been co-ordinated or made intelligible from within.
