There is a need for broader literacy and deeper knowledge of the world’s religions and their ecological contributions. This course is designed as a gateway to the rich ecological dimensions of the Christian religious tradition. We delve into unique contributions from Catholic, Orthodox, and Protestant Christianity, exploring views on and relationship with the natural world. We additionally highlight the relationship between Christianity and environmental justice, evangelical approaches to “creation care”, and Christian teachings on biodiversity, climate change, and the relationship between human, Earth, and cosmos. This course is for lifelong learners curious to know more about world religions and ecology, environmental professionals eager to deepen the discourse of environmental protection and conservation, those working with non-profit organizations and NGOs on issues of ecological justice, and religious leaders and laity who want to know how they can contribute to interreligious dialogue on environmental projects.
