J. Frank Henderson, Stephen Larson, Kathleen Quinn. Worldwide Web Edition, 1999. www.compusmart.ab.ca/ fhenders/LJRG.pdf.
This book was first published in 1989 by Paulist Press; when the book went out of print, the authors negotiated the rights to present it in its entirety (with a new preface) on the Web, so now it is accessible to everyone.
The book is a wonderful combination of perspectives and resources on the relationship between worship and justice. The many prayer and liturgical resources are available for the downloading. It is written from a Roman Catholic perspective, which has a long tradition of social justice activity around the world.
Also check out Frank Henderson’s website to learn of his continuing work in practical liturgical theology. A retired biochemist and cancer researcher, Henderson is a remarkably knowledgeable and gifted scholar with a passion for justice.
