Inspired by spirit and documents of Second Vatican Council (1962-65), Dr. Leonard Swidler, theologian and historian, became a leading voice in ecumenical, interfaith, and interreligious dialogues worldwide. Whether as sponsor, host, or participant in conferences, meetings, or symposia, Swidler has been a leading theorist for dialogue among religious and ideological communities. His Decalogue has become ideal for dialogical encounters. (1) His 4-H's of Interreligious Dialogues: Head, Hand, Heart, and Holy identifies areas for fruitful dialogical exchange. (2) To meet need for publication of serious discourse in these emerging fields in 1964 with his late beloved wife Arlene, he established this Journal of Ecumenical Studies. His graduate courses and Dialogue Institute for International, Intercultural, and Interreligious exchange motivated many students from Temple University's Department of Religion to engage in and foster dialogue. I am among these students. Although Swidler's extensive writings do not focus on ecology, in Toward a Universal Declaration of a Global Ethic (3) he called for multinational/religious/ideological dialogues to establish an ethic that is anthropocosmo-centric. This call recognized that future dialogues must address challenges to natural world. (4) I am convinced that ecological concerns are today's most essential dialogue. While Swidler has rightly insisted that goal of dialogue is to learn more than to communicate one's own perspectives, dialogue assumes one has a perspective to offer. I live and teach in Alaska, canary to a worldwide ecological crisis. Here, villages of Kivalena, Shishmaref, Shaktoolik, Unalakleet, Koyukuk, and Newtok are already seriously threatened, if not yet irreparably destroyed, by climate change. Those truly familiar with situation accept that in thirty to fifty years, 193 more Alaskan Native Villages will either to move or disband, their present locations having become uninhabitable. Alaska is not only locus of Exxon Valdez oil-spill disaster in 1989 that ravaged waters and marine life of Prince William Sound, but it is also home to an oil-based economy populated by a significant majority of voices who deny scientific evidence of ecological concerns. While scientific and technological knowledge as well as industrialization greatly enhanced human comforts, these come at the price of unexpected consequences that proved increasingly disastrous for rest of creation as well as ourselves. (5) Environmental concerns (air and soil pollution, resource depletion, loss of biodiversity, overpopulation, climate change, etc.) are most pressing threat to humanity and to all other living beings. While disputes over natural resources preoccupied human history, if we fail to arrest ecological degradation, there will be no resources at all. Ecological concerns entered Christian discourse in response to an important article published in 1967 by Lynn White, claiming that Christian anthropocentricity was culpable for growing ecological problems. (6) In response, biblical scholars identified biblical texts for earth-affirming insights. These efforts to respond to secular critics who minimized every religion also led scholars and practitioners of other religious to identify ways in which they or their traditions appreciate and affirm nature. (7) It is thus that ecology became a topic for ecumenical, interfaith, and interreligious dialogues. Today, many recognize that all religious communities that determine how people understand nature and establish moral imperatives and values have potential to mobilize sensibilities of people toward goals of Earth Stewardship, here defined as shaping trajectories of social-ecological change to enhance ecosystem resilience and human well-being. (8) Statements identifying related concerns and protocols that been issued by religious bodies throughout world are posted on Forum on Religion and Ecology at Yale (9) Pope Francis is currently working on a much anticipated encyclical on environment, which will be an important addition to these statements. …
