One of the world's foremost exponent of the 'pluralist' position is the most adequate Christian theological account of religious diversity turns to a new and urgent issue facing the community of world religious. For Paul Knitter, the spectre of environmental and social injustice looms over any serious discussion of humankind's future. As urgent as it is to have peace among the world's believers to achieve peace among nations, it is urgent that these communities unite in understanding and defending of the earth. In One Earth Many Religions Knitter looks back at his own 'dialogical odyssey' and forward to the way that interfaith encounters and dialogue must focus attention on new challenges. Nothing less than enlisting the commitment of the world's religions on the task of saving our common home will do. In making that case, Knitter makes clear the complex structures political, economic and social as well as religious that face those who approach this task. While articulating a 'this worldly soteriology' necessary to overcome our eco human plight, Knitter offers practical considerations on actions and projects that have and should have been undertaken to stem the tide of environmental and human suffering.
